WhatsApp's multi-device support: How to use your account in 4 devices

WhatsApp has been updating itself since the day it stepped into the market. These new updates include multiple account support, multi-device support, pinned messages, reply from the lock screen, polls and quizzes, screen share and many more. Earlier, WhatsApp followed the rules that if you wanted to use the application on two different phones, you had to take two different numbers. You can now use the same WhatsApp account on multiple phones at the same time, thanks to the multi-device support, also called the companion mode. No matter which device you choose, either you choose to link your phone to 4 different computers or to 4 different phones, WhatsApp makes it possible.
