# Password Strength Checker

> Estimate how long a password would take to crack, and see exactly what weakens it.

To check password strength, type it above and the tool estimates entropy from length and character variety, then converts that into an offline crack time. Analysis runs entirely in your browser and the password is never transmitted, logged or stored.

### Is it safe to type my real password here?

The analysis is pure client-side JavaScript with no network request, so nothing is sent anywhere. Even so, the safest habit is to test a password of the same shape rather than the exact one you use.
