Mobile Biometrics

Login users with native mobile biometrics. This process relies on the device ability to leverage built-in biometric sensors. To support mobile biometrics in the app, first implement the SDK call that creates an authenticator (cryptographic key-pair) on the end-user device and then register this authenticator with Transmit. The private key remains securely stored on the device and protected by biometrics, while the public key is registered with Transmit for a given user. To authenticate, the device uses mobile biometrics to access the private key and to sign a challenge that gets verified by Transmit. Note: registration and authentication are two-step procedures that start by calling the client-side SDK provided by Transmit, and complete using these APIs.
