Frequently Asked Questions

How secure are the generated passwords?

Passwords are generated using the browser's built-in cryptographically secure random number generator (crypto.getRandomValues). This is the same standard used by security-focused applications.

What password length should I use?

For most accounts, 16 characters with mixed character types provides strong security. For high-value accounts (banking, email), use 20+ characters. For encryption keys, use 32+ characters.

Are my passwords stored anywhere?

No. Passwords are generated entirely in your browser and are never sent to any server. Once you close the tab, the passwords are gone.

What makes a password strong?

A strong password combines length (12+ characters), character variety (uppercase, lowercase, numbers, symbols), and randomness. Avoid dictionary words, names, or predictable patterns.
