Biometric Authentication

Biometric authentication is the way by which user authenticates into the mobile application using their device’s biometric option such as Fingerprint or Face ID. This mode of authentication can be used in addition to the usual way of login using email and password. Biometric authentication eliminates the need for typing the lengthy email and password every time you get signed out of the app, thereby improving the accessibility of the app.

For enabling biometric authentication for the mobile app, user needs to activate Face ID/Touch ID/Fingerprint security by adding their Face ID/Fingerprint via device settings. Please refer to your device manual on how to set up the fingerprint/face ID/Touch ID.

Once you have logged in to the application, you can see a ribbon stating “Enable Biometric Authentication” with a toggle button. If you switch on the toggle, you will be shown with the below popup to enable biometrics at device level if you haven’t enrolled for it. Once opted in, the Enable biometric authentication ribbon will be hidden.
