The wait is over: the Whatsapp will start providing access to an account on more than one cell phone at the same time. This Wednesday (14), the messenger announced the start of testing the feature that will allow the use of the same credential in up to four different devices. End-to-end encryption will also be maintained.
The feature will begin rolling out after Facebook CEO Mark Zuckerberg and WhatsApp head Will Cathcart have confirmed the new feature. In an interview, executives said the new feature would be released to users of the app’s beta version within two months.
Just over a month after confirmation, the tool is about to arrive at WhatsApp Beta. According to the messenger, it will be possible to use an account on up to four different devices at the same time. In addition, message history will be synchronized across all authenticated devices.
WhatsApp can be used on up to four devices
The tool will make a big change in the way the messenger works. Currently, users need to keep their cell phone turned on and connected to the internet to use the messaging app via other platforms. Otherwise, options for accessing the account from the computer, such as WhatsApp Web, do not work.
With the new feature, each device will work independently. This means that, like the Telegram, you will no longer need to keep your cell phone close or turned on, as each device will have its own identification. Altogether, it will be possible to connect the account on up to four different platforms.
Conversations will also be available on all authenticated devices. According to the messenger, both the message history and the application’s state data will be synchronized between the devices. “All of this data is synced and encrypted end-to-end between their devices,” they said.
End-to-end encryption will be maintained
The task, however, was not simple. The messenger stated that “the challenge was to maintain a secure user experience across multiple devices without having to store people’s private messages on our servers in new ways.” Even so, end-to-end encryption, one of the service’s flagships, will remain.
The messenger explains that, now, each device will have its own identification. “The WhatsApp server maintains a mapping between each person’s account and all their device identities,” they said. “When someone wants to send a message, they get the device list keys from the server.”
Those responsible for the app also took steps to prevent conversations from being spied on by a malicious or compromised server. “We’ve also added additional controls and protections over which devices are tied to the account,” they said. In other words, in addition to the QR Code, which is already known to those who use WhatsApp Web, it will also be necessary to use biometrics to access the account on another platform.
Initially, the feature will be available to a “small group of users” of WhatsApp Web. “WhatsApp will continue to optimize performance and add features before making this new feature more widely available,” they said. “Users who choose to participate in this test can always opt out.”
It is not yet known when the news will reach the final version of the messenger.
