If you are scheduling a meeting where sensitive information will be discussed, we
recommend leaving Enable join before host (found in the Meeting Options section while
scheduling a meeting on the webpage, or in the Advanced Options if scheduling via
the Zoom application) turned OFF. See Zoom's Join Before Host help page for more information.
The join before host option can be convenient for allowing others to start or continue
with a meeting if you (the host) are not available. In order for other attendee to
become the host and gain full control of the meeting, the Claim Host option located
at the bottom of the participants list must be used. When using this option, the
host key is required. The host key is located on the host's main profile and has
to be shared with the participant that will use this option.
As an alternative, we recommend assigning an Alternative Host
It is still possible for a meeting to start with you (the host) even with Join Before
Host disabled. If you have given someone Scheduling Privilege (which allows them to schedule meetings on your behalf), when that person joins a
meeting before you, the meeting will start and they will be made the host. This is
typically not a problem, as our recommendation to disable Join Before Host is based
on preventing unwanted/uninvited participants from hijacking a meeting. After you
join, the role of Host can be reassigned to you.
