Lock WhatsApp, Telegram, and Signal with Face ID on iPhone
Introduced in 2017 with iPhone X, Face ID is widely considered to be the gold standard of facial unlock on any smartphone. What it loses on the speed front, it gains on the security aspect. Notably, Face ID also adapts to changes in your appearance so that unlocking the device or app should not be a hassle even when you have grown facial hair or put on a cosmetic makeup. However, bear in mind that if it notices significant change in your appearance, you will be forced to confirm your identity by using your passcode. Even when you have locked WhatsApp, Telegram or Signal with Face ID, you can continue to answer calls and even reply to messages from notifications. It’s worth pointing out that if your device supports Touch ID, you will get the option to lock these messaging apps using Touch ID.
Lock/Unlock WhatsApp Using Face ID on iPhone
Launch WhatsApp on your iPhone.
Now, tap on the Settings icon at the bottom right corner of the screen.
Next, tap on Account.
Next up, tap on Privacy.
Up next, tap on Screen Lock.
Now, turn on the switch right next to Require Face ID. After that, you can choose to lock WhatsApp immediately after you close the app, after 1 minute or 15 minutes or 1 hour.
For better security, I would recommend you to go with the “Immediately” option. Going forward, you will be able to unlock the messaging app using Face ID. Do note that you will still be able to reply to messages from notifications and answer calls even if the app is locked.
Lock/Unlock Telegram with Face ID on iPhone

Set Up and Use Face ID with WhatsApp, Telegram, and Signal
So, that’s how you can lock these popular messaging apps using Face ID on your iOS device. As it’s always better have an extra layer of safeguard to stop unauthorized access, get the most out of the facial unlock technology to secure your personal information. That said, which one of these messaging apps is your favorite? WhatsApp may claim to be the most popular messaging app, it lags behind Signal and Telegram on the privacy front.
Moreover, the controversial privacy policy that was recently announced has put the Facebook-owned messaging app in a spot of huge bother. It would be great to have your feedback and the reasons that forced you to switch to Signal or move to Telegram from WhatsApp, if you did decide to take that step.
