WhatsApp Fingerprint Lock or Authentication or Screen Lock appears to be finally rolling out, first to the beta users, of course. The popular WhatsApp Beta tracker has revealed this and mentioned that the version 2.19.221 Android Beta will bring this change to the testers for now.
Currently, it’s unknown when this new feature will roll out to everyone, but it’s good to note that it’s finally arriving. The feature was reported many times before, thanks to the traces found in the previous versions. It was spotted as a disabled feature before but it at least gave a strong hint that this could land anytime soon.
WABetInfo advises that if you have already updated to this version but unable to see this feature then first back up your chat history and reinstall WhatsApp.
And, to enable the Fingerprint Lock, you need to open WhatsApp Settings> Account > Privacy and find an option to enable Fingerprint Lock.
Unlike previously, the new feature looks improved and better serves your requirements. It lets you choose the period you want the authentication to get enabled. You can choose an ‘Immediate’ lock, After 1 minute or After 30 minutes options to set your requirements. So, if you choose “Immediate Lock,” WhatsApp will ask for authentication every time you open the app. This option is best suited for users who are quite concerned about privacy and don’t want to leave their app open for even 15 minutes.
Furthermore, you can also choose to show content in notifications. If the toggle switch is enabled you will be able to preview sender and the message text inside new message notifications.
Users will still be able to reply through notifications even if the Fingerprint Lock feature is enabled since the authentication is only required when you open the app.
Note that several apps and even phones offer App-wise authentication where we get to choose which apps should be locked. But this new feature is baked right inside the app which means it’s more secure. The outer App Lock feature by several phones tend to fail sometimes, but the new Fingerprint Lock system by WhatsApp will work every time, depending upon the time period you have chosen. So, if you have already set an App Lock on your app, enabling the WhatsApp feature will bring double verification, which may not be needed. But having an in-built feature of an app is always useful.
