Password Strength Checker
Type a password to check how strong it is. See a detailed breakdown of security criteria.
What Makes a Strong Password?
A strong password is long, complex, and unpredictable. It should combine uppercase and lowercase letters, numbers, and special symbols. Avoid common patterns like "123", "abc", "password", or "qwerty" which are easily guessed by attackers.
