Starting as early as December 1, 2022, you must set up two-step verification with a mobile number or authenticator app to sign in to Seller Central. This update will ensure that your seller account remains secure. After you enter your password, you’ll receive a one-time password over SMS on your phone to confirm your sign-in.
If you don’t want to receive a one-time password over SMS every time you sign in to Seller Central, you can go to Login Settings to register an authenticator app for two-step verification.
If you don’t have a mobile number or an authenticator app registered on your account, you’ll be guided through a process to register your mobile number during your next sign-in.
