How To Remember Passwords
And Avoid A Password Leak

Last updated: March 2022. For beginners. No tech skills required.

Password length vs complexity

Ever lived through a password leak? This is a beginners guide to creating strong and unique, yet simple to remember passwords for your accounts, devices and encrypted files. We'll discuss some password length best practices and review open source password managers such as Keepass XC, Keepass DX or Strongbox, as well as how to enable 2FA (which is a form of multi-factor authentication).

Diceware & password entropy

Diceware is a popular password generation method. All you need is a dice, a pen and a piece of paper. If you choose a password composed of at least 7 words, this is considered as virtually unbreakable by today's technology standard. Read on below to learn more.

Steps Instructions
1 Select a Diceware word list. For example the original list, or the list provided by the Electronic Frontier Foundation. There are many others to choose from, in several languages.
2 Roll a dice 5 times and write down the numbers.
3 Look up the corresponding word in the Diceware list, and write it down.
4 How long should a password be? Repeat the previous steps until you have at least 6 words. Actually, 7 words are recommended – depending on the password entropy calculator, this achieves an entropy of approximately 90 bits. According to Diceware's FAQ, this is unbreakable with any known technology, but may be within the range of large organizations by around 2030. Eight words should be completely secure through 2050.
5 The combination of these words is your secure password. Make sure to separate the words by a space.

How to enable 2FA & generate backup codes

Two-factor authentication (2FA) provides an additional security layer. It requires more than just a password to access services or accounts. For example, a single-use verification code sent by SMS or generated by an authenticator app or key.

While two-factor authentication is generally considered to increase security, it offers additional surface for cyber-attacks such as Phishing, identity theft (SIM swap attack) or SMS hijacking (SS7 attacks). It is also less convenient to the average user.

We're not going to describe the benefits of multi-factor authentication. All in all, we would advise two-factor authentication. Choose for yourself if this brings additional benefits, depending on your threat modeling. If you go for it, don't forget to safely store the backup codes that some services provide. They can be life savers when you loose access to your phone or authentication program.
