How to Protect iPhone Apps with Touch ID | Simple steps

Unlocking your iPhone, iPad, or using Touch ID  is a more convenient way than entering a password or passcode each time. It’s good for users who always forget passwords. Therefore, Apple’s Touch ID is a welcome addition to the existing security features. The Touch ID can also be used to add another level of security to your sensitive apps. Turning on the Touch ID in your Banking app or Paypal app will not only make it easier for you to open it, it will also make sure that only you can unlock it with your fingerprint. This short tutorial will outline basic Touch ID definitions, initial setup, unlocking your apps, and how to use them.

What is the Touch ID?

Apple’s Fingerprint Identity Sensor so-called Touch-ID is another security layer for iPhone users that uses biometric authentication to unlock devices and apps. It’s a great alternative to the old way to unlock apps and devices with a password. If you forget your password for your iPhone or iPad, we recommend that you use Touch ID instead. With the Touch ID, you can unlock your device or apps using your fingerprint. Although your fingerprint is unique, the Touch ID is still not as strong as a good alphanumeric password. However, if you usually want to quickly unlock your device, Touch ID can be a good complement to a strong password. It is primarily intended for ease of use, not security. Make sure you enter your device password in one place if you need it.

Touch ID uses the iPhone or iPad fingerprint scanner to work. This scanner is located in the Home button on your phone. As you probably already know, the Home button has a number of important but profound features, such as wake up the system, return the screen you are on to the home screen, and of course host the fingerprint scanner or touch ID sensor. The Home button is made of scratch-resistant sapphire crystal that protects the fingerprint sensor and a steel ring around the sensor. Touching this ring with your finger or thumb causes the capacitive touch ID sensor to pick up a high-resolution image of your fingerprint. If you have already registered this fingerprint, The Touch ID sensor compares this fingerprint image with the data stored in the memory of your device and unlocks the device during authentication. Apple claims that the more you use the Touch ID, the better it will be to recognize your fingerprint as it works from different angles over time.

Why would Touch ID automatically disable

There are five situations in which the Touch ID is automatically disabled. They should protect your identity and your data. These include the following:

  1. If left unused for 48 hours, the Touch ID will be disabled and you will need to enter your password or password to re-enable it.
  2. After restarting or resetting the device, you must re-enter the passcode or password to enable the Touch ID.
  3. After 5 unsuccessful attempts to use the fingerprint to unlock your device one at a time, you will need to enter your passcode or password to re-enable it.
  4. If a remote lock was sent from Find My iPhone or Find My Mac, you’ll need to enter your passcode or password to reactivate it.
  5. If your passcode was not unlocked within six days and Touch ID was not unlocked within six hours, you’ll need to enter your passcode or password to re-enable it.

How to activate the Touch ID on your device

Starting with the iPhone 5S, which has been released in Since 2013, Touch ID is an integral part of iPhones. The iPhone 8 and iPhone 8 Plus still have this security feature today, although the iPhone X no longer supports it. Instead, the iPhone X uses the face ID to unlock itself.

If you have an iPhone 5S, an iPhone 6, or a variant, iPhone 7 or its variants, or iPhone 8 and iPhone 8 Plus, you must register a fingerprint for the Touch ID for the initial setup. You should be able to add five more fingerprints later, for example: From your family members or friends.

  1. Open the Settings app.
  2. Tap Touch ID & Passcode.
  3. Enter your passcode for authorization when prompted. (To set up the Touch ID first, you must first enter a passcode. Store this passcode in one place so that you have a backup method to unlock the phone if the Touch ID fails.)
  4. Touch Add a fingerprint button.
  5. Place the finger you want to register on the Home button and leave it there until you feel a humming sound.
  6. Lift your finger and put it back down. Repeat every time you feel a buzz.
  7. Tap Next when Touch ID notifies you that the first step has been completed and peripheral data is now required.
  8. Place the finger edges you want to register on the Home button and leave them there until you feel a humming sound.
  9. Lift your finger and put it back down. Repeat the process with a different edge until you have registered the entire surface of your finger.
  10.  Tap Continue .

The same steps can be repeated for additional fingers that you can add later.

After successfully setting up the Touch ID, you can activate the Touch ID.

    1. Open the Settings app.
    2. Select Touch ID and Password .
    3. Enter your password to continue.
    4. Enable the Touch ID for one or more of the following options:
      • unlock iPhone
      • Apple Pay (for iPhone 6 and 6 Plus or higher)
      • iTunes & App Store

To unlock Apps with Touch ID

Not all apps in your iPhone support the Touch ID. Some do not need a lock at all, while others need it. If you want to enable the Touch ID in the app, first find out if the app supports it. In almost all apps that support the Touch ID, you’ll find the option to set up in app settings. After you identify the app for which you want to enable the Touch ID lock, you can do the following:

  1. Open app
  2. Go to the settings menu.
  3. Search for Passcode and Touch ID function or similar. The wording should suggest something similar.
  4. Activate the passcode setting and select a passcode.
  5. Enable or enable Touch ID and enter your passcode when prompted.
  6. You can now use the Touch ID to unlock the app.

So use the Touch ID to buy things

With the Touch ID, you can shop at the iTunes Store, App Store, and iBooks Store. How to do it:

  1. Make sure iTunes & App Store is turned on in Settings> ID and Passcode. If you can not turn it on, you’ll need to sign in with your Apple ID under Settings> iTunes & App Store.
  2. Open the iTunes Store, the App Store, or the iBooks Store.
  3. Tap something to buy. You will see a prompt for the Touch ID.
  4. To make a purchase, lightly touch the Home button.

With iPhone 6 or higher, Touch ID should use Apple Pay to pay for items in the iTunes Store, App Store, iBooks Store, apps, and some websites that you access through Safari.
