Zoom has two principle types of security (to make sure authorized persons enter the Zoom session.) One type of security is the use of a passcode. To enter the Zoom session, the user must enter a passcode assigned by the organizer. The other is a waiting room. When a user logs onto the Zoom session, he/she is put into a waiting room. The host of the session receives a message that there is someone waiting. The host then enables the use to enter the session after he/she is validated by name or other means. Open Zoom sessions (like a Bible class) use the waiting room while Memorial Service uses a passcode.
