Greetings @SP17
Welcome to the Roku Community and thanks for posting regarding sharing access to a Roku Smart Home device with another person.
Please be aware that the only way to access a Roku Smart Home device linked to a Roku account is to authenticate the Roku Smart Home mobile app with your Roku credentials for every mobile device.
If you have another inquiry in the future, please don't hesitate to post again in the Roku Community.
Thanks,
Danny
