You can set up a password for your meeting when scheduling it via the Scheduler.

You can also lock running meetings to avoid that others can join a running meeting. I added some more info here: https://community.teamviewer.com/t5/Support-for-schools-and/FAQ-Using-blizz-in-class/td-p/88243#toc-...
Have a great day,
Thank you Esther,
however, it is not possible to lock a meeting with a password without scheduling it?
That seems rather unsafe. Can you please add that option for the next update?
Thanks for your feedback.
I am happy to forward your suggestion to our product team 👍
Unfortunately, I can not say when or whether this feature will be implemented, but I inform the team about it.
Also: My recommendation is to lock every meeting via the LOCK once all participants are in the meeting/call.
