The Random Password Generator uses cryptographically secure random numbers to create unguessable passwords. Customize password length and character types, with real-time strength assessment. All passwords are generated locally - they're never transmitted over the network.

Why You Need Strong Passwords

Weak passwords are the primary cause of account breaches. Simple passwords like '123456' or 'password' can be cracked in seconds. Hackers use dictionary attacks and rainbow tables to crack common password patterns. Only truly random passwords can effectively resist these attacks.

What Makes a Strong Password?

  • Length: At least 12 characters recommended, 16+ is better
  • Character diversity: Include uppercase, lowercase, numbers, and symbols
  • Avoid patterns: Don't use consecutive characters (abc, 123) or repeated characters (aaa)
  • Uniqueness: Use different passwords for different sites

Password Security Tips

Use a password manager to store complex passwords, so you only need to remember one master password. Enable two-factor authentication (2FA) for an extra layer of security. Change passwords regularly and never reuse passwords across different services.

FAQ

Q: How is this more secure than making up my own password?

A: Humans are bad at creating truly random passwords - we tend to use patterns (like replacing letters with similar-looking numbers) that hackers know well. This tool uses browser's crypto.getRandomValues() which provides true randomness that cannot be predicted or guessed.

Q: How long should my password be?

A: Longer is better. A 12-character password is the minimum for security-sensitive accounts. 16 characters is recommended, 20+ is ideal. Each additional character exponentially increases the time needed to brute-force crack.

Q: Why exclude similar characters?

A: Characters like I (uppercase i), l (lowercase L), 1 (one), O (uppercase o), and 0 (zero) look very similar in many fonts. Excluding them prevents confusion when manually typing passwords, especially from printed materials.
