How to Turn On Face ID, Touch ID Biometric Authentication on iOS – WhatsApp

Whatsapp’s biometric authentication feature was first anticipated in October last year. However, it does not give you any additional security to one-to-one chat. It is to be noted that this feature is yet to be launched for Android users.

Whatsapp’s biometric feature will work similar the way Outlook and Signal are offering Face ID and Touch ID for many months. If you want to experience this change in your handset, you will have to download the latest version of the app from the App Store. It only weighs 137.7MB and is compatible with iPhone models running iOS 8.0 and above.
