Is this password generator safe?

Yes. Passwords are created in your browser with crypto.getRandomValues, a cryptographically secure random generator. Nothing is sent to our server or saved, and the page works offline once loaded.

How long should a password be?

Use at least 12 characters, and 16 or more for email, banking and other important accounts. Length adds more strength than complexity: a 16-character password with all character types has about 105 bits of entropy.

What does the strength in bits mean?

Entropy in bits measures how many guesses an attacker would need: every extra bit doubles it. Under 50 bits is weak, 50–79 is fair, 80–99 is strong and 100 or more is very strong.

Should I reuse a generated password?

No. Use a different password for every site so one leak cannot unlock your other accounts. A password manager can remember them for you.
