In order to provide one more layer of user protection, WhatsApp is finalizing the details to enable fingerprint lock and just released a new update for users of the beta on Android.
The protection of WhatsApp messages was already more than covered thanks to the end-to-end encryption that all chats have. But nothing prevented someone with physical access to the unlocked smartphone from entering and taking a look at the conversations.
If you are a user of WhatsApp beta you need to update the application to the version 2.19.221. If you already have it but the fingerprint lock function does not appear and you cannot wait any longer, you will have to make a backup of the conversations and reinstall the application.
The minimum requirements to access this function are quite basic. The smartphone (or tablet) must have installed at least Android 6 Marshmallow and, of course, have a fingerprint reader.
According to the published screenshots we will find the fingerprint lock in the Privacy section within the WhatsApp configuration. There we will have a button with which to activate it and it will let us configure the automatic blocking time and if we allow the messages to be read with WhatsApp blocked.
When we want to access with the locked app, a screen will appear indicating that we have to place our fingerprint on the reader in order to open it.
It’s interesting to know that WhatsApp does not store biometric data on your fingerprint. Use the Android API developed by Google that allows you to use the fingerprints previously stored on your smartphone.
The fingerprint lock came to the WhatsApp beta for iOS three months ago, so now that you have reached the beta for Android surely we will see it implanted in the general public version very soon.
