Face ID is one of the most convenient authentication methods used in Apple devices, but is it safe? Let’s compare it with other popular security measures and find out. What is Face ID? } description={ } /> Apple popularized Face ID technology, which appeared on the iPhone X in 2017. Since then, many other devices have adopted similar biometric authentication methods. The name “Face ID” is reserved for Apple devices, but other companies, such as Google and Samsung, also use facial recognition in their products. Is Face ID safe? Yes, Face ID is safe. The technology uses Secure Enclave, a special subsystem built into Apple’s systems on chips (SoC) that is separate from the main processor. This system is designed to secure sensitive information, such as biometric data. The Secure Enclave subsystem works with Apple’s TrueDepth camera system, which captures your distinct facial features and displays thousands of invisible dots on your face, creating a depth map and generating an infrared image. Machine learning technology then analyzes these images and creates a mathematical representation of your face. All this data is encrypted and secured by the Secure Enclave subsystem, which stores a decryption key. Face ID data never leaves the device. This information is crucial because safety-concerned users may be uneasy about privacy when a company has access to and stores their sensitive biometric data.You may be legitimately concerned that information about your facial features may be stored in the iCloud or elsewhere, but the mathematical model of your face is not backed up anywhere outside your device. Is Face ID enough? In rare situations, Face ID may not be enough to secure your iPhone properly. One of these situations involves siblings and close family members. If you have a twin, Face ID may have difficulty distinguishing between the two of you, and they may unlock your device by looking at it. The same may apply to other relatives who look very similar to you or children under 13 because their facial features may not be fully developed. In some cases, Face ID can also be used to unlock your device without your consent. Thieves and authorities may threaten or trick you into looking at your phone to access it. If you haven’t enabled Attention Aware features, you don’t even have to look at the device to unlock it, allowing someone to point your phone at your face and unlock it while you’re asleep or unconscious. For the most part, Face ID is still one of the most secure authentication methods used on Apple devices. Unless you’re a politician, a whistleblower, a spy, or some other kind of targeted activist, and you don’t have powerful enemies hunting you, it’s highly unlikely that someone would go out of their way to bypass Face ID on your phone. Face ID is perfectly safe for most users and can protect your mobile devices from unauthorized access. It’s also a safe way to protect stored passkeys used for logging in to various accounts. Is Apple Face ID safer than Touch ID? Touch ID is another popular authentication method in which the device uses your fingerprint to verify your identity. Which one is more secure? Let’s compare the two methods. Generally speaking, Touch ID may be slightly more secure than Face ID, especially if you are worried about doppelgängers (such as twins and other similar-looking family members) unlocking your mobile devices. Touch ID would be more reliable in such a situation because even identical twins have unique fingerprints. But if you’re not worried about your twin accessing your phone, Face ID is a safe option for you. {SHORTCODES.blogRelatedArticles} Face ID vs. passcodes Passcodes are still the most popular way to protect mobile devices against unauthorized use and were used long before Face ID and Touch ID. Do they pass the security test? Let’s find out.
When it comes to passcodes, their safety depends on length and complexity. For example, a 4- or 6-digit numeric code can be easy for “shoulder surfers” to repeat. Moreover, many people use easily checkable information as their passcodes, such as their or their children’s/spouse’s dates of birth. Longer and more complex codes are usually more reliable. They’re harder to remember for shoulder surfers, and you can’t provide them while unconscious. So which method is better, Face ID or passcodes? It all comes down to personal preference. Biometric authentication is usually safer in public places where someone can sneakily see your password, but Face ID can be used against you in certain situations. However, both methods are safe in most everyday situations, especially if you use long and complex passcodes.

No. While some reports indicated that Face ID worked with photos in the past, the technology has since been improved. Face ID calculates depth and compares it with stored data. Depth information cannot be calculated from a 2D photo. ), }, { question: ‘Is Face ID safe for banking?’, answer: ( Yes, Face ID is safe enough that many banks and financial institutions trust it. Apple has strong security and privacy measures to ensure that Face ID technology provides the best possible biometric authentication. ), }, { question: ‘Is Face ID safe for health?’, answer: ( Yes. Face ID technology uses a laser system to project little dots onto your face, but the output is so low that it won’t cause any damage to your skin or eyes. The system uses infrared wavelengths, which are also present in the light emitted by screens, or even sunlight, but much less intense in this case. In other words, going outside on a sunny day or watching TV causes more infrared exposure than using Face ID. ), }, ]} />
