Frequently Asked Questions
What makes a strong password?

Use at least 12 characters mixing uppercase, lowercase, numbers, and symbols. Avoid dictionary words, names, or dates. This generator uses the Web Crypto API for true randomness.

How long should a password be?

12 characters minimum for personal accounts, 16+ for financial, 20+ for admin. Length matters more than complexity.

Is this generator safe to use?

Yes — runs entirely in your browser. No passwords are sent to any server or stored anywhere.

How often should I change passwords?

Only when you believe they are compromised. Using a unique password for every site matters more than frequent changes.

What is a passphrase?

A sequence of random words like correct-horse-battery-staple. Passphrases are easier to remember and equally secure with 4+ random words.
