Application Loader

I am having issues logging into applicaiton loader. I have talked to support and they told me that they are not able to help me because they have done everything that they know how to do. I am using 2F Auth. and Application Loader forces you to use app specific passwords for that. When I generate a password, it tells me that the password was incorrect. After this happened I turned off 2FA and tried logging in with my regular password and it said that my password was incorrect. I did change my password fmor the time that I downloaded XCode and currently. So I believe that may be a cause, but no password that I have ever had works. I am not sure what forum to place this in so I chose a random XCode forum name. Thank you, Cameron
