A free Password Strength Checker analyses your password for length, character variety (uppercase, lowercase, numbers, symbols), and common patterns to give a real-time strength rating from Weak to Strong. Unlike basic checkers, it highlights exactly which improvements to make. All checking happens in your browser — your password is never sent to any server, making it completely private and safe to use.
