Starting March 28, 2024, Seller Central will require identity verification via a mobile number or an authenticator app for sign-in, enhancing security against fraudulent access. Users without two-step verification set up will be guided to add a mobile device upon sign-in. Alternatively, users can opt for an authenticator app through “Login Settings” for convenience and improved security, especially for accounts with multiple users or when cell service is unavailable.
Additional information and troubleshooting for two-step verification can be found on the help pages.
