Question 1 of 23 about Touch ID/ Fingerprint Scanner
What are Touch ID and Fingerprint Scanner?
They’re both services that let you log in to apps using your fingerprint (Touch ID on Apple, Fingerprint Scanner on Android devices). Once you’ve registered your fingerprint on your device, you can sign in by touching your finger or thumb on the home button.
If the scan matches your profile, your device will unlock. You can use your passcode instead, if you want to.
