Check Password Strength Instantly

Estimate password strength locally with tips to improve it

This is a relative strength estimate for guidance only. It does not guarantee that a password cannot be guessed or cracked.

About This Tool

Password Strength Checker estimates how strong a password looks based on length, character classes, and simple pattern penalties. It runs entirely in your browser and never uploads the password. Results are relative guidance — not a promise of absolute security.

How to Use

  1. Type or paste a password
  2. Review the score and level
  3. Check which criteria are met
  4. Follow the suggestions to improve it
  5. Clear when you are done

Common Use Cases

  • Test a new password before saving it
  • Teach teammates about stronger passwords
  • Audit password policy ideas
  • Compare short vs long passphrases
  • Avoid weak patterns like 123456

FAQ

Q1: Is my password uploaded?

No. Strength checks are processed locally in your browser.

Q2: Does a high score mean unbreakable?

No. Scores are relative. Even strong passwords can be compromised via phishing or leaks.

Q3: What improves the score?

Longer length, mixed character types, and avoiding repeated or obvious sequences.

Q4: Should I use this instead of a password manager?

No. Use a password manager for unique passwords; this tool only estimates strength.

Q5: Are common passwords detected?

Some common patterns are penalized, but the list is not exhaustive.
