Host: The user that scheduled the meeting. They have full permissions to manage the meeting. There can only be one host of a meeting.
Co-host: Shares most of the controls that hosts have, such as managing attendees. The host must assign a co-host during the meeting. Co-hosts cannot start a meeting.
Alternative host: Shares the same controls as co-hosts, but can also start the meeting. Hosts can assign alternative hosts when they schedule a meeting.
Alternative hosts must have PSU credentials
In your PSU Zoom account, an alternative host must be a PSU community member and have an Odin username to login and authenticate with.
