Password Generator

Why Use a Strong Password Generator?

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.

What is Password Entropy?

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.

How Long Does it Take to Crack a Password?

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.

Password Security Best Practices

• Use a unique password for every account
• Store passwords in a trusted password manager
• Enable two-factor authentication (2FA) where available
• Never share passwords via email or messaging apps
• Change passwords immediately if a breach is suspected
