About this tool
Password strength plays a key role in protecting online accounts from unauthorized access. Short or predictable passwords are easier to guess, reuse, or break through automated attacks. This password strength checker helps you understand how secure a password is before you use it.
The checker evaluates several basic factors, including password length, the use of uppercase and lowercase letters, numbers, symbols, and common patterns. Based on these factors, it provides a simple strength level along with practical suggestions for improvement.
All analysis is performed locally in your browser. The password you enter is never uploaded, stored, or logged in any way. As soon as you close or refresh the page, the input is discarded.
While this tool can help identify weak passwords, it is still recommended to use unique passwords for each account and store them securely using a trusted password manager when possible.
