MacOS Notarization on command line unable to create authentication session
couple of things need to be done.
1) manage app specific password(https://appleid.apple.com/account/manage) https://github.com/expo/expo-cli/issues/927
2) try to type all commands manually so that command line should not have escape character(before I tried to copy paste commands)
First try to run this command to make sure your user name and password are correct.
xcrun altool --list-providers -u aaaaaaa@gmail.com -p aaaaaaaaaa
the user name for the account is the apple id username that created the app specific password. (it is not the name of app specific password created. that is just for housekeeping)
