Password Strength Details
| Name | Password Strength |
| Type | Security |
| Description | A password strength analyzer evaluates how secure a password is by calculating its entropy (measured in bits). Entropy is determined by the password length and the variety of character types used. Higher entropy means a password is harder to crack through brute-force attacks. This tool analyzes passwords entirely in your browser - nothing is sent to any server. |
