Frequently Asked Questions
How long should my password be to be secure?▼
At minimum 12 characters, but 16+ characters is recommended. Each additional character exponentially increases the time needed for brute-force attacks. A 12-character password with mixed character types would take centuries to crack with current technology.
Is a random password better than a passphrase?▼
Both can be secure. A random 16-character password (e.g., 'xK9#mP2$vL7@nQ4&') is compact but hard to remember. A passphrase of 4-5 random words (e.g., 'correct-horse-battery-staple') is easier to remember and equally strong. Choose based on whether you use a password manager.
Are the generated passwords truly random and secure?▼
Yes. This tool uses the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure random numbers. The randomness comes from your operating system's entropy sources, making the output unpredictable and suitable for security-sensitive use.
