I opened up my hbo max app on my roku tv and a random family members account is somehow signed into on my tv. No, we have never shared information and no, these have only been my devices I purchased from the store itself. This shouldn't be possible and kind of scary. She has used my wifi before but I have no idea how this is possible. Usually it's kind of a pain to sign into the apps as it is. You need passwords and email account plus access to those email accounts to get a code. If anyone could tell me how this is possible it would be great. Kind of scary that anyone could have access to these accounts. Especially when they all have a subscription that we all pay for.

Does the family member have a Roku device linked to the same Roku account as your device?

There have been reports in the past of people seeing the HBO/Max app signed into complete stranger's accounts, but I don't recall seeing an explanation or solution.
