Incorrect Password Error

[FueledxJarritos]

Using an App specific password on Catalina and iOS 13 it results in an incorrect username/password error. Used copy+paste, so can confirm it's not a typo.

Did you try your "normal" iTunes password? I was told that an app-specific password is not required for AltDeploy. I have been using my "normal" password, and it is always accepted without problems.

App-specific passwords are not supported. You need to use your regular password. You shouldn't have problems with 2 factor authentication since AltDeploy asks you for the 6 digit code if you have 2 factor authentication enabled.

had an issue like this myself, refused to work no matter what I tried, however just worked now.

Make sure your entire EMAIL ADDRESS to login is lower case.
