According to press reports on Monday, WhatsApp is developing a new feature that allows users to lock and unlock via a fingerprint in an effort to provide additional protection for their accounts.
The WABetaInfo technical website said WhatsApp was testing the new feature in the beta, and it could take several months before the feature was officially announced in the new application update.
After the long Christmas holiday, the Instant Messaging app sent a new update to its application to the Google Play Store trial program, as part of the steps to test the new feature.
The new update includes the “authentication” feature, which will initially be available on Android-powered smartphones and later added to IOS phones.
The technical site posted an image that appears from the application in the trial version, closed the application interface and blocked its messages, and at the bottom a button with “Approve” approval to open the application.
With the fingerprint, you can lock chats and contacts saved in the app, as well as lock the application permanently.
In a move to make it easier for users, WhatsApp added the advantage of using a personal identification number that could be used if there were fractures in the fingerprint scanner.
