Check Your Password Strength

This tool analyzes your password to estimate how resistant it is to guessing or brute-force attacks.

We check for several factors that increase entropy (randomness):

Length: Passwords under 8 characters are easily cracked. Aim for 12+.
Variety: Using a mix of uppercase, numbers, and symbols vastly increases the number of possible combinations.

Note: This check runs entirely in your browser. We do not store or transmit your password.
