View the strength analysis
The tool rates your password as weak, fair, strong, or very strong. It considers length, character variety, common patterns, dictionary words, and known compromised passwords.
Review the estimated crack time
See how long it would take to crack your password using different attack methods: online brute force, offline fast hash, and offline slow hash. Strong passwords should take years or more.
Improve your password
Follow the specific suggestions provided: add more characters, include special symbols, avoid dictionary words, or remove common patterns. Re-check until you achieve a "very strong" rating.
Pro Tips
- Length is the single most important factor in password strength. A 16-character password is exponentially stronger than an 8-character one.
- Avoid common substitutions like p@ssw0rd — password crackers check for these automatically.
- A random passphrase of 4-5 words (e.g., "correct horse battery staple") can be both strong and memorable.
Common Issues & Fixes
Issue: My password is marked as weak despite having special characters.
Fix: Special characters help, but short passwords with simple patterns are still weak. Increase the length to at least 12 characters and avoid dictionary words.
Issue: Is it safe to enter my real password into this tool?
Fix: This tool processes everything locally in your browser. Your password is never transmitted over the network. However, never enter passwords into tools you do not trust.
