WhatsApp multi-device support is now rolling out to everyone.
The multi-device support is one of the most anticipated WhatsApp features. The feature allowed users to simultaneously use their WhatsApp account on up to four accounts. Moreover, users are not required to have the internet connection active on their primary device to access WhatsApp on other devices. So, ultimately, you don't need your phone to be connected to the internet to use WhatsApp for web or PC.
As reported by WABetaInfo, the stable build of multi-device support is expected to roll out for iOS users this month, followed by an Android release next month. The report suggests that the login process will be faster while keeping things secure and improving the message organization, especially with considerable messages to be downloaded. Do note that you won't be able to access features such as link preview, monitoring live location, stickers and more on the WhatsApp Web.
