What is this tool?
Generates a secure random password and separately checks the strength of an existing password against common weakness patterns.
How to use it
Use the generator to create a new password with your chosen length and character types, or paste an existing password into the checker to see its estimated strength.
A strength checker can only evaluate patterns, not whether a password has already been leaked in a data breach — using a unique password for every account matters at least as much as the password's raw complexity.
