The number 1 problem in cryptocurrencies today is that people are losing their passwords. Forget about hackers and scammers, those are nothing compared to how many people are locked out of their money due to losing a password. I see people constantly on Bitcointalk screaming for help because their password is lost.

So to avoid [tragedies like these](https://bitcointalk.org/index.php?topic=85495.0) you should immediately start using a password manager. In this tutorial I am going to talk about how to setup easily and use KeePassXC, the best and safest password manager in my opinion. There you can safely store passwords or even private keys, in encrypted format.

First of all KeePassXC is an innovative fork of KeePassX with trusted developers, it's open source, so fuck the closed source password managers, you should not trust those. And it comes with tons of new features like OTP and TOTP systems as well as a better GUI.

# 1) Download & Verify KeePassXC -- SECURELY

<BR/>

Download it from here: https://keepassxc.org

Make sure it's HTTPS, verified by Let's Encrypt, the last thing you want is to download a malware from a phishing website. Then also [verify the download](https://keepassxc.org/download), I'll be using the Linux portable version, and I really don't recommend people using Windows, just install a Linux operating system it's safer!

<center>![z1.png](https://steemitimages.com/DQmUfBBPtNNxi8knjj4ZKmWa9vKdHS6E5T2LmWJnQpnKCtr/z1.png)</center>

The Linux "Appimage" which is just a portable binary, but you can install it to `root` mode from the options available below, but I like the portable version, it can be put on a USB stick basically and the stick hidden away from thieves, so it offers strategic advantages.

In my case the version currently is `2.20` the file name is `KeePassXC-2.2.0-x86_64.AppImage`

Then verify the SHA256 hash by downloading that file too, for me the hash is:
`d33640268b43496cb0f1906191404977d60ec6933c0ed827643c3fc1a6ac151e`

Steemit posts become uneditable after 7 days so this is a good reference point to verify the authenticity, and compare this with your hash file, and the hash output of the application file which you get by opening the terminal in the same folder as the file is and typing in:
`sha256sum KeePassXC-2.2.0-x86_64.AppImage`

If the terminal output, the file hash (downloaded) and the hash I write above, all 3 match, then it's a good sign that the file downloaded is authentic, otherwise you could be a victim of an [MITM attack](https://en.wikipedia.org/wiki/Man-in-the-middle_attack).

Then also verify the signature of the file, to verify that the file comes from the developers, here is a tutorial:
* https://keepassxc.org/verifying-signatures

Import the developer's public key:
`gpg --keyserver pool.sks-keyservers.net --recv-keys 0xBF5A669F2272CF4324C1FDA8CFB4C2166397D0D2`

Then download the GPG signature from the same page you downloaded the SHA sum, then open the terminal again from the same folder and check the public key against the signature, by entering this in the terminal:
`gpg --verify KeePassXC-2.2.0-x86_64.AppImage.sig`

It should show this:
<center>![O1.png](https://steemitimages.com/DQmfLG3frQsBuNKnfxcV96XUrh3ybnevcYrmXFjJ5QaYxGj/O1.png)</center>

Make sure the Primary Fingerprint matches mine:
`BF5A 669F 2272 CF43 24C1  FDA8 CFB4 C216 6397 D0D2`

If they don't match then you have probably downloaded a malware version of it. Sorry for all this fuss, it's technical and uncomfortable, but remember we are downloading a password manager, where you will probably store all your cryptocurrencies's related passwords, and you really don't want to download a malware.

I mean it's critical for people to store their passwords safely and to know that the software they are using is real, genuine and trustworthy. So don't even think about using Windows if you are serious about security, just use [Linux Mint](https://linuxmint.com/) or [Debian](http://www.debian.org/).

# 2) Using KeePassXC

I am using the portable version, so just start that, make it an executable and it runs:

<center>![1.png](https://steemitimages.com/DQmc6D69bgTVH3Asw1m5Ar4U6KReym79JBSZ7QMMi5Rj6fD/1.png)</center>

When you first run it you will have to create a database file that will store all your passwords, you will always have to back this up after adding or changing passwords in it. Obviously if you add a new password to it, it won't be present in an older file, so make sure you always back this file up.

<center>![6.png](https://steemitimages.com/DQmbXXL4siFYq3URpAfU5kSDtkR93FD8Ugq36DHmrddgJKo/6.png)</center>

As you can see I already created a database file named `Passowrds.kdbx`, there are 2 ways to access it, either it's master password protected, or you open it with a key (which I have created there `keyfile`), or both. If the database will be master password based then use a good long strong password (which I will show you in a moment how to generate) and memorize that, write it down, or whatever. Remember without the password the database can't be opened!

An alternative is to use a keyfile, here named `keyfile`, which you can generate by pressing the `Create` button, and then copy the keyfile to like a micro-SD card and hide that away. So in this case you can just open the database when you plug in the micro-SD card, and it will remember the path of the file. Easy access, but again, if you lose the keyfile or the card, then it's all lost, so proceed with caution and make backups if necessary.

Remember the database file is basically public, it is an encrypted file so you don't have to worry about it being cracked, you can even upload it to places like Dropbox if you worry that your PC crashes, or make many copies of it to many USB sticks. Especially if the file is large like it can get up to 10-100 MB if you hold many stuff in there and add custom icons and things like that.

**But the keyfile should be always kept secret, don't make that public ever, same with the master password, in fact it should be generated offline as well!**

### Master Password Generation

You can generate a strong password (for master password of the database for example) by clicking on the dice icon:

<center>![3.png](https://steemitimages.com/DQmZ8Co53ocnW2yoxozy6giZhEuGaaY2a9fKgz9c5diZyiG/3.png)</center>

You can set there how complex the password should be (numbers,caps,symbols) but it should have minimum `128 bits entropy`!

[Entropy](https://en.wikipedia.org/wiki/Entropy) measures the "size of the haystack" of possibilities of your password, in this case 128 bits is  a haystack of the size of 2<sup>128</sup> combinations, which is pretty impossible to guess.

<center>![4.png](https://steemitimages.com/DQmQMp7mZWCsHfhp1iRRwSzzJ6x7nZKXkmBFTCAEndWGSPH/4.png)</center>
 
This password is decent if I can say so. Also you can use (and should use) passphrases instead which are easier to memorize:

<center>![5.png](https://steemitimages.com/DQmcvRVGmYMixqkoSVTSxzC8hkaEZAsuenzKdauwo26PKhW/5.png)</center>

So after you have created your database file (here `Passowrds.kdbx` already created), you can customize it’s strength by choosing it’s properties, by going to DATABASE>DATABASE SETTINGS:

<center>![7.png](https://steemitimages.com/DQmPsR758qPYFvesBvHLjXPqXYwurmnrs9NmPAgaQsKhW5B/7.png)</center>

Leave the algorithm to [AES-256](https://en.wikipedia.org/wiki/Advanced_Encryption_Standard), but you can change the round size, if you click on benchmark it will set it to a number so that the database will open in 1 second.

[NIST](https://en.wikipedia.org/wiki/NIST) recommends 10,000,000 rounds I believe, so if speed is not an issue then set it to that, but if the file gets large like >10 MB then this will slow down the user experience.

So either leave it like that, but if you plan to upload the database as a backup to public [PRISM](https://en.wikipedia.org/wiki/PRISM_%28surveillance_program%29) places like Dropbox or Google Drive, then you should definitely set the round number to 10m or even higher!!!

### Add Password Entries

Then after the database is created, backed up and customized to your needs, then start adding passwords here, or copy them out from Firefox or Chrome’s login/password bookmark lists, it’s much safer to store passwords in a database like this than in Firefox or chrome, and you can auto-type them into the login pages so no need to manually enter them.

Add a new password entry for example:

<center>![8.png](https://steemitimages.com/DQmRTJ8oS1GQhvtNgYgaBmkpqbNiRxQzCs4EpMCfp1CLseb/8.png)</center>

Make sure you add the URL of the login link, I think it has to be the exact full link, so for Steemit it’s not `https://steemit.com` but `https://steemit.com/login.html` so make sure it’s the exact URL.

Then choose an icon for it:
<center>![10.png](https://steemitimages.com/DQmd6sQEZne2jamVK15a71w1Ercm4MZMcc71vmZHUWoXVkU/10.png)</center>


Your first entry will look like this, in the `Root` main folder, but you can also customize it:
<center>![9.png](https://steemitimages.com/DQma4F9g4x1MrJzc5qC5TR4G5VK4RaUSPRwyC2jbc6NgzC2/9.png)</center>



Then just add groups there fore different things, and drag entries from 1 group to the other, organize it as you wish, pretty easy to learn, just drag items basically:

<center>![11.png](https://steemitimages.com/DQmbw2BjQFRDztjd1poPCNdcBoKCR3nXP537ZkkY2kxUKTS/11.png)</center>

After you are done, back up the database, store it well and don’t lose nor expose your password or keyfile associated with it.

# Conclusion

KeePassXC is the safest, most tested and most easy to use password manager in my opinion. With it’s new gorgeous design and features it helps you store your cryptocurrency related passwords and secrets safely.
Of course this only works if you are careful, like have a secure PC, or perhaps use KeePassXC in a non-networked computer. It’s your decision and your responsibility to store your passwords safely.

However this software makes it easy, instead of storing them on pieces of paper that get lost or browser login lists, which are insecure due to Javascript problems and things like that. No browser is sandboxed so no password stored there is safe, so storing in a safe database like this is better.

The database itself should always be backed up, again the database can be public, but the password or the keyfile should not be. So a database backed up on multiple USB sticks and on Dropbox or Google Drive, meanwhile using a secret keyfile to open it, that is stored on multiple micro-SD cards hidden well away in multiple places is a good idea.

When you use the software, you can just open the link of the website you want to login and press `CTRL+V` to auto-type the login/password into that page, or copy it manually, where the clipboard will be erased in 10 seconds, so you can browse after that safely, or set that timer to less in the options, if you can copy it quicker.
