WhatsApp is rolling out a highly requested feature that will allow users to manage multiple accounts on a single phone, with iOS beta testers already seeing the update.

• The new feature will enable independent profiles, each with its own chat history, privacy controls, and backup settings.
• Security will be maintained through App Lock, requiring re-authentication via Face ID or password for switching between accounts.
• This update follows WhatsApp's recent expansion in the EU and reports of a potential vulnerability exposing up to 3.5 billion phone numbers.
