Zoom security issue

[Nithika]

I was hosting a  zoom meeting. I enabled the waiting room in the meeting. One participant directly   joined  to the meeting and removed me from the host and took host. He did not enter to the waiting room.Did he signed in from my zoom account?

Hi,Nithika

Do you start the meeting as an alternative host and become the host?
If so, if the original host joins, he or she will become the host and you will automatically become the co-host!

as think he found out your zoom id and signed in then as Ohkawa has said you must have been the alternative host.
