Very Strong – 129 bits
About this tool
Passwords are generated with the browser's cryptographically secure random number generator (crypto.getRandomValues). Use the Password tab for maximum strength in the fewest characters, or the Passphrase tab for passwords that are easier to remember and type — words are drawn from the EFF short wordlist (1,296 words).
The strength meter estimates entropy in bits: roughly, each additional bit doubles the number of guesses an attacker would need. Aim for 60+ bits for ordinary accounts and 100+ bits for anything critical.
