WhatsApp has recently introduced a new feature called “Multiple Accounts,” allowing users to log in to and switch between multiple accounts on the same device. This feature is limited to users who already have multiple accounts. Creating a new account still requires a separate phone number and SIM card (e-SIM is also supported). Once the account is created, users can easily add it by accessing the Settings page in WhatsApp and selecting “Add Account.”
TLDR: WhatsApp now allows users to log in and switch between multiple accounts on the same device. Users can add existing accounts, but creating new ones requires a separate phone number and SIM card. Just access the Settings page and select “Add Account” to get started.
