App-to-app signing

The App-to-App feature gives users with activated accounts the ability to approve a pending request from a third-party application or webpage with their mobile device.

To approve an app-to-app request

The feature follows this workflow for approving a transaction initialized by another application:

1. An external, third-party application or web page requests approval on a transaction from the user.

2. The operating system makes the call to open the transaction using Mobile Authenticator Studio.

3. The splash screen of the Mobile Authenticator Studio app is displayed.

4. The user reviews the request details and taps Approve to continue the process.

5. The user is required to confirm their identity using OTP or biometric authentication.

6. The user is returned to the external, third-party application confirming the request approval.

There is an additional scenario:

• If the user does not want to approve the transaction, they can tap Cancel or Deny to exit the approval process.
