For those people who are paranoid about their personal messages getting seen by someone they don’t want to, here’s some good news for you guys. WhatsApp has come back with its fingerprint lock feature for Android beta users, after making it available to iOS users for a while now. It comes with the latest Android beta version 2.19.221 and is disabled by default. Users will need to enable it in Settings, and this feature will allow users to add a layer of protection to their app chats, making sure no unwanted people manage to read your personal chats. A new feature, ‘show content in notifications’ option added allowing users to decide if they want to show or hide message and sender preview when the fingerprint lock is enabled.
As mentioned, the fingerprint lock option is enabled in the Android beta version 2.19.221 – currently the latest version. It is disabled by default. The method to unlock it is by going to WhatsApp Settings > Account > Privacy > Fingerprint lock. If your phone has already been updated to the latest version of Android and you still haven’t managed to get the feature, back up your WhatsApp and reinstall it. Notably, the feature requires the phone to be running Android Marshmallow or higher, and feature a fingerprint scanner.
When enabled, users will need to use fingerprint authentication to unlock WhatsApp and gain access. There are three options for ‘automatically lock’ to choose from – immediately, after 1 minute, and after 30 minutes. Users can choose from these options according to their preferences. Choosing the’ immediately’ option will require the user to fingerprint authenticate every time they close and open the app.
