Frequently Asked Questions

Is my password sent anywhere?

No — your password is evaluated entirely in your browser. It is never transmitted or logged.

What makes a password strong?

Length (12+ chars), a mix of uppercase, lowercase, numbers, and symbols, and avoiding dictionary words or common patterns.

What does the crack time estimate mean?

It estimates how long a modern computer performing a brute-force attack would take to guess your password.

Should I type my real passwords here?

We recommend testing passwords of a similar pattern rather than typing actual passwords into any online tool.
