Although users can use the messaging service on several platforms, and still need to connect them to a smartphone, mainly because of the way WhatsApp handles end-to-end encryption (E2EE). That will change and eventually you will no longer have to have a phone nearby to use WhatsApp on the web, macOS, Windows or portal.
From today, WhatsApp will invite users to try their own . You will be able to use the service on your phone and up to four other devices (provided they are not phones either). WhatsApp will try to access multiple devices with a small group of people from its beta program. He will be able to turn off the beta later. With the help of these users, WhatsApp will optimize the experience of multiple devices and add some more features before presenting it more widely.
Although many users have requested support for multiple devices, WhatsApp took some time to accomplish this. He built a system that retains end-to-end encryption, while allowing people to sync data such as contact names, archives, and starred messages on all devices.
So far, the WhatsApp smartphone app has been a key service channel. Other platforms such as the web and computer applications maintain a consistent, secure connection to the phone application and map content. But if your phone battery runs out or there is a problem with the smartphone app, you cannot use WhatsApp on other platforms.
Through the beta version of multiple devices, each device will have its own identification key. Currently, users have one identity key (i.e., the one on their phone) to handle encrypted messages. WhatsApp has developed systems says it will keep eavesdroppers trying to add devices to the account and minimize how many times people need to verify their identity on different devices. You will also have control over the connected devices and see which ones are connected to your account.
In addition to messaging, WhatsApp will have E2EE support for voice and video calls as part of a multi-device beta. There will be no impact on the way WhatsApp handles cloud backups.
Troubleshooting E2EE support on user devices can be inconvenient given that only the devices to which messages are sent and from which they should be able to decrypt. Apple seems to have found the answer – iMessage supports E2EE on Apple devices. Although Telegram works on multiple devices, its E2EE access (Secret Chats) . Like the current WhatsApp setting, Signal’s desktop app is also needed connect to a smartphone to send and receive messages.
