If my phone is lost or stolen, can anyone log in to the app using an image of my fingerprint?
You should let us know so we can suspend your mobile banking app.
Have you met Cora, your digital assistant?
Cora can help you with a wide range of queries, including this one.
You also need to tell your mobile phone network provider immediately so they can disable the service to your phone. If you have the 'Find my iPhone' enabled then you can remotely wipe your iPhone via iCloud.
