We currently don't have an option to share your Restore 2 device with another user. Restore 2 was not made to have multiple users like our other products for babies & kids given all of the personal customizations it has.
But, if you share a bedroom with a partner and you would like both you and your partner to be able to control the Restore 2 in your home, just use the same Hatch login credentials as the main user of the device. You will be able to control Restore 2 without any limitations.
