Hologram issues each user 5 tunnel keys. These can be enabled or disabled using our REST API. To disable an old key so you can make a new one make the following POST request: https://dashboard.hologram.io/api/1/tunnelkeys/id/disable
Tunnel keys are mapped to clients (computers) not devices so you can use one tunnel key for as many devices as possible and access your devices from 5 different clients.
