Ruuvi gateway how to change ownership?

Hello,
I wish to passdown my ruuvi gateway to my father, how can I unregister it from my account?

Hello,

Gateways are not registered to accounts, every Gateway relays every Tag in range to Cloud. If you need to transfer ownership of Tags, unclaim / remove them in Ruuvi Station app or WebUI and they become free to be claimed by your father.
