A secret trick Face ID you may not know

Face ID is renowned as Apple‘s cutting-edge facial recognition system, offering unparalleled security for mobile devices. In the latest release of iOS 16.4, Apple has introduced an exciting new feature within the Shortcuts app, designed to enhance user privacy. Curious to learn about this new Face ID function? Let’s explore it in detail below:

Face ID, the revolution of evolution

Since its introduction in 2017, Face ID on the iPhone has continually evolved, undergoing advancements in size reduction, technological enhancements, and expansion to other Apple devices such as the iPad Pro. Its unrivaled recognition capability offers a unique and superior level of protection for your iPhone, surpassing competitors in the market.


Initially, Apple allowed app developers, including popular ones like WhatsApp and banking apps like N26, to integrate Face ID for enhanced control and security within their respective applications. However, over time, it appears that Apple has undergone a strategic shift, now focusing on bolstering security within its own native apps as well.

Block apps with Face ID


In the latest iOS 16.4 update, a new feature allows you to restrict access to specific applications on your iPhone. This is particularly useful in situations where you want to prevent unauthorized access to certain functions or sensitive apps like the Gallery. The process is straightforward and can be completed in six simple steps:

1. Open the Shortcuts app on your iPhone and navigate to the Automation tab.
2. Tap on the “+” icon in the top right corner to create a new personal automation.
3. Select the desired app that you want to “lock” and choose whether you want to use Face ID or Touch ID for authentication. Note that iOS 16 is compatible with devices like the iPhone 8 and iPhone SE.
4. Tap “OK” and then proceed to the next step.
5. Add the desired action to be performed.
6. Finally, tap “Next” and disable the option to request confirmation. Press “OK” to complete the process.

Following these steps, you will have successfully implemented the app lock feature on your iPhone.


Other Face ID features

To adjust the speed of Face ID unlocking and the auto-lock duration on your iPhone, follow these steps:

1. Open the “Settings” app on your iPhone.
2. Tap on “Display & Brightness” from the list of options.
3. Select “Auto-Lock.”
4. Choose the desired duration for the auto-lock feature to activate, such as 30 seconds, 1 minute, or any other available option.

It’s important to note that increasing the speed of Face ID unlocking can potentially impact the security of your device. It is recommended to keep the facial recognition time within the timeframe established by Apple to maintain optimal security.
