WhatsApp has launched a new security feature that aims to help prevent account takeovers.
This feature is officially called Device Verification.
- Device Verification aims to block the threat actor's connection and allows the target to use the app without disruption.
- The feature creates a security token and stores it locally on the device. By doing so, the token can help identify the validity of a message retrieval request from a specific WhatsApp account.
- The client side is required to send the security token every time it connects to the server.
- On the other side, the security token is updated every time it retrieves a WhatsApp message.
- Device Verification is currently available for all Android users, while iOS users will be able to use the feature in the near future.
