Biometric identification has been added to facebook Messenger. This will make the correspondence secure.

Facebook introduced biometric identification in the Messenger app. The function is already available on iPhone and iPad starting today and will appear on Android in the next few months.

Facebook has confirmed that they started testing Messenger blocking in early 2020. The social network is confident that this feature will allow users to transfer phones or tablets to friends or family without worrying about the safety of their correspondence. A year ago, Facebook also introduced biometric unlocking for WhatsApp.

App Lock will be compatible with any privacy settings offered by the device itself. For example, iPhone 5S – iPhone 8 can enable fingerprint lock, while iPhone X and later can enable Face ID. App Lock will also be compatible with the standard password – users will be able to protect Messenger with a PIN.


To activate the new function, you need to go to the “privacy” section, and then turn on the App Lock function by selecting the desired option. You can activate App Lock after exiting Messenger, after one minute, 15 minutes, or an hour.

Facebook is also working on several new privacy-focused Messenger features. One of them allows you to control who can send messages or call users. Another feature will automatically blur images that are sent from unknown accounts.

In 2021, the social network will implement end-to-end encryption of messages inside Messenger. For now, users have to create special secret chats for this.
