WhatsApp On Up To Four Devices At The Same Time By Mark1199

End-to-end encryption is maintained

WhatsApp On Up To Four Devices At The Same Time By Mark1199. Facebook has announced the launch of the beta of the multi-device capabilities of WhatsApp, which will allow you to use the service on your computer, tablet and mobile phone at the same time and without the need for a direct connection to a smartphone.

The beta, which is only available to a limited group of users, who are already using the beta version of WhatsApp for iOS and Android , allows you to log in on up to four devices at the same time, and use them all at the same time. Therefore, we can start a conversation on the mobile, switch to our computer, and continue it. This is more like what other modern apps offer, although deep down, it is something different.

But this functionality would not be of much use without the other great novelty: we no longer have to have our mobile with the Internet and connected with our account to be able to use it on other devices.

In the current version, if we use WhatsApp Web, for example, we must associate it with our phone and if it stops working (because it runs out of battery, for example), we will lose the connection on the computer. Something that does not make much sense, but that is due to the very way in which WhatsApp works since it was launched so many years ago.

This is one of the most anticipated functions of WhatsApp, confirmed by Mark Zuckerberg himself as one of the biggest changes that the platform has undergone. Although other apps such as Telegram can be used on any device only with our username and password, WhatsApp has the disadvantage of being associated with a specific phone.

Changing that, and keeping security features like end-to-end encryption, hasn’t been easy; WhatsApp leader Will Cathcart has explained this in today’s announcement. The problem has been in maintaining all the functions of WhatsApp, without depending on the connection with the mobile in which we first installed the app. WhatsApp On Up To Four Devices At The Same Time By Mark1199

End-to-end encryption, which guarantees that our conversations are private and not even WhatsApp itself can read them, for example, has been a challenge. In the current system, if we log in with WhatsApp Web on a computer and start a chat with another person, it is actually our mobile that initiates the connection with the other user’s mobile, sending the encryption key necessary to encrypt the text of the messages. From there, it “passes” the connection to the computer so that it can send and receive messages.

With the new system, each WhatsApp client can initiate a connection on their own, generating a unique encryption key. Of course, doing that would mean that we could not continue the conversation with another device, since it would not have the encryption key. One solution would be to store the messages on a server to which all our devices could connect, but that would have consequences for privacy.

To avoid this, Facebook has devised a system in which the encrypted message is transmitted to all the devices on which we are logged in, each one individually encrypted. In this way, Facebook can boast that messages are not stored on its servers , while ensuring that all messages are encrypted. The devices can synchronize the messages between them, and thus we always have the history and our chats accessible.

It’s a curious solution, and something that Mark Zuckerberg is apparently proud of as he commented in an interview a few weeks ago. Other aspects, such as calls and video calls, have also had to be adapted to the new system. WhatsApp On Up To Four Devices At The Same Time By Mark1199

At the moment, there is no release date for all users, but it should not be long if the first tests with real users go well. WhatsApp On Up To Four Devices At The Same Time By Mark1199
