Password Strength Checker
See whether a password is Weak, Fair, Good, or Strong. The score is a guide, not a guarantee against every attack.
Weak
- Enter a password to check.
Your password is checked in this session and is not stored, logged, or saved to LocalStorage.
What is a password strength checker?
It estimates how hard a password is to guess from length, variety, and obvious patterns. It does not test whether the password has appeared in a public breach.
How to use it
- Type or paste a password.
- Read the rating and the notes.
- Adjust until the rating is Strong, then store it in a password manager.
FAQ
Is my password uploaded to an API?
No. It is scored in this application session and discarded. It is not written to a database or analytics product.
Why can a long passphrase still be Fair?
If it uses only lowercase letters, the checker asks for more variety. Add capitals, numbers, or symbols, or generate a new password.
Read the original guide: See whether the password is weak before the form accepts it.
