WhatsApp is testing multi-device synchronization that does not require a mobile phone


although Users can use messaging services across multiple platforms, and they still need to connect to a smartphone, mainly because of the way WhatsApp handles end-to-end encryption (E2EE). This situation is about to change, and eventually you will no longer need a nearby mobile phone to use WhatsApp on the web, macOS, Windows or Portal.

Starting today, WhatsApp will invite users to try . You will be able to use the service on your mobile phone and up to four other devices (as long as they are not mobile phones either). WhatsApp will try the multi-device approach with a small group of people from its Beta program. They can opt out of the beta version in the future. With the help of these users, WhatsApp will optimize the multi-device experience and add more features before a wider launch.

Although many users have been requesting multi-device support, WhatsApp took some time to achieve this goal. It builds a system that retains end-to-end encryption, while allowing people to synchronize data such as contact names, files, and starred messages across devices.

So far, the WhatsApp smartphone application has been an important channel for the service. Other platforms (such as web and desktop applications) maintain consistent, secure links and mirror content with mobile applications. However, if your phone battery runs out or there is a problem with the smartphone application, you will not be able to use WhatsApp on other platforms.

Through the multi-device test version, each device will have its own identity key. Currently, users only have one identity key (that is, the identity key on their mobile phone) to process encrypted messages. WhatsApp has development system It says it will stop eavesdroppers trying to add devices to user accounts and minimize the number of times people need to confirm their identities across devices. You can also control the connected devices and see which devices are associated with your account.

In addition to messaging, WhatsApp will also provide E2EE support for voice and video calls as part of the multi-device beta. The way WhatsApp handles cloud backups will not be affected in any way.

Solving the problem of cross-user device support for E2EE can be tricky, because only the device sending the message can decrypt them. Apple seems to have found the answer-iMessage supports E2EE across Apple devices. Although Telegram works on multiple devices, its E2EE method (secret chat) . Like the current settings of WhatsApp, Signal’s desktop application also requires Connect to smartphone Send and receive messages.
