FingerPrint Lock on WhatsApp

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 2.19.20.19 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 on WhatsApp application for the iPhone. It has been introduced to make conversations safer, in addition to the already existing ‘end-to-end encryption’ meaning only the chatting users can access their messages.

For users with iPhone X or above, FaceID unlock is available. And, for users with iPhone below that, the Facebook-owned company has introduced TouchID or passcode. The Authentication feature is available in WhatsApp Settings > Account > Privacy.

To start the Fingerprint lock on WhatsApp as a 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. To use the feature, users will have to close the app and restart it. The app will then ask to authenticate their identity in order to use WhatsApp. If any of the authentication process fails, users can use the passcode to access the app.

Since the fingerprint and face unlock data are encrypted on the iPhone, WhatsApp will not get users’ security data as it is managed on phone-level access and extraction of this information is not possible. The feature will be immediately enabled in the next 2.19.20 App Store update.

Apart from this, WhatsApp now also allows the users to download a specific sticker from a stickers pack. This means that users don’t need to download the full stickers pack. For this, they simply need to open the WhatsApp Stickers in-app Store, then select the stickers pack and tap and hold the sticker they want to add.
