There are divers recommendations from the provider as well as from different sites on how to set configurations and to plan and hold the meetings.

Recommendations from the provider

The provider himself made some handouts with recommendations:

Securing your meetings

From winter semester 2025/2026: Mandatory activation of at least one security feature

When scheduling a new meeting in Zoom, you must select at least one of the three security features explained below. We recommend always setting at least a passcode.

If you didn't select an option during planning, the waiting room will be automatically activated and set up for your meeting. Please consider in advance which security features are suitable for your event, taking into account the event size and target audience. Read more about this in the following section.

Using the personal meeting id is not recommended

It is recommended that the personal meeting id, which directly belongs to an account, is never used as a meeting id.

Always set a password for meetings

If only the knowledge of a meeting id is required to enter a meeting unwanted persons can gain access very easily. The meeting id is due to automated creation very easy to guess.

Consider to enable access only with a login

If all participants of the meeting do have an account in the zoom entity of Kiel University and obviously know their password, you can enable the option called
'Only authenticated users can join meetings'. Then the meeting id and the password are not enough but a login with a zoom account is required, mostly with the account in the identity provider.

This option only should be used if it is ensured that all participants meet the requirements mentioned above.

How to enable this option for your event and what to consider can be read on the following support site

Participation in meeting only with login

Use Waiting Rooms to regulate access to your meetings

By enabling waiting rooms for a meeting, you can specify who should enter the meeting directly and who should first enter a so-called waiting room, from which they must then be admitted.

Using waiting rooms

More control over participants by registration

You can demand a prior registration for the participation in a meeting. This gives you more control over the list of participants. Details can be found under https://support.zoom.us/hc/en-us/articles/211579443-Registrierung-f%C3%BCr-Meetings
