Password Generator

Create strong passwords up to 64 characters from uppercase, lowercase, numbers and symbols. Passwords are generated locally using crypto.getRandomValues and are never transmitted.

How to use the Password Generator

  1. Set the length.
  2. Choose character types.
  3. Copy the password.

How it works

Strength reflects entropy: length × log2(character set size). Use unique passwords for each account and a password manager.

Good to know

Avoid look-alike characters if you must type the password manually.
