Frequently asked questions

Is it safe to type my real password here?

The check happens only in your browser and nothing is sent anywhere. Even so, avoid testing a password you are actively using on shared or untrusted devices.

How is strength estimated?

It looks at length, the variety of character types and common weak patterns to produce a rough strength score. It is guidance, not a guarantee.
