The Facebook messaging app has been smoothly updated to version 2.19.20 over the weekend and, as noted in the update; WhatsApp now includes support for Apple’s Face ID and Touch ID.
To activate the new feature, you must go to the settings inside the app, then hit “account, “>” privacy “and “screen lock”.
There, you can choose to activate Face ID or Touch ID, although the option available depends on your iPhone model— Touch ID is available on iPhone 5S via iPhone 8/8 Plus. Face ID replaced the iPhone X Touch ID.
WhatsApp is now Facebook’s most popular mobile app, according to recent App Annie data, and with data privacy seldom in the headlines; it is clear that Facebook wants to place itself as a privacy and security oriented company, despite recent controversies.
Allowing users to lock WhatsApp behind a biometric authentication system could certainly help this broader mission, and the company seems to be preparing something similar for its Android app, as shown by a recent beta build.
