Hi Latedev
Thanks for your post, welcome back to the Community Forums!
Sorry to hear you're having issues with your account. To clarify, are you trying to access your My Virgin Media account or email account? Were you requested to add a non-Virgin email address as per our generate app password process?
If so, you'll then need to access your email account with your newly linked email address through the My Virgin Media portal. If you're having issues signing in, you'll need to reset the password through your primary My Virgin Media account.
