amazon u. s. a not allowing sign in

Question

Android deliveries is now being challenged when trying to sign into Amazon. I get a message in deliveries that there are no new orders. Shortly after I get a text message from Amazon that someone tried to access my account. I then tell Amazon I approve the sign on and it is approve. But by then deliveries goes out again to Amazon and the process is repeated. This just started happening this week.It makes it impossible to use this feature. Please fix if possible.

I was able to update Deliveries by turning on 2FA and then adding the authenticity code number at the end of password. The times i tried to sign on before that but failed 2FA was not turned on.
