Check how strong your password really is and get tips

Clacify's Password Strength Meter analyses your password's strength based on length, character variety (uppercase, lowercase, numbers, symbols), and common patterns (dictionary words, keyboard sequences, repeated characters). It shows an estimated time to crack using modern brute-force methods and gives specific tips to improve weak passwords. All analysis happens locally — your password is never sent to any server.
A strong password: 12+ characters long, mix of uppercase+lowercase+numbers+symbols, no real words (dictionary words are cracked in seconds), no personal info (name, birthday, pet name). A 12-character random password with all character types would take centuries to crack; a simple 8-letter word takes milliseconds.
'password' — instantly. 'P@ssword1' — seconds. 'Tr0ub4dor&3' — centuries. A 12-character truly random mix of all character types — millions of years on current hardware. The most important factor is length — each additional character exponentially increases crack time. Use a password manager to generate and store long random passwords.
