Key takeaways. All three authentication methods are secure enough for average users. However, the possibility of a lookalike relative getting past your iPhone's Face ID may concern those with rocky familial relationships. And it's probably best for almost everyone to avoid using a four-digit passcode.
Encrypted and Secure
According to Apple, the odds of a random person looking at your iPhone or iPad with Face ID and unlocking it are slim: 1 in 1,000,000. Additionally, Face ID uses a three-dimensional depth map of your face, so 2D prints of photographs of your face won't work.
Face ID and Touch ID don't replace the user's passcode or password; instead, they provide easy access to the device within thoughtful boundaries and time constraints.
Face ID is safe 100% because the probability that another person can unlock your iPhone with Face ID is less than one in 1,000,000. If you're concerned about individuals accessing your iPhone, you can set the Face ID security to security Face ID with a mask.
With a little luck, a hacker can crack your mobile device's password. However, it's nearly impossible to replicate you. Or more specifically, your fingerprints and your face. In fact, there's a one in 50,000 chance of your fingerprint scan being hacked and a one in a million chance of your Face ID getting hacked.
You need to reset Face ID and then activate it again with your face. Then if someone else wishes to use your device, you need to unlock it and hand it to them, and not let them look at the phone and unlock it with the passcode. That is how Face ID learns changes to your face as well.
If the Apple Watch is connected to the phone and is unlocked, the phone will unlock even without using Face ID. Android devices don't have the same ability.
As for security, both Face ID and Touch ID data are stored in a Secure Enclave as mathematical data only the OS can access. However, Touch ID seems to be the one more likely to protect your device from an intruder.
Unlike other Android devices which just use the front camera or IR sensor, the Find X brings a number of sensors including a flood illuminator, an infrared camera, a ranging sensor, and a dot projector, just like on the iPhone X. In the Android world, Oppo Find X has the most secure face unlocking mechanism.
Touch ID is currently more reliable than Face ID for some of the reasons which have been touched upon: Fingerprints are less subject to change than facial appearance. Fingerprint recognition doesn't depend on a specific camera angle. Fingerprint patterns are more unique than facial patterns.
Forbes just posted a leaked render of the iPhone 12, and it still has a notch. The notch is there because of the technology that helps Apple recognize your face. If facial recognition wasn't included, they could just cut out enough room for the camera.
Face ID data — including mathematical representations of your face — is encrypted and protected with a key available only to the Secure Enclave. This data will be refined and updated as you use Face ID to improve your experience, including when you successfully authenticate.
It's relatively safe to store passwords on iPhone Notes only if you keep the note locked behind a password. However, there are better password storage options offering more security and organization than iPhone notes, especially when it comes to storing sensitive information.
Face ID data—including mathematical representations of your face—is encrypted and protected by the Secure Enclave.
For nearly all people, it is much safer to use fingerprint or face scans to secure your devices and accounts than using just a password. “It is so much better than the alternative,” said Chester Wisniewski, an internet security researcher with the firm Sophos.
Or perhaps you're wondering what you do instead if you choose not to setup Face ID. If you don't like the idea of Face ID or having your iPhone scanning your face for whatever reason, then you'll be relieved to know the answer is yes, you an absolutely use the iPhone X without ever using Face ID, it is not required.

It's the kind of feature worth buying a new iPhone to get—it only works with the iPhone 12 and iPhone 13.
Many phones that can be unlocked using facial recognition can be fooled by a photograph, research has found. According to consumer body Which?, scammers can bypass the screen lock on certain Android phones and access sensitive information.

Though deepfakes can be deceptive to the naked eye, they're not advanced enough to fool facial-recognition software. Deepfake videos and images are two-dimensional, which is why they can't be used to unlock a smartphone, like an Android or Apple device.
For users who have not changed their accessibility settings, Apple's Face ID face recognition system does not work if the user has their eyes closed.
personal security and privacy. It's worth pointing out that police, government agents, or customs officials could force you to unlock your device using Face ID or Touch ID.

Apple Face ID failure may occur if there is an electricity leakage or short-circuit issue after water damage or exposure to a humid environment. The circuit or Face ID software can become compromised due to moisture buildup after water damage.
