About
Analyze password strength based on length, character sets, and estimated entropy.
What is checked
The checker evaluates password length, character variety, and approximate entropy to provide a practical strength score.
How to improve weak passwords
Stronger passwords are typically longer and combine uppercase, lowercase, numbers, and symbols. Avoid predictable patterns and reused credentials.
Important security note
This tool estimates strength locally in the browser. It does not replace breach checks, MFA, or account-specific security policies.
