Generate ultra-secure passwords with entropy scoring, crack time estimation, and visual strength meter.
Weak passwords are the leading cause of account breaches. A strong password should be at least 12 characters long, include uppercase, lowercase, numbers, and symbols, and must never be reused across sites. SECURION generates cryptographically secure passwords using your browser's built-in random number generator — no passwords are ever transmitted or stored.
Entropy measures the unpredictability of a password in bits. The higher the entropy, the harder it is to crack. A password with 50 bits of entropy takes far longer to crack than one with 28 bits. For modern security, aim for at least 80 bits of entropy. SECURION shows your password's exact entropy based on character set size and length.
A modern GPU can try billions of passwords per second in an offline attack. An 8-character password with only lowercase letters can be cracked in seconds. A 16-character mixed-character password with 100+ bits of entropy would take trillions of years to brute-force. Always use passwords of 16+ characters for sensitive accounts.
