Questions and answers
How long should a password be?
At least 12 characters, ideally 16 or more. Length matters more than complexity: every extra character multiplies the number of possible passwords.
Is it safe to generate a password online?
Here, yes: the password is created in your browser with crypto.getRandomValues, the secure generator used for encryption, and it is never sent to a server or stored.
What do “bits of entropy” mean?
They measure how hard a password is to guess. Every extra bit doubles the number of attempts needed: 60 bits is fine for most accounts and 80 bits or more is very strong.
Can I use the same password on several sites?
Better not. If one site leaks it, attackers try it everywhere else. Use a different password for every account and a password manager to remember them.
