WhatsApp already has an option that lets you sign in to your account on four different devices while keeping them all synced. But there is another convenient feature coming soon that will let you keep multiple accounts on a single device instead.
No this is not about having multiple WhatsApp versions to run multiple accounts. Instead, this update will let you use multiple accounts on a single app and let you swap between them at all times too.
Once you log into an additional account from your device, it will be saved in your list of accounts until you sign out of that account. This should allow people to split their personal and professional WhatsApp accounts even if they only have a single device.
The specifics of how WhatsApp will handle notifications from multiple accounts have yet to be revealed. It is possible that a label indicating the account from which a message originates may be introduced, but further details remain unknown at this time.
