WhatsApp Beta on Android is now finally deploying a fingerprint conversation protection feature. iOS users have been enjoying it for several months. Fingerprint protection for conversations is available now in the latest beta of WhatsApp on Android (version 2.19.221). It is activated from the privacy settings and to take advantage of it, it is of course necessary that your phone must have a fingerprint sensor and a valid fingerprint is configured in the security settings of Android.
Once fingerprint authentication is enabled, the setup screen will delay WhatsApp lock by several minutes so you do not have to enter your fingerprint every time you open the app. Three options are available: immediate lock, after a minute or thirty minutes . The last option seems to us the most appropriate. Whenever you quit WhatsApp or the screen turns off, you will not need to unlock the app when you return within 30 minutes. It is more convenient when for example in full conversation.
Fingerprint Unlock on WhatsApp Beta
The feature can be activated by going to WhatsApp Settings> Account> Privacy> Fingerprint Lock . To access it, download the latest beta version of WhatsApp via APK — direct link available ahead. Fortunately, you can run the beta installation side by side your normal WhatsApp as it does not overwrite the standard application already installed. The second step is to register for the beta program through this link (registrations are open intermittently).
Finally, another option on the configuration screen is to hide or not the contents of the messages in the notification cards. We have tested all this and it works very well. But it could be that the new feature does not appear in everyone even after installing the beta and joining the program. 9to5Google recommends trying to clear the application cache and restart it. But be careful, this may require a restoration of conversations as long as you save them regularly. If you do not want to take the risk, the feature should arrive in the public version of WhatsApp in the coming weeks.
Once done activating the fingerprint lock, close the WhatsApp then launch it again. This time it will ask for your fingerprint to open the WhatsApp conversations. If you are the beta tester, then tell us how it is working out for you in the comment sections below.
