I created an AGOL account using the Google credentials. When I try to sign in from an internet browser, I am able to sign in. I use the Google+ button.

When I try to sign in through ArcMap, however, this option is not available.

I want to sign in to my AGOL account from ArcMap in order to publish some of the data that I have as a service in my AGOL account. Since I am unable to log in, I am unable to publish the data.
I have tried signing in using my full gmail email address. Also I have tried changing the password or sending a reminder of the username. I have verified that the username and password that I am using are correct.
How do I log into AGOL through ArcMap to publish a service?
Thank you for your assistance.
