WhatsApp has initiated proper evaluation of multi-device support

According to Facebook, they have initiated the testing of Whatsapp's multiple device chats functionality. The leaks about the WhatsApp feature that allow users to sign in from multiple devices has been roaming in the public from quite some time.

Users can connect to WhatsApp from different devices but those devices should be connected to main device. Like if users simultaneously use WhatsApp on mobile as well as on desktop, their desktop account should be connected to their mobile app through internet connections.

But the updated version enable users to use WhatsApp on multiple devices without needing to connect to the mobile device. The latest multiple device functionality on WhatsApp support this feature. WhatsApp's improved multi-device capabilities is now available in a restricted public beta test, according to Facebook.

With this new capability, it is now possible to sign up on four different devices without worrying about the connection as there is no need to connect the other devices with main mobile phone. This implies that whenever mobile phone stops working or the battery died, this feature will there to save the people. Every side devices now have the capability to connect to the WhatsApp providing the same settings as security, keeping the same degree of security and confidentiality that WhatsApp users have learned to rely on end-to-end encryption.

Furthermore, Facebook claims to be creating innovative technologies that allow them to preserve end-to-end encryption yet still syncing the data between devices – including contact lists, chat histories, highlighted conversations, and much more.

The existing WhatsApp secondary device interface on the web, macOS, Windows, and Portal relies on a mobile application to use it as the main source of extracting all the user’s information and the only device capable of encrypting or decrypting messages, starting calls, and so on. Peripheral devices keep a safe link to the phone and just display its information on their own interface.

Now each device works separately since the launch of multi device chatting feature. The WhatsApp service keeps track of each user’s profile and all of their devices identifiers. Whenever anyone desires to send out a message, the website gives them their device list details.

Facebook had successfully devised a system that allows users to add devices to their accounts without their knowledge employing enhanced security codes and Automatic Device Verification, preventing a malicious or hacked server from listening in on their conversations. This technique enables devices to immediately develop credibility with each other, such that a user just requires to check some other person's passcode when they re-enter their complete profile instead of every time they attach a new device to existing account.

Previously, to link to a new device, user is prompted to scan a QR code given on the secondary device by using mobile phone but now they also have to verify via biometric source. Facebook intends to start with a limited number of users from their preexisting beta version to assess the service. They would try to improve functionality and introduce a couple more functions before gradually putting it out to a wider audience.
