Biometric Authentication

Authentication

Unlocking with your face, fingerprint, or similar.

Definition

Biometric authentication uses a body feature—like a fingerprint or face scan—to confirm it’s you.

In plain English Unlocking with your face, fingerprint, or similar.

Why this matters

Why it matters: It can be convenient and secure, but biometric data is sensitive and can’t be “changed” like a password.

Example

Example: Unlocking your phone with Face ID or a fingerprint.
