Can't remember what it is called, but I used to have that Google authentication code generator app on my phone which would be used to enter a special code for the 2-step Google authentication system.
My phone has been damaged, so I have a new one now. But I can't log into Google because I don't have that authentication app installed on my phone, and I can't install that authentication app on my phone because I need the authentication code.
What can I do?
