FAQ

What makes a password strong?

A strong password is long, random, and uses a mix of character types. The strength indicator evaluates entropy, which measures how many possible combinations an attacker would need to try. A password with 80 or more bits of entropy is generally considered very strong.

Is it safe to generate passwords in a browser?

Yes. This tool uses the Web Crypto API, which provides cryptographically secure random number generation built into your browser. No passwords are transmitted over the network or stored anywhere. Everything happens locally on your device.

How long should my password be?

For most purposes, 16 characters or more with a mix of all character types provides excellent security. If you use a password manager, there is no reason not to go longer since you will not need to memorize or type it manually.
