Password Strength Calculator: How Long to Crack Your Password?

Type in the shape of a password (not the password itself) and we will estimate how long a determined attacker with modern hardware would take to guess it by brute force.

This estimates brute force only: trying every combination. It assumes a truly random password of the length and character set you pick. Real passwords based on words, dates or patterns fall far faster to a dictionary attack, which is what the honesty box reflects. Never type a real password into any website, including this one.
