I use the meeting of the paid plan.
Can you not refuse access with an account name or a device in the other party connected to?
If a sentence is wrong because I am weak in English, I am sorry.
Hello @saaatoooruuu
Thank you for your message.
Currently, it is not possible to block specific accounts or devices from a Blizz meetings.
You can, however, create a password-protected meeting using the Scheduler found in Blizz
Select Scheduler on the left side of the Blizz application
When you create a new scheduled meeting, you will find the optional password field
The optional password field, found below the date selection
Enter a password in this field, and only participants who know the password will be able to join the meeting!
*Please Note* Scheduled meetings have their own unique meeting IDs, and will not use the one associated with your account.
I hope this helps!
