So before we proceed lets first know what Touch ID is and how it works? So Touch ID is basically a fingerprint identity sensor and Apple has named it  Touch ID which can be used for biometric authentication to unlock a device as well as apps. It is better than remembering a password to unlock your device. But if you tend to forget passwords then we would suggest you to use Touch ID instead. As already said you do not need to enter a password you can just unlock your device or app using your fingerprint because everyone has a unique fingerprint. However, it is a faster way to unlock your device but not as safe as a password. It can be used at your convenience but not for security purposes Also, it gets automatically turned off in various situations such as if left unused for 48 hours in that case you are required to enter passcode or password to enable it again. Secondly, after you reboot or reset your device again you need to enter your password to enable it. Thirdly after five failed attempts in a row, if a remote lock has been sent via Find my iPhone or Find my Mac and when the user has not used passcode to unlock the device in six days.  Here is Guide how you can enable Touch ID on iPhone or iPad Before you set up Touch ID, you need to create a password for your device. To enable it, go to Touch ID and Passcode. Then turn password on, now enter a  six-digit passcode or else you can switch to a four-digit numeric code, a custom numeric code, or a custom alphanumeric code. Lastly, enter your passcode again to confirm it and activate it. Then follow these steps:

Before setting up make sure that the Home button and your finger are clean and dry. Tap on Settings > Touch ID & Passcode, now enter your passcode. Then tap on Add a Fingerprint and hold your device as you normally would when touching the Home button. Don’t press just touch the Home button with your finger. Lift your finger when you feel a quick vibration, or until you’re asked to. Continue to lift and rest your finger slowly, making small adjustments to the position of your finger each time. The next screen asks you to adjust your grip. Hold your device as you normally would when unlocking it, and touch the Home button with the outer areas of your fingertip, instead of the centre portion that you scanned first. You can also try another finger if you have trouble enrolling one finger.

How to enable Touch ID to unlock your iPhone or make purchases The touch ID can be used instead of a password to make purchases in the iTunes Store, App Store, and Apple Books. Follow the steps to know how to enable it:
