Roughly six months back, iOS beta users have been enjoying the fingerprint locking feature on their WhatsApp app, making it possible to use Touch ID to unlock the app but this time around, it has been rolled out to Android users.
The authentication feature is similar to those using iPhones or iOS phones. You will be able to open WhatsApp app using fingerprint sensor and more also, users will still be able to reply to messages and answer calls from the notification shades, even when the app is locked.
You can also set the time the feature should automatically lock your WhatsApp app after 1 minute or 30 minutes. However, if you disable the “show contents on notifications”, WhatsApp will no longer show the sender and message preview when you enable the fingerprint lock feature.
To enable the feature, head over to Settings>> Account>> Privacy and tap on the Fingerprint Lock option. Once you enable the feature, you will always have to tap on the fingerprint sensor to unlock your WhatsApp app.
This feature is currently available to Android users on latest 2.19.221 Beta program of WhatsApp. Beta users are those who test an app features before the official rollout. Meanwhile, since the fingerprint locking feature is already available on the Beta stage of WhatsApp, the official rollout won’t take time where everybody who are using WhatsApp will enjoy the feature.
