WhatsApp no longer requires a password or PIN code to open, and anyone can access your profile if your phone is unlocked. The company is now trying to solve this problem
Android Authority Reports
WhatsApp is testing the fingerprint verification in the Android app version. After activation, you must scan your finger to open an application using the application icon, pop-up messages or external devices
. You can also use the device identification information (probably your PIN) instead of the fingerprint if you wish. This can be useful if your fingerprint reader is difficult or cracked.
It should be noted that fingerprint authentication in WhatsApp is common. This way, you can not hide certain conversations and contacts on a biometric wall.
WABetaInfo adds that this feature will be available for all Android devices with a fingerprint scanner running Marshmallow or later. The feature is still in the alpha stage of development and several months will pass before its current launch
If you can not wait before, some brands of smartphones already allow you to hide the application by fingerprint . For example, if you have a recently released OnePlus, Samsung or Xiaomi phone, you can already block your apps.
