8. Add multiple fingerprints to use Touch ID conveniently
You can have multiple fingers set ups to use Touch ID conveniently.
Go to the settings and tap Touch ID & Passcode. Then under fingerprints, select the option named Add a Fingerprint. The final step would be to tap on the fingerprint you just created where you need to enter a proper name. You can name it like the right thumb or left thumb so that you can remember which fingerprint is needed to set up again if you face any problem.
