Gone were the times when people were oblivious about their online security and privacy. Now most of us take the security of our data seriously. And the good thing is most messaging apps today come with a set of security features including biometric lock to shield our personal information. In this quick guide, I’m going to show how you can lock WhatsApp, Telegram, and Signal with Face ID on iPhone for an additional layer of safeguard.

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.
