Frequently asked questions

How long should my password be?+

Minimum 12 characters for normal accounts. 16+ for email, banking, or anything financial. 20+ for crypto wallets and admin accounts.

Is `crypto.getRandomValues` actually random?+

Yes — it's cryptographically secure (CSPRNG), as opposed to `Math.random()` which is predictable enough to attack.

Are generated passwords logged?+

No. They're created in your browser and never sent anywhere. Refresh the page and they're gone.
