Hi @sarahschindler96. Ownership of a Ring device is determined by the email address that is associated with the Ring account. With that being said, it is only possible to have one owner of a Ring Device. You can view any devices that are currently signed into your account by looking in the Control Center in your Ring app.
If you have any other concerns regarding this issues, you can reach out to our support team for further guidance. Please give our support team a call at one of the numbers available here. We’re taking additional steps to protect our team and help reduce the spread of COVID-19, so this has resulted in longer than normal wait times.
