Password Strength Tester

This weekend I put together a simple password strength tester. You can try it out here.


  • Simple interface.
  • Open source (MIT licensed).
  • Easy to inspect. The interface code is contained in a single, <300 line JavaScript file.
  • Self-contained. No external connections for assets, social media sites, analytics, etc.
  • Can be run offline (no internet connection) or locally (by downloading an archive of the the Git repository).

Built with:

  • zxcvbn: JavaScript password strength estimator.
  • Bulma: Open source CSS framework.
  • font-awesome: Open source font icons.
