Type your password into the Password Strength Checker. It analyzes length, character variety, and common patterns, then displays a strength meter with specific feedback on how to improve it.

What makes a password strong?▼

A strong password has at least 12 characters, includes uppercase and lowercase letters, numbers, and symbols, avoids common words and patterns, and is unique across different services.

Should I use a password manager?▼
