Password Security Best Practices

Essential Password Guidelines

Use unique passwords for each of your accounts
Longer passwords (12+ characters) are generally more secure
Include a mix of uppercase, lowercase, numbers, and symbols
Avoid common words, personal information, or keyboard patterns

Advanced Security Tips

Consider using a password manager to store your passwords securely
Enable two-factor authentication when available
Regularly update passwords for sensitive accounts
Use our entropy calculation to verify password strength

How Our Password Generator Works

Cryptographic Security

Our password generator uses your browser's built-in cryptographically secure pseudorandom number generator (CSPRNG) to ensure maximum randomness and security. This is the same technology used by security professionals and cryptographic applications.

Entropy Calculation

Password entropy measures the unpredictability of a password. Higher entropy means a password is harder to crack. Our tool calculates entropy based on character set size and password length, helping you understand your password's true strength.

Privacy Protection

All password generation happens entirely in your browser using client-side JavaScript. No passwords are ever transmitted to our servers, logged, or stored anywhere. Your generated passwords remain completely private and secure.
