In this article, we'll take a deep dive into password managers, which applications to go for, how to optimize your password managers and which ones to avoid. It's of increasing importance for all users to adopt a password manager because commonly used passwords and repeated use of log-in + password combinations are the two weakest points in any normal individual's security online. Meanwhile, memorizing dozens of unique and complex passwords is beyond the scope of what most people can do, especially long term. Thus password managers have been created as a way to store multiple passwords into a single file that can help ensure your security and privacy online.
For a little encouragement, we'll share the now extremely famous dialogue between Edward Snowden and John Oliver talking about passwords. As should be painfully obvious by now, password managers are one of the best solutions to this entire dilemma.
PASSWORD MANAGER BASICSWe should first note that not all password managers are created the same as we've noted with software across all of our other articles. By and large, we'll be looking for similar characteristics in our password managers as we would our other software which includes open sourced software protocols and best software security practices. And when it comes to Bitcoin, cryptocurrency and your entire life's work on the internet, there is a lot at stake here. I'd argue that it is more important for password managers than for any other application to make sure to get this one correct since it will have your entire livelihood on the line.
The very amazing thing with demanding open sourced software for your password manager is that it by definition will also be free at the most basic level. This is because if it weren't, all it would take would be someone to fork over a program to make it free. So you are in a sense getting the best of both worlds here; a free software that is also of the highest quality. Meanwhile, ironically, many of the more commonly known password managers like Dashlane or Lastpass use closed source software and often charge fees to use their service. Funnily enough, Lastpass, the password manager itself, was actually formerly hacked in the past. One could argue this at least in part had to do with it's closed source software since having open sourced software at least in part makes software more secure. In short, do not used these closed source services that are frequently advertised for on the web as they are detrimental to you in more ways than one.
RECOMMENDED BEST PASSWORD MANAGERSBitwarden is our first recommendation. Bitwarden is truly one of the all time greats by approaching password management on the individual, team and even enterprise level to create a one size fits all solution. Bitwarden is compatible on virtually all devices out there from all desktops to mobile devices and so forth. Additionally, while they offer a centralized cloud service for free, Bitwarden is also set up to allow you to run your own private server to keep your own key base entirely under your own control, fully encrypted.
Next up we have KeePassXC which is a fork of one of the longest standing password managers in existence, formerly known as KeePass that halted a lot of it's ongoing development some time ago. KeePassXC was created as a locally held password manager application that could work across platforms. Unlike Bitwarden where your key file is held in cloud storage, KeePassXC is simply a program client and a local file that you must maintain and backup yourself. This has some pros and cons. The good news is that you have full control of everything related to KeePassXC as the program under most situations will not be talking to any online server which could expose private or sensitive information. The bad news is that if you ever were to lose control of your key file, you are completely out of luck. For this reason, it's imperative to back up your encrypted key file in multiple locations to protect against what would be catastrophic loss. You can do this with USB drives, e-mail accounts, cloud storage, safe deposit boxes or a whole host of other creative solutions that you might come up with.
The final recommended option is LessPass. LessPass is very interesting technology because it is a no-knowledge password manager. By inputting a few pieces of information which could be a master password in conjunction with an e-mail address or user name, a password is automatically attached to any URL address. It will simply cross all of these pieces of information via PBKDF2 and SHA-256 to produce random yet consistent outputs for any of your web browsing. The advantage of this program is that it is extremely light weight, and so long as you can remember your e-mail address, account name and master password, you can now gain full access to everything around the internet without the need of any files. The downside is some level of control over password flexibility since the passwords are automatically generated for you.
In summation of these three options, BitWarden is the best overall password manager for most people's use cases. Meanwhile, LessPass is probably best suited for the most casual user who contains fewer accounts across the internet and wants something extremely simple and easy to use. Lastly, KeePassXC, will be the ultimate in privacy password manager technology and is best suited for those that are prepared to take the extra steps to ensure their key file is kept up to date as the months and years tick by.
BEST PRACTICES WITH YOUR NEW PASSWORD MANAGEROnce you have chosen a password manager from the above list, it will be important to change all of your account passwords one by one to incorporate it into your new system. This will help you get away from your commonly used log-in and password combinations and over to your new, more secure and robust set up. With your new set up, if you have a key file to back up, you must now start getting in the habit of doing so, especially after major or important changes to your password manager. Or if you wish to use BItWarden with a private cloud server, make sure that that is fully set up and running.
Generally speaking, when choosing password length from your password manager for standard and robust security, 25 random characters, letters (and symbols if you wish, but they aren't necessary), is mostly considered to be uncrackable. This is because while every password is in theory beatable, it takes dramatically more computational energy over time to figure out what your password is, and at some point, it becomes unreasonable. That said, NSA grade security often holds itself up to 50 random characters which is considered to be unbreakable even on a government wide scale.
On that same token, you'll have to use a master password for your password manager. Given that you only need to know one password, it will now be extremely important to make this a very good password. Because a password that you need to remember most likely won't (or perhaps shouldn't) be completely random so that it's easy to remember, it should, at the very least, be long. I would suggest making sure that you come up with a master password that is at least 40 characters long or 125 bits of information. To check out how many bits of entropy your master password is, you can type it into the password field of KeePassXC and it will tell you roughly how secure your master password is. While 40 characters may seem like a lot, do keep in mind that this is now the only gateway between yourself and all of your access keys to all of your accounts held on this account.
Bits of Entropy Example on KeePassXC
Finally, it is worth investing in a YubiKey or similar 2-FA device if you can get one. This can apply to BitWarden and KeePassXC. With the normal password managers, a hacker will need access to not only your password but also your key file in order to have free reign over all of your accounts. However, a sophisticated hacker that has full access to your device with a keylogger could ultimately, in theory, compromise your full set up, and this would be disastrous for you. Fortunately, this can be resolved by buying and activating a Yubikey or other such device. The Yubikey example requires that a Yubikey, with a private key that you set up for your password manager, is present to access your database. Therefore, even if a hacker were to obtain your key file and your master password, they still won't be able gain access to your account. As a precaution, however, if you lose access to your Yubikey and/or private key, you too, will be locked out. Therefore, it is important to keep your Yubikey backed up and to keep extra copies available.
IN CONCLUSIONOwning Bitcoin or other cryptocurrencies comes with a lot of responsibility if you want to minimize risk. As does maintaining a strong hack-resistant presence online. One of the best defenses you can make is by implementing a password manager. Similar to the previous CryptoSmarts articles that we have written prior, it will take some small amount of set up work to get fully acclimated to your new system, but you'll thank yourself down the road that you have done this. And the sooner you start, the better, as things will only continue to get more complex, with more risk factors at play as the internet plays an ever increasing role in all of our day to day lives.
Finally, while the article is current as of the writing of the article, it will undoubtedly lose merit over time. Be sure to check if everything in this article is up to date or that any password manager that you select from this article continues development or continues to abide by the proper best practice principles.
If you enjoyed this article, we would encourage you to check out our other previous CryptoSmarts articles discussing private e-mails, secure messenger applications and proper web browsers.

Bitcoin SV (Satoshi Vision). Un fork de un fork del Bitcoin Core (BTC) a partir de las discrepancias en escalabilidad y tamaño de bloque.
Veamos qué dice Coinpaprika:
Bitcoin SV – is a new coin splitted of Bitcoin Cash blockchain on 15 November 2018. Four fundamental pillars form the basis of Bitcoin SV’s roadmap to create the one blockchain for the world: stability, scalability, security, and safe instant transactions (a.k.a 0-confirmation). The Bitcoin SV project was created at the request of and sponsored by Antiguan-based CoinGeek Mining, with development work initiated by nChain. The project is also owned by the Antiguan-based bComm Association on behalf of the global BCH (SV) community, and the Bitcoin SV code is made available under the open source MIT license.Qué tiene de bueno BSV? Estabilidad, escalabilidad, seguridad y transacciones seguras e instantáneas. Yo no tengo queja con ninguna de ellas. Las transferencias son muy rápidas (segundos) y con una fee razonable. Incluso asumidas en muchos casos por el proveedor.
La escalabilidad (banca) y el tamaño de bloque (multimedia) serán fundamentales a futuro.
“The existing Visa credit card network processes about 15 million internet purchases per day worldwide. Bitcoin can already scale much larger than that with existing hardware for a fraction of the cost. It never really hits a scale ceiling.” – Satoshi Nakamoto (April 2009)https://preview.redd.it/w6voga5ly2p51.jpg?width=2256&format=pjpg&auto=webp&s=c08304e64764e01515c379b8d9bcac35f3c7c3f4
BTC podrá seguir añadiendo capas paralelas, parches y demás que ya contempla BSV de base. No sé si es una solución que pueda alargarse en el tiempo, por lo que no parece que compitan en la misma liga. Queda por ver si complementarias o excluyentes …
Qué tiene de malo BSV? Es otro proyecto más? Si bien los números y la visión es ganadora, no siempre lo mejor es lo más extendido ni lo más adoptado. Lo peor que tiene BSV … es que no es BTC. Ni BCH. Hay multitud de haters atacando el proyecto y a su promotor principal Craig Wright. Autoproclamado como Satoshi Nakamoto, el promotor está envuelto en líos judiciales en el caso Kleiman (su socio fallecido) en el que los herederos de éste reclaman una fortuna (estimada en 1,1 millones de BTC) de cuando trabajaban conjuntamente. Más info:
https://es.cointelegraph.com/news/craig-wright-must-prove-access-to-11m-btc-fortune-by-april-17Noticias como ésa, unida a los haters de profesión (que lógicamente defienden “lo suyo”), ha convertido a BSV en una moneda controvertida que no deja indiferente a nadie. Para ver un ejemplo claro, Binance lo delistó arrastrado por la numerosa comunidad que atacaba a Craig Wright. Sin embargo, las pools de esa misma Binance están minando BSV mayoritariamente porque es una moneda rentable.
BSV no parece una moneda especulativa, ni intradía. Sigue las variaciones del mercado, con subidas y bajadas locas (como todas), pero apunta más a un largo plazo. Cinco, diez años.

Decentralized blockchain projects are gaining more and more popularity each day as the world realizes the potential of this blockchain technology. FLETA has decided to cooperate with other projects to drive the adoption of blockchain technology, facilitate technological innovations, and expand its network. In this article, we will introduce FLETA and other blockchain projects collaborating with us.
FLETAFLETA is a blockchain platform for decentralized applications aimed at solving some of the blockchain’s biggest hurdles. They have made advances to solve the scalability issues, but still keeping the blockchain fast and decentralized through a unique consensus algorithm known as Proof-of-Formulation.
Formulators are the key to FLETA’s technology. They are the block generators who mine and create new blocks. The mining process is configured in such a fair way that every formulator will get a chance to generate a block. This prevents conflicts and abuse because every miner is equal.
Generated blocks are confirmed and signed in real-time by Observer Nodes. They are responsible for securing the network, preventing DDOS attacks, and making forks impossible. Forks cannot happen on FLETA because 3 out of 5 Observers are required to sign and confirm the block. The first block with 3 signatures is the only valid one.
Proof-of-Formulation has been tested and verified in real-life scenarios. It is capable of achieving 14,000 transactions but remains highly secure due to the exclusive connection between Formulators and node Observers.
Matic NetworkThe Matic Network hopes to improve the scalability of Ethereum, by using PoS side chains, but without losing the critical elements of decentralization.
Matic’s multiple side chains possibly scale to millions of transactions each second in the future. The transaction fees are inexpensive, and its Plasma framework results in new blocks being generated in less than 2 seconds. It makes Matic a well-suited platform for micropayments.
FLETA is using Matic’s Plasma framework solutions on its Mainnet. FLETA has an auto-swap feature between the FLETA ERC-20 token and its native FLETA coin. The two projects have cooperated to improve the Deposit & Withdrawal options on FLETA and making them more decentralized.
TomoChainTomoChain is a blockchain platform that uses a Proof-of-Stake Voting Consensus to combat scalability. It is based on a network of 150 Masternodes. This technology allows a network throughput of 2,000 transactions per second and a 2 seconds blocktime.
TomoChain can be used by developers to build their own DApps. Also, by taking advantage of the TomoX Protocol, they can launch a decentralized exchange. The TomoP Protocol is a privacy feature allowing anonymous transactions. When enabled, it conceals information about the transacting parties, used addresses, and transaction amounts.
FLETA and TomoChain have signed a technical agreement that foresees the use of the TomoZ Protocol that allows fees to be paid with different tokens. FLETA will be creating a FLETA Token that can provide broader use cases within the TomoChain ecosystem.
NeoNeo is an open-source blockchain platform that uses smart contracts to digitize assets. The ownership of physical items from the real world can be registered, traded, and transferred via the Neo blockchain. Neo is a strong development platform that supports multiple coding languages and has an experienced development community.
FLETA and Neo have signed a strategic partnership, which entails the use of NeoVM on FLETA’s Mainnet. NeoVM is a lightweight and scalable virtual machine for smart-contract development. With its cross-platform compatibility, FLETA will significantly benefit from it.
Once deployed, FLETA and Neo will cooperate on several projects. The first planned one is a blockchain-based Real World Data-based Clinical Research Data Registry Platform for the medical industry. The project aims to activate medical data research and help researchers efficiently use the data.
WanchainWanchain is a cross-chain compatible infrastructure that seeks to connect the world of decentralized finance into one interoperable ecosystem. Different blockchain systems are incompatible with each other, and they operate on their own. The answer to this is creating wrapped tokens of the original assets and incorporating them on the Wanchain platform.
It allows the coins to be used in ways that weren’t possible before. For example, a wrapped Bitcoin token can be used in an Ethereum smart contract to take advantage of the Ethereum blockchain. The token can be easily exchanged back to real Bitcoin by using Wanchain technology.
Wanchain is based on the codebase of Ethereum, but it uses a PoS consensus algorithm. The project has established a partnership with FLETA. With this understanding, both companies expect further to improve interoperability and the performance of their systems.
WINkWINk is a gaming platform offering Live Casino Games, virtual sports, Slots, and E-gaming. WINk was previously known as TronBet, and it is located on the TRON Mainnet.
The platform supports several different tokens: TRX, Dice, USDT, BTT, and of course, WIN token. Besides being a gaming community, WINk also features a staking option. By staking WIN tokens, users get the chance to earn daily staking rewards from the platform’s profits.
WINk plans to integrate with Wallet Street, the social data platform of FLETA. Wallet Street allows stakeholders to communicate and create online communities. The two platforms will start a joint marketing campaign. Wallet Street allows its users to build their own buildings based on the number of coins they own. These structures become visible on a virtual map on Wallet Street. A WINk building will be constructed on Wallet Street’s map to advertise WINk project and its token.
ConclusionCooperation is essential for the crypto industry as it opens new possibilities. The sharing of information and knowledge is beneficial to success. Entering new markets allows companies to expand their user base. A broader reach increases use cases for blockchain technology and achieve the ultimate goal: massive adoption. FLETA has realized the importance of strong partnerships, and during 2020, their services will be taken to a whole new stage.
Yes. You pick a peer and after some setup, create a bitcoin transaction to fund the lightning channel; it’ll then take another transaction to close it and release your funds. You and your peer always hold a bitcoin transaction to get your funds whenever you want: just broadcast to the blockchain like normal. In other words, you and your peer create a shared account, and then use Lightning to securely negotiate who gets how much from that shared account, without waiting for the bitcoin blockchain.
Yes, Lightning is open source. Anyone can review the code (in the same way as the bitcoin code)
Similar to the bitcoin network, no one will ever own or control the Lightning Network. The code is open source and free for anyone to download and review. Anyone can run a node and be part of the network.
No, your bitcoin will never leave the blockchain. Instead your bitcoin will be held in a multi-signature address as long as your channel stays open. When the channel is closed; the final transaction will be added to the blockchain. “Off-chain” is not a perfect term, but it is used due to the fact that the transfer of ownership is no longer reflected on the blockchain until the channel is closed.
Example: A and B have a channel. 1 BTC each. A sends B 0.5 BTC. B sends back 0.25 BTC. Balance should be A = 0.75, B = 1.25. If A gets disconnected, B can publish the first Tx where the balance was A = 0.5 and B = 1.5. If the node B does in fact attempt to cheat by publishing an old state (such as the A=0.5 and B=1.5 state), this cheat can then be detected on-chain and used to steal the cheaters funds, i.e., A can see the closing transaction, notice it's an old one and grab all funds in the channel (A=2, B=0). The time that A has in order to react to the cheating counterparty is given by the CheckLockTimeVerify (CLTV) in the cheating transaction, which is adjustable. So if A foresees that it'll be able to check in about once every 24 hours it'll require that the CLTV is at least that large, if it's once a week then that's fine too. You definitely do not need to be online and watching the chain 24/7, just make sure to check in once in a while before the CLTV expires. Alternatively you can outsource the watch duties, in order to keep the CLTV timeouts low. This can be achieved both with trusted third parties or untrusted ones (watchtowers). In the case of a unilateral close, e.g., you just go offline and never come back, the other endpoint will have to wait for that timeout to expire to get its funds back. So peers might not accept channels with extremely high CLTV timeouts. -- Source
Tiny payments are possible: since fees are proportional to the payment amount, you can pay a fraction of a cent; accounting is even done in thousandths of a satoshi. Payments are settled instantly: the money is sent in the time it takes to cross the network to your destination and back, typically a fraction of a second.
Yes, but not in theory. You could make a poorer lightning network without it, which has higher risks when establishing channels (you might have to wait a month if things go wrong!), has limited channel lifetime, longer minimum payment expiry times on each hop, is less efficient and has less robust outsourcing. The entire spec as written today assumes segregated witness, as it solves all these problems.
No, for now. For the first version of the protocol, if you wanted to send a normal bitcoin transaction using your channel, you have to close it, send the funds, then reopen the channel (3 transactions). In future versions, you and your peer would agree to spend out of your lightning channel funds just like a normal bitcoin payment, allowing you to use your lightning wallet like a normal bitcoin wallet.
Not really. Anyone can set up a node, and so it’s a race to the bottom on fees. In practice, we may see the network use a nominal fee and not change very much, which only provides an incremental incentive to route on a node you’re going to use yourself, and not enough to run one merely for fees. Having clients use criteria other than fees (e.g. randomness, diversity) in route selection will also help this.
Lightning is already being tested on the Mainnet Twitter Link but as for a specific date, Jameson Lopp says it best
Nope, because there is no custody ever involved. It's just like forwarding packets. -- Source
Furthermore, the Lightning Network scales not with the transaction throughput of the underlying blockchain, but with modern data processing and latency limits - payments can be made nearly as quickly as packets can be sent. -- Source
Each exchange will get to decide and need to implement the software into their system, but some ideas have been outlined here: Google Doc - Lightning Exchanges
Note that by virtue of the usual benefits of cost-less, instantaneous transactions, lightning will make arbitrage between exchanges much more efficient and thus lead to consistent pricing across exchange that adopt it. -- Source
According to Rusty's calculations we should be able to store 1 million nodes in about 100 MB, so that should work even for mobile phones. Beyond that we have some proposals ready to lighten the load on endpoints, but we'll cross that bridge when we get there. -- Source
No you'd remember the information from the last time you started the app and only sync the differences. This is not yet implemented, but it shouldn't be too hard to get a preliminary protocol working if that turns out to be a problem. -- Source
Lightning is based on participants in the network running lightning node software that enables them to interact with other nodes. This does not require being a full bitcoin node, but you will have to run "lnd", "eclair", or one of the other node softwares listed above.
All lightning wallets have node software integrated into them, because that is necessary to create payment channels and conduct payments on the network, but you can also intentionally run lnd or similar for public benefit - e.g. you can hold open payment channels or channels with higher volume, than you need for your own transactions. You would be compensated in modest fees by those who transact across your node with multi-hop payments. -- Source
Sure, you can help write up educational material. You can learn and read more about the tech at http://dev.lightning.community/resources. You can test the various desktop and mobile apps out there (Lightning Desktop, Zap, Eclair apps). -- Source
No -- Source
lit doesn't depend on having your own full node -- it automatically connects to full nodes on the network. -- Source
LND uses a light client mode, so it doesn't require a full node. The name of the light client it uses is called neutrino
Upon opening a channel, the two endpoints first agree on a reserve value, below which the channel balance may not drop. This is to make sure that both endpoints always have some skin in the game as rustyreddit puts it :-)
For a cheat to become worth it, the opponent has to be absolutely sure that you cannot retaliate against him during the timeout. So he has to make sure you never ever get network connectivity during that time. Having someone else also watching for channel closures and notifying you, or releasing a canned retaliation, makes this even harder for the attacker. This is because if he misjudged you being truly offline you can retaliate by grabbing all of its funds. Spotty connections, DDoS, and similar will not provide the attacker the necessary guarantees to make cheating worthwhile. Any form of uncertainty about your online status acts as a deterrent to the other endpoint. -- Source
You typically want to have more than one channel open at any given time for redundancy's sake. And we imagine open and close will probably be automated for the most part. In fact we already have a feature in LND called autopilot that can automatically open channels for a user.
Frequency will depend whether the funds are needed on-chain or more useful on LN. -- Source
You don't really set up a "node" in the sense that anyone with more than one channel can automatically be a node and route payments. Fees on LN can be set by the node, and can change dynamically on the network. -- Source
Yes but it has to be implemented in the Lightning software being used. -- Source
You won't have to do anything. With autopilot enabled, it'll automatically open and close channels based on the availability of the network. -- Source
