Frequently asked questions
- Is the password sent anywhere?
- No. It is generated on your device with crypto.getRandomValues and never leaves the page. Still, generate passwords on a device you trust.
- What length should I use?
- 16+ characters with mixed sets gives well over 90 bits of entropy, which is comfortably strong for almost any account.
