WhatsApp today announced a new layer of security for Android users that unlocks apps by fingerprint. In fact, the feature was previously enabled on the iPhone and can be unlocked with face ID or Touch ID. Similar locking features are now available in many similar applications, including the popular encrypted messaging app Signal.
Instant messaging applications have largely replaced SMS sMS and e-mail as the main way for contemporary users to communicate. Although WhatsApp is less popular in the U.S., it is the primary messaging application used in many countries, so it’s important to provide a variety of security options that meet the user’s needs.
