Allows someone else to manage the administrative side of the meeting, such as muting participants or starting/stopping the recording.

  • Co-hosts should be assigned during the meeting.
  • There is no limitation on the number of co-hosts you can have in a meeting.
  • Co-host will automatically be the host if the host gets disconnected.

Co-hosts do not have access to the following controls as they are only available as host controls in a meeting:

  • Start closed captioning and assign someone or a third-party to provide closed captioning
  • Start live streaming
  • End meeting for all participants
  • Make another participant a co-host
  • Start breakout rooms or move participants from one breakout room to another
  • Start waiting room (co-hosts can place participants in waiting room or admit/remove participants from the waiting room)

Co-hosts also cannot start a meeting. If a host needs someone else to be able to start the meeting, they can assign an alternative host

Alternative host

Allows you to schedule meetings and designate another NUS Zoom Licensed user to start the meeting if Host who schedules is not able to start the meeting.

  • There is no need to schedule someone who will be Co-Host as Alternative Host. Make them co-hosts in the meeting itself.
  • The meeting will still belong under the Host who schedules account.
    You will not be able to start another concurrent meeting, since Zoom allows each account to only start one meeting at a time.
  • Alternative Host will need to have an NUS Zoom Licensed account. Not for external or Basic account.
  • Alternative Host will receive an email notifying them that they've been added as an Alternative Host, with a link to start the meeting.
  • Alternative Host will need to use the Start Meeting button/link in the email.
    If they cannot find it in the mailbox, search for "invites you to join a Zoom meeting as alternative host" in inbox.
  • Alternative Host does not have access to Polling feature.

Scheduling privilege 

Designed to be used when someone else will do the scheduling; like an Executive Admin, Event Scheduler or Secretarial Duties:

  • The Meeting HOST should first assign or grant Scheduler permission to schedule meetings.
  • Scheduler to create new meeting on behalf of Meeting HOST.
  • The Meeting HOST will not have access to Polling feature. 

     How to use scheduling privileges

    Both you and your manager or colleague should have a NUS Zoom Licensed account first.

    Your manager or colleague should sign in to and grant you you scheduling privileges for their Zoom Licensed Account.

    Ask your manager or colleague to assign scheduling privilege to you:


    1. Go to NUS Zoom Web Portal:
    2. Click on Settings.
    3. Under Other, click the + next to Assign scheduling privilege to.
    4. Enter one or more email addresses in the window, separated with a comma.
    5. Click Assign.

    The next time you schedule a meeting via the NUS Zoom web Portal, you will see a new option called "Schedule For" with a pull-down option with your manager's or colleague's name.
