Analyze the complexity of your password completely offline.
The Zadein Password Strength Checker evaluates a password against common security criteria and gives a clear strength rating. It checks length, character variety, and common patterns to help you understand how secure a password is.
Length is the most important factor, followed by using a mix of uppercase, lowercase, numbers, and symbols, and avoiding common words or patterns.
No. Password analysis happens entirely in the browser. Your password is never transmitted or stored.
A high score indicates the password is resistant to brute-force attacks. It does not protect against phishing, data breaches, or reuse across sites.
