# Feature Description



Biometric Based Authentication allows users to authenticate UPI transactions using device-supported biometrics such as Fingerprint or Face Recognition instead of entering MPIN. This feature improves user convenience and provides a faster and more seamless transaction experience.

The feature includes:

* Checking bank support for BioAuth
* Verifying account eligibility for biometric authentication
* Enabling or disabling BioAuth for accounts
* Handling user consent for BioAuth activation
* Supporting transaction authentication using Biometrics or MPIN

BioAuth eligibility and consent details are received through account APIs, allowing the application to determine whether biometric authentication can be enabled for a specific account. Once enabled successfully, users can authenticate supported transactions using biometrics on eligible devices.

The feature is supported on both Android and iOS platforms with the required platform-specific configurations.
