WhatsApp now allows iPhone users to unlock the app with their face or fingerprint.
The Facebook-owned messaging app was quietly updated over the weekend to version 2.19.20 and, as the update notes state, WhatsApp now includes support for Apple’s Face ID and Touch ID.
To activate the new feature, you’ll need to head to the settings inside the app, then hit “account,” “privacy,” and “screen lock.” There, you can choose to activate Face ID or Touch ID, though of course the available option will depend on your model of iPhone — Touch ID exists on the iPhone 5S through to the iPhone 8 / 8 Plus. Face ID replaced Touch ID from the iPhone X onward.
Once the feature is activated, you can stipulate if you need Face ID or Touch ID immediately or after 1 minute, 15 minutes, or 60 minutes of inactivity.
One of WhatsApp’s big selling points is its end-to-end encryption, meaning no prying eyes — including those at WhatsApp itself — can read your messages. This has led to much criticism from governments around the world, as they are unable to intercept communications from criminals or those under suspicion.
Rather than caving, however, Facebook appears to be doubling down on its encryption efforts — last week, news emerged that the company plans to unite its trio of messaging apps (Messenger, Instagram, and WhatsApp) under a single infrastructure that will include end-to-end encryption by default across all three.
Allowing users to lock down WhatsApp behind a biometric authentication system goes some way toward helping that broader mission, and it seems the company is preparing something similar for its Android app, as evidenced by a beta build that recently emerged.
