Instant messaging platform WhatsApp has implemented the most-awaited authentication feature for all its iOS beta users.
The feature was spotted by WABetainfo and has been added with the new 22.214.171.124 beta update published through TestFlight beta program.
It is part of features being introduced by WhatsApp through its first official beta program.
The new update now adds fingerprint lock to the WhatsApp application on the iPhone.
It has been introduced to make conversations safer, in addition to the already existing ‘end-to-end encryption’.
The Authentication feature is available in WhatsApp Settings > Account > Privacy.
To start the authentication feature for their devices, users need to choose screen lock from settings.
Despite this, the users will continue to reply to messages straight from the locked screen notifications.
They will also be able to reply to calls without any authentication. The user will have to configure the TouchID or FaceID unlock feature on WhatsApp.
The feature will be immediately enabled in the next 2.19.20 App Store update.
