How to Check Password Strength Online — Free Tool
Strong passwords resist guessing and cracking. Before you roll out a new credential or advise users, estimate strength with length, character variety, and common-pattern checks. XSular’s password checker scores input in real time in your browser—nothing is sent to our servers— and includes a generator when you need a better alternative.
Type or paste the password
Enter the password in the field below (toggle visibility if you need to confirm characters). Analysis starts immediately: length, uppercase, lowercase, numbers, symbols, and repeated patterns all feed the score.
What you'll see Screenshot: Password field with masked dots and a strength meter bar filling from red toward green as characters are added.
Review the strength meter and crack-time estimate
The meter summarizes overall strength from weak to strong. A crack-time estimate gives intuition for offline attacks. Read the checklist below the field for missing requirements—e.g. no symbol or too short.
What you'll see Screenshot: Strength label Strong, estimated crack time, and checklist items with checkmarks for length and mixed case.
Generate a stronger password if needed
Use the built-in generator to create a random password with your chosen length and character sets. Copy it to your password manager; never reuse generated passwords across sites.
What you'll see Screenshot: Generate button and a high-entropy password displayed with copy icon and character-type toggles enabled.

Strength tools are guidance, not guarantees—enable MFA where possible and store secrets in a password manager. This checker helps you avoid obvious mistakes; pair it with your organization’s policy on minimum length and banned common passwords.
