What these checks mean

This is a basic pattern check. It looks for short length, repeated characters or blocks, and some common words and sequences. Passing these checks does not establish that a password is secure or unique.

The tool does not estimate entropy or cracking time, and it does not query a breach database. The way a password was chosen matters more than its visible character mix.

Generate a long random password for each account with the Password Generator and save it in a password manager.
