🔒 Password Strength Checker

Quickly estimate password strength with visual feedback and tips.

Password Strength Checker

Test the strength of your password instantly. This tool checks for length, character variety, and complexity, and provides a simple visual indicator of strength.

Enter password:

Strength

Strong

Tip: use 12+ characters, mix uppercase, lowercase, numbers, and symbols for best security.

How to use this tool

Paste or type a password into the field to see the live score.
Review the color-coded meter and feedback to decide whether to strengthen it.
Copy or download the evaluated password once it meets your requirements.

What we check

Length milestones at 8 and 12 characters to encourage stronger defaults.
Presence of lowercase, uppercase, digits, and symbols for character diversity.
Simple heuristics that mirror many corporate password policies.

Improve weak passwords

Add random words or phrases instead of predictable substitutions.
Avoid repeating characters or keyboard patterns like '1234' or 'qwerty'.
Use the Password Generator tool when you need a high-entropy alternative.

FAQ

Is this a full security audit?: No. It provides quick heuristics. Real strength also depends on entropy, breaches, and reuse history.
Do you store my password?: Never. All checks run in your browser, and nothing is transmitted to any server.
Why did a strong password still score low?: If it lacks certain character classes or length thresholds, the heuristic score remains conservative. Add more variety to improve it.
