Strong password generator

About this tool

A strong password is long and random. Each extra character multiplies the number of possible combinations, which is why length matters more than complexity. This tool shows the estimated entropy in bits: 80+ bits is strong, 100+ is excellent.

FAQ

Is this password generator safe?

Yes. Passwords are created in your browser with the Web Crypto API (crypto.getRandomValues), a cryptographically secure random source. Nothing is sent over the network or stored.

How long should a password be?

At least 12–16 characters for normal accounts; 20+ for important accounts such as email and banking. Use a password manager so you do not need to remember them.
