About Password Strength Checker
The password strength checker analyzes any password and scores it based on length, character variety, and common-pattern detection.
Understanding what makes a password weak — short length, single character class, dictionary words — helps anyone build habits that keep accounts safe. This tool grades input in real time with suggestions for strengthening it.
When to Use Password Strength Checker
Use it before choosing a new password, to demonstrate safe password habits to staff, or to audit the strength of a candidate password.
Pro Tip
Length dominates strength: a 16-character passphrase beats a 12-character random mix in real-world attack math.
