Password Security Best Practices

Unique Passwords: Use a different password for each account to prevent credential stuffing attacks. Never reuse passwords across multiple platforms or services.

Password Managers: Store passwords in a reputable password manager like Bitwarden, 1Password, or LastPass. This allows you to use complex passwords without memorizing them.

Two-Factor Authentication: Enable 2FA whenever available. Even if your password is compromised, 2FA provides an additional security layer to protect your accounts.

Regular Updates: Change passwords periodically, especially after data breaches. Monitor breach notifications and update affected passwords immediately.

Frequently Asked Questions

How secure are the generated passwords?

Our passwords use cryptographically secure random generation through your browser's crypto.getRandomValues() API. This ensures true randomness and maximum security against brute force attacks.

What is custom input transformation?

This feature converts your personal input (like names or words) into strong passwords using character substitution, randomization, and enhancement techniques while maintaining some connection to your original input.

Are my passwords stored or transmitted?

No. All password generation happens locally in your browser. Nothing is stored on our servers or transmitted over the internet, ensuring complete privacy and security.

What password length should I use?

We recommend at least 12-16 characters for most accounts. For high-security accounts (banking, email), use 20+ characters. Longer passwords provide exponentially better protection against attacks.
