In my app, how can I confirm it’s me using notifications to my phone or tablet?
When you're asked to confirm it's you, you'll get a notification on your app. Tap it and follow the instructions. You'll be asked to confirm it's you. Once you've done this, you'll be able to complete what you were doing.
If you don't have your notifications switched on, you can find it by logging into your app and tapping on the bell icon on the homepage.
