🔒 Security

Passwords are generated using:

window.crypto.getRandomValues()

This cryptographically secure API provides significantly stronger randomness than:

Math.random()

• ✅ Passwords never leave your device
• ✅ No API requests
• ✅ No hidden tracking
• ✅ No password storage
• ✅ No analytics related to generated passwords
