WhatsApp Expands Authentication Options: More Secure Chats Ahead?

WhatsApp is introducing an improved app lock feature in its latest beta for Android devices. The new feature will accept alternative unique identifiers, such as passcodes, in addition to biometric authentication. This change allows devices without biometric sensors to use the app lock feature, making it more accessible to a wider range of users. Additionally, WhatsApp is increasing the limit of how many chats can be pinned at once, moving the limit from three to five. The company is also testing a new in-app label to indicate when a chat room has end-to-end encryption (E2EE). The label will appear underneath the contact and group name and serve as a visual confirmation that outside forces cannot read what is being discussed or listen to phone calls. Finally, the EU passed the Digital Markets Act in 2022, which implemented new rules forcing major messaging platforms to allow communication with third-party services, and WhatsApp published a report on its Engineering at Meta blog detailing how interoperability will work in Europe.
