What does Password Generator do?

Strong, unique passwords are the simplest defense against account takeover. This generator creates cryptographically random passwords with rules you control.

Passwords are generated locally using the browser's secure randomness and are never transmitted.

Generate cryptographically random passwords.
Control length and character types.
Generate locally — nothing is sent over the network.

Common use cases

Creating a strong account password
Generating credentials for a new service
Producing random keys or secrets
