Password Strength Checker

Estimate how long a password would take to crack by guessing

Checked here, never stored or sent anywhere.

How strength is judged

Length is the single biggest factor. This tool counts the character set a password draws on, works out the number of possible combinations, and turns that into a guessing time. It is a guide, not a verdict: a password that is long but is a known phrase is weaker than it looks.
