Password Strength Checker

Quickly assess password resistance to guessing and brute-force.

Sensitive processing stays in your browser whenever possible.

Details

Strength scoring considers length, character diversity, and common weak patterns so weaknesses are visible before policy rollout or user training.

This tool does not replace a password manager or server-side controls; it is a training aid and quick assessment helper.

Input

Passwords built only with letter/number substitutions are usually weaker than users think.
Long random passphrases are often both stronger and more memorable than short complex passwords.
Never paste real production passwords into untrusted public tools.
