Can't log into Android App

When I log in at my computer I used “Google+” to sign up and log into my account, but when I try to use the app on my device I don’t get the option to sign in using Google+ and it’s requesting a password.

I went to my settings here to try and set/reset my LingQ password but it’s not allowing me to do that because I log in via Google+.

Am I alone with this problem and are there any solutions because I’d really hate to be tied to my computer to use the program.

@joenewbie When you go to the Account Settings > Account tab, is there a username in your Username field? If so, and you have a password entered there, you should be able to log in. Is this what you have tried to do already?
