Face ID on iPhone X is one of the leading security technologies dominating the market nowadays, sparking a trend of facial recognition technology adoption in numerous affordable and mid-range smartphones from China.
So, is Face ID secure? What are the pros and cons of facial recognition technology using Face ID?

1. Outstanding advantages of phone unlocking technology with Face ID
Accurate recognition: Since its debut on iPhone X, FaceID has demonstrated optimization with an error rate of only 1 in 1 million compared to Apple's fingerprint security at 1 in 50 thousand, which is 20 times lower. Each person has a unique face, even identical twins.
High security: Developed to completely replace TouchID on iPhone, FaceID is meticulously researched for the highest level of security, making it very difficult to bypass with its 3D facial recognition. Your facial feature data will be stored on the device itself rather than on any server or elsewhere to ensure security.
Swift and intelligent: Alongside ensuring facial accuracy, the recognition speed is also highly praised for being rapid and intelligent.
Apple has integrated AI (artificial intelligence) into FaceID to unlock the device only when the user is looking at the screen and continuously learns to adapt to facial changes over time (such as weight loss, weight gain, growing facial hair...) or accurately recognizes even when wearing makeup, glasses, or a hat.
You also don't need to place your eyes in a specific position like eye-based security; just looking at the phone screen is sufficient.
2. Disadvantages of Face ID technology on iPhone X
Despite a range of advantages, Face ID also encounters some drawbacks:
- Security level still lags behind iris or retina scanners used on some smartphones today.
- Unlocking speed is relatively slow, trailing behind fingerprint scanners.
- Unable to unlock in certain specific cases.
However, overall, Face ID is still highly rated for its security capabilities and unlocking on smartphones. Users can completely trust its usage.
