WhatsApp tests the possibility to secure the app with your fingerprint. If someone else is on your smartphone, he or she will not be able to see your WhatsApp conversations.
Protect WhatsApp with fingerprint
The latest test version of WhatsApp (2.19.3) was released yesterday in the Play Store and contains one major innovation, as discovered Twitter user WABetaInfo . In the settings of the app under ‘privacy’ now the option ‘Authentication’.
The accompanying text (‘fingerprint’) betrays that WhatsApp is working on the possibility to secure the app with your fingerprint. The source says that the feature is not working yet, but that he has got the security method going through a detour. Enabled WhatsApp only opens when you confirm your identity via the fingerprint scanner.
If that is not possible, for example because your finger is wet, you can also enter ‘device credentials’. It is not clear what WhatsApp means by these credentials. Presumably it is a pre-chosen PIN or password that serves as a backup method.
Release date not yet known
According to WABetaInfo, the development of fingerprint protection is still at an early stage. The feature would not work properly yet. When WhatsApp makes the security method available, it is therefore unclear. To be able to lock the app later, you need a smartphone with Android 6.0 (Marshmallow) or newer and of course a fingerprint scanner.
