Currently I have 3 Roku devices, 2 sticks and 1 speaker. My girlfriend has a stick (not on my account) we want to use it in my house. The stick will not allow me to log into my account, how can I change this stick or add it?
Thanks for this. I'm not on it right now so is it in SETTINGS where I can reset it?
Settings->System->Advanced system settings->Factory reset

Keep in mind that if your girlfriend has any subscriptions through Roku you/she will lose access to them on that device once you link it to a new Roku account and the charges will continue. If she's not sure, she can check her subscriptions at https://my.roku.com by logging in with the same email address that's currently displayed on that device under Settings->System->About.
What does she look like and what size rack?
