New Delhi | Jagran Tech Desk: WhatsApp has started a fingerprint lock feature for its Android beta users after initially availing it to the iOS users. The feature is available for Android beta version 2.19.221 which is disabled by default. Users will need to enable it in the settings. This feature will allow users to add an extra layer of protection to their chats. There is also an option to keep or hide the chat content preview when the fingerprint lock feature is enabled.

In order to enable the feature go to WhatsApp settings > Account> Privacy>Fingerprint lock. If you have updated your device and do not see the feature, then all you need to do is back up your chat history and reinstall the app. Notably, the features will run on Android Marshmallow or higher version which must include fingerprint scanner.

In Android beta version 2.19.221 there is a new option in settings called Show content in Notifications. Users can decide if they want to see the WhatsApp chat content preview or not when fingerprint lock feature is enabled.

If you do not enable the option, anyone can reply to your WhatsApp messages or answer WhatsApp calls. Its features tracker WABetaInfo says that when you enable the Fingerprint Lock feature, the widget content is hidden by default.
