About Password Strength Checker

This tool analyzes your password across eight security dimensions: length, lowercase letters, uppercase letters, numbers, special characters, repeated patterns, common sequences, and dictionary words. Each criterion contributes to a score out of 100.

You can also use the Generate button to instantly create a cryptographically random 16-character password that satisfies all criteria. Click Copy to put it on your clipboard.

Everything runs entirely in your browser. Your password is never sent to any server, making this tool completely private and secure.
