Forum:Reign of Dragons Logout

My friend forgot his phone at home this past weekend and logged into his RoD account with my phone to get his daily login bonus but now I cant logout of his account so i can go on my account. There are now 2 phones logged into the same account. There is NO LOGOUT picture on the My Page so that is out of the question.

Please help me, now I am loosing my daily login bonuses.
