Why Face ID / Code Noryo may be requested
Updated on 26 August 2026
Why Noryo sometimes asks for Face ID or your Code Noryo, what it checks, and why it protects your account.
Noryo may sometimes ask for Face ID or your Code Noryo, for example to confirm that it is really you on a device you already use, or to approve a sign-in request. Here is what this checks and why it protects your account.
On a device you already use
On a device already linked to your account, Face ID unlocks that device's cryptographic key. It uses only your biometrics, never your iPhone's unlock passcode. It is a presence layer added to owning the device: holding the device, plus proof that it is really you.
The Code Noryo is a code specific to the app, verified by our servers. It acts as a fallback to biometrics: if Face ID is not available, you enter this code instead.
Face ID alone is never enough
Face ID is never proof on its own. On a new or unknown device, it grants no recovery or access right. So no one can get into your account by presenting only a face on a device you have never used.
When you approve a request from an already-connected device, that approval signs a proof with the device's secure key (Secure Enclave). A device that has been revoked, lost, or had its key removed cannot approve.
