Biometric authentication

Definition

Identity verification using a physical characteristic such as a face or fingerprint. On Apple devices, apps receive an authentication result rather than raw biometric data.

Why it matters

Understanding this term helps you compare security options and choose the right recovery plan without relying on marketing claims.

Practical tip

Keep recovery information separate from the device or vault it is meant to recover, and test your setup before you need it.
