Hi @Mouad_Abdelghafour_AITALI ,
Unfortunately, the Appstore Developer Support team is not authorized to handle account login-related issues. If your account is locked due to Two-Step Verification, please follow the steps outlined in Recover Your Account after Two-Step Verification Fails.
If SMS messages are not working for you, you may use an authenticator app instead. For more details, please see the section Does two-step verification support authenticator apps?.
If you are still experiencing issues, we recommend reaching out to the Amazon Customer Service team and providing a description of your issue.
