No, you can only connect to an Airbnb listing through the main host’s account. If you are managing for someone and they are not happy to share their login details with you, you can follow the steps on integrating with Airbnb up to the point where you Generate Client ID. You can copy & paste the URL of the new tab that opens, and send that to the host. Ask them to authorise the integration, and to send you back the token that they are provided with. Use that token to finalise the connection.
