Free online password strength checker tool to evaluate security and improve weak passwords.

How it works

Password Strength Checker evaluates length, complexity, and common pattern exposure to estimate crack resistance. It is useful for policy tuning and user education during sign-up flows. Treat the score as guidance and combine it with breach checks and MFA.

Example

Input:
password123

Output:
Weak (common pattern)

FAQ

Is complexity more important than length?

Length is usually the biggest factor, while complexity helps avoid predictable patterns and dictionary-style guesses.

Does a strong score guarantee account safety?

No. Security also depends on MFA, breach monitoring, unique passwords, and secure account recovery flows.
