PasswordStr Strength Check

Score any password in real time. Entropy, variety, and common-pattern checks.

PasswordStr analyses any password and gives it a security score out of 100. It checks length, uppercase and lowercase letters, digits, symbols, entropy bits, and common pattern matches, then explains every point deducted or earned. A colour-coded strength label — Very Weak to Very Strong — makes the verdict instant. A built-in generator creates random passwords to a length you choose. Nothing you type is stored or transmitted.
