Samsung Galaxy 5.0 Player Google Voice I am unable to get my non-gmail Google Account to sync with this machine with the google app market. It would not accept an old gmail account that I already have. To get the app market working at all, I had to create a whole new gmail account I really didn't want or need. I've tried using the Google "Account Authenticator" App. Everything seems to work. I follow the directions here: Installing Google Authenticator - Accounts Help and here: Google Authenticator - Google Apps Help and the app finally ends up saving the 'secret key'. As a side note, I have to say the directions for creating two-step authentication really need a better explanation - maybe even a decent video. It took me a while to figure it out, and I'm pretty tech savvy. When I attempt to login thereafter with Google Voice app using my non-gmail account, I get this: I went as far as typing my password into the username field, cutting it, and pasting it into the password field to be sure it was properly spelled. Even that doesn't seem to make a difference. I can log in fine on my computer. I can even log in from firefox on the android, but not the default browser. It tells me to install the voice app instead. But the voice app won't recognize my email address and valid password. I have a suite of services in the same non-gmail google account, including having paid $20 to transfer my home phone number to google voice. I feel like I'm being penalized because I am not using a gmail account to attempt to log in to the android phone. Surely I've done everything correctly, as suggested in the links. I would be grateful for any suggestions that might allow me to actually get my non-gmail google account up and running on my android device.
