How to put a fingerprint on your iPhone

What is Touch ID on iPhone and iPad?

After learning how to check iPhone for originality, and performing a number of related simple manipulations, the owner of the device is likely to protect their confidential data, as well as facilitate the unlocking of the application menu. You can do both using Touch ID. What it is and how to set up the Touch ID correctly. let’s try to understand.

Touch ID is the default feature on Apple products, which allows you to unlock your iPhone or iPad with a single tap:

  • unlock your iPhone or iPad with a tap of your finger;
  • protect data on your phone and restrict access to certain apps or services;
  • make purchases from the App Store without entering your account password.

Touch ID’s principle of operation is simple. A mini-scanner built into the home button records the iPhone owner’s volumetric fingerprints during setup, and then checks the data against what’s in the database with subsequent touches. So an outsider, with an almost hundred percent chance of having a different set of fingerprints, simply can’t unlock the iPhone and use the information stored on it. including photos, audio and video recordings, email addresses, and so on.

Important: Touch ID does not unlock Apple ID, log in to iCloud and other proprietary online services. it is used on each device individually and protects your iPad or iPhone, not your account.

The Touch Idy sensor works on iPhones since 5S and iPads since Air 2; the second-generation sensors, which are more accurate and have a minimum number of “outliers,” are available starting with the iPhone 6S and iPad Pro 10, respectively.5. Since Touch ID is a physical and not a software device, owners of older iPhones and iPads will need to set up a passcode for security. it’s easier than unlinking an iPhone from an Apple ID.

How is Touch ID designed and how does it work?

There are currently two generations of Touch ID. They differ in the speed of reading data and consequently faster unlocking. The second generation has been available since iPhone 6S, and the unlock speed is actually faster there.

Touch ID sensor is built into the Home button and covered with a sapphire crystal. This protects the scanner from minor mechanical damage. Built-in sensor scans the fingertip and recognizes the pattern on it. In addition, it does not matter what angle you put your finger: top, bottom, side. the device is easily unlocked. You can add multiple fingers at once to unlock the device with either hand.

How to use Touch ID

And although you can’t count the number of scenarios where the fingerprint scanner is useful, even if you really want to, the mechanism of using Touch ID is always the same:

  • To unlock your iPhone or iPad, press the “Home” button and, without releasing your finger, go through the scanner. If the procedure doesn’t work the first time. you’ll have to clear either the button or the fingerprint;
  • When shopping on iTunes and the App Store. put your finger on when prompted on the screen;

How to add all 10 fingerprints to Touch ID on your iPhone or iPad

Even though Apple has been outfitting its flagships with Face ID for years, there are still plenty of smartphones with good old Touch ID. They support iOS 12 and don’t lose their relevance.

By default, you can add only five different fingerprints for unlock. But there is a little-known trick to increase the number to ten. The idea is to put two fingerprints in each of the available slots at once. Here’s how it’s done.

Open “Settings” → “Touch ID and passcode” and enter the PIN code.

Delete all prints by opening each one in turn and pressing the appropriate button.

Select “Add fingerprint” and apply your right thumb several times.

Then, when iOS asks you to hold the device comfortably, attach and scan your left thumb.

Repeat the process for all the other fingers.

As a result, you’ll be able to unlock your iPhone, use Apple Pay, fill out passwords, and install apps by touching Touch ID with any of the ten fingers.

Theoretically, registering two fingerprints in the same slot could reduce recognition accuracy. After all, each of them is deliberately recorded twice in different positions to eliminate scanning errors. But it works fine in practice.

If any problems occur, you can simply adjust the thumb as it should be and add the other two in each of the remaining four slots. You will end up with nine fingerprints, and the accuracy will not be affected in any way.

How do I turn Touch ID on, off, and customize my iPhone?

Before you activate Touch ID it is recommended to reboot your device, close all applications and wash your hands, as you will need to add fingerprints when you first turn it on, and if they are fuzzy, you may have problems unlocking your device in the future.

How to enable Touch ID or Face ID app locking

In the Automation tab, select Create Automation for Yourself.

Select a condition. App.

Check the Open option and specify the application in which you want to enable the lock.

Select action. Start timer for 1 second.

Make sure you disable the Ask before start switch.

Save the automation, and in the Clock app, set the Timer action when finished. Stop.

Now when you run the specified program, the automation will trigger, which sets the timer for one second. When the timer is triggered the iPhone screen will be locked. This prevents another person from using the app and will get a locked gadget if they try to launch it.

The smartphone owner simply authenticates using Face ID or Touch ID and continues to use the gadget.


What is Apple Touch ID

Touch ID is a fingerprint scanner and reader built into the device that identifies the user. It acts as an additional level of security (the security password is considered first) and is useful for quickly downloading or purchasing apps on your iPhone.

It’s an interesting and convenient technology that the American manufacturer has been using for over 7 years, making it easier for users to interact with the Apple device ecosystem.

How to use the technology

Apple’s Touch ID system lets you instantly perform an identity verification on your gadget with the touch of a finger, without entering a password.

Touch ID in the iPhone is used for 4 main tasks:

Unlocking your phone. Touch your finger with the Touch ID sensor to perform an action.

Purchasing items from iTunes and the App Store. To make purchases at these stores, you can use the Touch ID sensor instead of your Apple ID password.

Go to “Settings,” select “Touch ID and passcode,” and make sure the “iTunes Store and App Store” option is enabled on your phone. If it does not turn on, sign in with your Apple ID by selecting “iTunes Store and AppStore” from the “Settings” menu.

Click on what you want to buy

You’ll see a Touch ID prompt in the window that opens.

Tap the Touch ID sensor to make a purchase.

  • Payment transaction via Apple Pay. Touch ID can be used to make a variety of purchases through a payment service.
  • Allow auto-complete passwords

Touch ID system recognizes up to five fingerprints. So you can add a different finger from each hand. Or the addition of another person’s fingerprints is available. Let’s say you want to give a trusted friend or relative access to your phone using Touch ID. Please note that when registering multiple fingerprints, the recognition procedure slows down.

Apple first released Touch ID in late 2013 with the iPhone 5S and added the technology to the iPhone 8 and 8 Plus. In 2017, the U.S. corporation moved away from Touch ID with the introduction of the iPhone X, iPhone XS, iPhone XR and iPhone XS Max. These devices support Face ID, which identifies you by your face instead of your fingerprints.

How to set up Touch ID

To set up the sensor, enter the security code for your phone, and then follow the instructions:

Clean the home button from dirt and fingerprints.

In Settings, select the “Touch ID and passcode” section, then enter the password.

Click “Add fingerprint” and tap the desired finger on the sensor.

Hold your finger on the button until your phone vibrates or you’re prompted to do so.

Continue to hold and lift your finger in a measured manner, changing its position slightly.

The next screen will prompt the system to change the position of the phone in your hand. Hold it the way you’re used to holding it when you unlock and use it, touching the edges of your fingertip to the Touch ID sensor, not the center as you did in the beginning.

If the fingerprint does not register, we recommend scanning another finger.

Sensor Features

When the iPhone 5S first appeared on the smartphone market, similar biometric sensors were already being used on smartphones and computers from other manufacturers. The speed and accuracy of such sensors was of poor quality. The Cupertinians were the first to spread the use of technology, making it convenient and reliable.

Touch ID didn’t require the user to slowly slide a finger across a narrow strip of the scanner, recognizing a touch across the entire button area

Even with a dirty sensor, the sensor works correctly

The scanner recognized a touch from any angle, not just a certain orientation

This allowed the technology to become quite popular, and third-party gadget manufacturers began to copy the chip and port it to their smartphones and tablets.

Is it safe to use the scanner

The fingerprint and duplication technology itself is very complex and expensive to use. There were occasional hacks of Touch ID on the web, but they were isolated instances.

Thanks to Touch ID, mobile devices have a high degree of protection of user data. The fingerprints added to the memory of the mobile device are stored in a special encrypted Secure Enclave, which is located in the processor itself and is inaccessible to connections from the outside. It’s not easy to replace a broken sensor: it has to be replaced with the motherboard, where the processor is soldered in.

To summarize, Touch ID is a convenient and simple mobile technology that is designed to make it easier for iPhone owners.

How to download apps from the App Store without entering your password, Face ID, or Touch ID?

This question was sent by our reader. You can ask your question to Lifehacker, too. if it is interesting, we will surely answer it.

How to download applications from the App Store without entering a password or Touch ID on the iPad 2020?

I can guess why you have that question. I will try to answer it, but you probably won’t hear what you want to hear.

To start with a bit of backstory. Only free applications and games can be downloaded without entering a password. For paid applications, for obvious reasons, a password is always needed. The corresponding option was present on the iPhone and iPad for quite some time, but over time has lost its relevance, and in iOS 14 Apple has finally removed it.

The thing is, downloading free apps only works when Face ID / Touch ID is turned off, which is a very illogical scenario. Enter the password manually for each paid application to be able to install free ones without a password? Not very convenient.

With the advent of Touch ID and Face ID, the smartphone or tablet began to ask for confirmation of the installation of any application, including free. It is understandable, because it is not difficult to look at the screen or put your finger to the button, and this action does not take much time.

Now, the answer to the question. The 8th generation iPad (2020) has iOS 14, so you can’t download apps from the App Store without entering your password. On iPads or iPhones with earlier versions of iOS this is possible. To do this, you need to do the following:

  • Open “Settings” → “Face ID / Touch ID and password code” and turn off the “iTunes Store and App Store” toggle switch.
  • Go to “Settings” and tap your profile picture.
  • Go to “iTunes Store and App Store” → “Password Settings” and in the “Free Downloads” area, turn off the “Password Request” toggle switch.

What to do if Touch ID does not work in the App Store?

Go to Settings on your iPhone or iPad and go to Touch ID and password. If the code request function is enabled, it can be requested.

Turn off the iTunes App Store.

Next, the device must be rebooted. Hold down the lock/sleep button. Repeat the same steps to turn the device back on.

Then you need to go back to Touch ID and password in Settings.

Turn on iTunes App Store.

After doing this, any attempt to make a purchase from the App Store will require the user to use Touch ID, not the Apple ID password. Keep in mind that if you have not made a purchase from the App Store for a day, the device will still require you to enter your Apple ID password.

It happens that this problem occurs due to incorrect operation of the Touch ID hardware. This is why you need to make sure it is functioning properly. This can be checked by using Touch ID on the locked display to unlock the device.
