How does signing in with my face work?

A typical sign-in takes under a minute:

• Open the app or site you want to use and choose sign-in. A QR code appears on screen.
• Scan the code with the SenseCrypt app on your phone.
• Your phone shows exactly what you're approving — which app, which request.
• Glance at your phone. A live face check runs on the device itself.
• You're in. Nothing was typed, so there's nothing a phishing page could have collected.

The face match and liveness check run on your phone — your face never crosses the network. Only a single-use cryptographic token does.
