Apple's Touch ID is a fingerprint-scanning security system that was introduced with the iPhone 5s in 2013. It allows users to unlock their devices and make purchases using Apple Pay. Touch ID can also be used to switch between user accounts on a shared device. However, a significant drawback of Touch ID is that it can be bypassed even when the user is asleep, as long as the perpetrator has access to the registered fingerprint. This has raised concerns about the security and privacy of users, especially in situations where an unauthorized person gains physical access to the device. As a result, some users prefer to enable a passcode lock or use alternative security measures such as Face ID, which offers a higher level of security but may be less convenient in certain situations.

What You'll Learn
Touch ID works when sleeping
Touch ID has been replaced by Face ID on iPhones. While Touch ID works when the device is sleeping on MacBooks, it has been reported to malfunction on some MacBook models.
On the Mac, after periods of inactivity, the display turns off and the computer automatically goes into sleep mode. When the Mac wakes from sleep, Touch ID may fail the first time and ask for a password. However, if you then hit ESC to re-lock the screen and wake it again, Touch ID works, and usually continues to work fine for the rest of the day. This issue seems to occur after a prolonged sleep, such as overnight.
On the iPhone, Face ID cannot unlock the phone while the user is sleeping. This is because the TrueDepth camera looks for the user's eyes and sees if they are open or not. There is also an additional layer of security with the "require attention to unlock" setting. If someone tried to unlock your phone while you were sleeping, they would have to keep your eyelids open, which would likely wake you up.
If you want to check something on your iPhone while you are sleepy, you can set related widgets on the lock screen or ask Siri to check things for you. Alternatively, you can unlock your iPhone with a voice command, which you can set to mimic how you enter the correct passcode.

Touch ID fingerprint security issues
Apple's Touch ID system is a mobile identification system that allows users to unlock their devices and make purchases by scanning their fingerprints. While this technology offers convenience, some security concerns have been raised about potential flaws in the system.
One of the main security issues with Touch ID is that it cannot detect whether the user is conscious or not. This means that someone could unlock a user's device by placing their registered finger on the sensor while they are asleep. This has raised concerns about the potential for misuse by partners or friends who may be tempted to snoop through another person's phone without their knowledge or consent.
Another security concern with Touch ID is the possibility of replicating a person's fingerprint. Analysts have found that it is possible to create a replica of a person's fingerprint using various methods, including photographs and Play-Doh. This means that a malicious actor could potentially gain access to a user's device by creating a fake fingerprint.
Additionally, there are challenges in limiting access among multiple authorised users of a device. In a workplace setting, for example, it may be difficult to track purchases made through a shared Touch ID-enabled device. While multiple fingerprints can be saved, this also increases the potential security risks if unauthorised users gain access to the device.
While Touch ID offers a convenient way to secure devices, it is important for users to be aware of these potential security issues and take steps to protect their information. This may include enabling additional security measures, such as a passcode, or being cautious about the number of fingerprints enrolled on their device.

Face ID vs Touch ID
Apple introduced Touch ID in 2013 with the iPhone 5s. Touch ID takes a high-resolution image of small sections of the fingerprint from the subepidermal layers of the skin and then uses intelligent analysis to identify a match. Touch ID can be used to unlock your iPhone, Mac, and iPad, as well as to make purchases using Apple Pay. However, one drawback of Touch ID is that it can be used to unlock your phone even when you are asleep, as long as the person trying to unlock it knows which fingerprint is registered.
In 2017, Apple introduced Face ID with the iPhone X, which uses facial recognition to authenticate the user. Face ID uses a TrueDepth front-facing camera to project more than 30,000 invisible dots onto your face to map its structure, which is then transformed into a mathematical model and compared to the facial scan stored during the setup process. Face ID also captures an infrared image of your face, which is combined with the depth map by the neural engine of the iPhone's or iPad's chip. Face ID is more secure than Touch ID, with Apple claiming that there is a 1 in 1,000,000 chance that a random person could unlock your device, compared to 1 in 50,000 for Touch ID. Face ID also includes an attention awareness feature, which can be turned off, that requires your eyes to be open and looking at the iPhone for it to unlock. This means that Face ID will not work if you are asleep.
Some users have expressed a preference for Touch ID over Face ID, citing convenience and faster unlocking speeds. For example, Touch ID can be used to unlock your iPhone while it is still in your pocket, whereas Face ID requires you to look at the screen. Additionally, Touch ID can be used to unlock your device without having to press any buttons, whereas Face ID requires a swipe up from the bottom of the Lock Screen. On the other hand, Face ID is considered more secure due to the lower probability of a random person being able to unlock your device. Face ID also offers a unique shortcut for switching between apps, swiping right or left on the bar at the bottom of the screen, whereas Touch ID requires pressing the Home button twice and then swiping between apps in the App Switcher.

Touch ID on Mac
Touch ID is a convenient feature on Mac that allows users to unlock their device, make purchases, log into third-party apps, and authenticate Apple Pay using their fingerprint. While Touch ID can be used to unlock a Mac when it wakes from sleep, there are some instances where it may not work as expected.
One common issue reported by users is that Touch ID fails on the first attempt after waking their Mac from sleep, especially after prolonged periods of inactivity or overnight sleep. In such cases, the user is prompted to enter their password, and Touch ID works fine for the rest of the day after a manual re-lock and re-wake. This issue has been observed on various Mac models, including MacBook Pro, MacBook Air, iMac, and Mac Mini.
To address this issue, several solutions have been suggested. One quick fix is to keep the keyboard charged or re-pair it with the Mac. Other solutions include ensuring that the finger and Touch ID sensor are clean and dry, as moisture, lotions, sweat, and dry skin can interfere with fingerprint recognition. Users can also try deleting and adding their fingerprint again or using a different fingerprint.
For more advanced troubleshooting, users can try resetting the System Management Controller (SMC) on their Mac. The SMC manages important hardware settings, including Touch ID, and resetting it can restore its functionality. The process for resetting the SMC varies depending on the Mac model and the presence of a T2 chip. For example, on MacBook, MacBook Pro, and MacBook Air with T2 chips, users need to turn off their Mac, hold down the Touch ID button for 10 seconds, release it, and then turn on the Mac. On the other hand, for MacBook, MacBook Pro, and MacBook Air without T2 chips, users need to press and hold the left Shift + Control + Option + Touch ID buttons simultaneously for 10 seconds before releasing and turning on the Mac.
Additionally, it is recommended to ensure that the Mac is running the latest macOS updates and that all relevant features are turned on in the Touch ID settings. If the issue persists, users can refer to Apple Support for further assistance.

Touch ID troubleshooting
Touch ID is a security system that can be easily unlocked by a registered fingerprint. However, it cannot detect whether the person is asleep or unconscious. This means that someone could unlock your phone with your fingerprint while you are sleeping.
If you are experiencing issues with Touch ID, there are several troubleshooting steps you can take. Firstly, ensure that your finger and the Touch ID sensor are clean and dry. Moisture, lotions, sweat, oils, cuts, or dry skin can interfere with fingerprint recognition. Use a lint-free cloth to wipe off any dirt or debris from the sensor.
Next, check that your finger is covering the Touch ID sensor completely and touching the surrounding metal ring. Avoid tapping too quickly or moving your finger around while scanning. If you're using a case or screen protector, ensure it doesn't cover the sensor or the surrounding ring.
If the issue persists, try restarting your device. Go to "Settings" > "Touch ID & Passcode" and disable all options. Then, restart your iPhone or iPad and re-enable the desired features.
For Mac users, if Touch ID isn't working as expected, such as for unlocking your device or autofilling passwords, try turning the keyboard off and back on. Then, use a USB cable to connect it directly to your Mac. If the problem occurs wirelessly, check for wireless interference. Additionally, ensure that your Mac is up to date with the latest macOS updates.
If Touch ID still isn't working, you may need to delete your fingerprint and add it again in the Touch ID settings or try enrolling a different finger.
