Is it secure?

Passwords are generated on your device using the browser's cryptographic random number generator (crypto.getRandomValues), the same class of randomness used for security keys. Nothing is sent to a server, logged, or stored. Reload the page and the password is gone.

What makes a strong password

  • Length matters most. Aim for 16 characters or more.
  • Mix character types: upper, lower, numbers and symbols widen the search space.
  • Use a unique password per site, and store them in a password manager.
  • The strength meter shows estimated entropy in bits. Above 90 bits is very strong.

Look-alike characters

Turn on "Exclude look-alikes" to drop characters that are easy to confuse when typing or reading aloud, such as the capital I, lowercase l, the digit 1, capital O and zero.
