The Account Center is a single place that allows users to manage logins to Facebook, Instagram, and (even) Meta Quest. Meta today announced that WhatsApp is joining the list of supported apps, allowing you . Also, you can use to log back into your WhatsApp account.
Meta announced the change today, but it will be a while before WhatsApp support is added to everyone's Account Center, so patience may be required.
