Password generator

Create a password or several options. Passwords are generated on your device and are not sent to a server.

Characters to use

12 to 128 characters, up to 10 passwords at a time. Each password contains at least one character from every selected group.

A short, digits-only password is easier to brute-force. Cryptographic randomness does not compensate for a short length or a small character set.

Where does the randomness come from?

The generator uses the browser’s system cryptographic source through Web Crypto. If it is unavailable or returns an error, generation stops. Clocks, counters and Math.random are not used.

Which settings should I choose?

The default is 20 characters using all four groups. Check the destination site’s requirements for length and symbols. Use different passwords for different accounts and save them in a password manager.

Are passwords stored?

This page has no third-party analytics counter. Passwords are not written to localStorage, a generation history or the URL. Generating again, changing settings or clearing removes the previous result. Copying places the password on the system clipboard only when you click.
