Password Strength Checker: Test and Improve Your Password Security
Why Check Password Strength?
Weak passwords are one of the most common causes of account compromise. A strength checker helps you see—in real time—whether a password meets basic security criteria before you use it on a new account or update an existing one.
The XSular Password Strength Checker runs entirely in your browser. Your password is never uploaded, stored, or logged. Analysis happens locally on your device.
How the Checker Works
Enter any password to see a strength meter, estimated crack time, and a checklist of criteria such as length, mixed case, numbers, special characters, and avoidance of common patterns like "password" or "123456".
Use the Generate button to create a strong random password, or follow the suggestions to improve a password you are already considering. Always use unique passwords for each account and store them in a reputable password manager.
