It's less complicated than what I'm reading here.

* Use a passphrase of at least five random words.[1]

* Keep that passphrases secret.[2]

* Use a password manager like 1Password or Keepass to generate and manage all other passwords.[3]

[1]: Good passwords have high entropy and are easy to remember. For that reason, passphrases are preferred to passwords.

[2]: It's ok to write down your passphrase, but keep it somewhere safe -- like your wallet.

[3]: Password managers prevent password reuse and make life easier. Sync passwords across devices.
