Hi @Mahmoud123. This Help Center article here has the information on how to transfer ownership of a Ring Device. If this doesn’t solve your concern, you’ll need to contact our support team. 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. If you are outside of the US, please read our response to COVID-19 here to see how to contact support.
