# Face Authentication

During Enrolment, a user's facial image (selfie) is captured and saved in your systems. This saved image can later be used for various purposes: authentication, transaction verification, or account resets.

* **Authentication**: For logging in, users capture a fresh selfie, which is then compared with the saved facial image. If both images match, the user is granted access to your services.
* **Transaction Verification**: When users initiate actions like bank transfers, they are prompted to take a selfie. Upon a match with the stored image, the transaction proceeds.
* **Account Resets**: If users forget their password, they can opt to reset it by providing a selfie. A match with the saved face image allows them to set a new password.

The flow diagram below shows the participants of the use case and the data flow:
