This is the email that was sent by zoom and it will affect all zoom users especially if you organise the meetings.

At Zoom customers are our number one priority, and we always strive to bring you the best, most secure video meeting experience in the industry. 

As we have previously communicated, starting September 27th, 2020, we will be requiring that all meetings have a Passcode or Waiting Room enabled. We have designed these security measures to give you control over your meeting security options while keeping the join experience as frictionless as possible.

• For meetings that do not have either a Passcode or Waiting Room enabled by September 27th, Zoom will enable a Waiting Room for you.
• You can customize the Waiting Room experience so individuals within your account, or on an approved list of domains, can bypass the Waiting Room and directly join the meeting.
• You can find meetings that are scheduled without a Passcode or Waiting Rooms by pulling the following report. 
• We have also improved our Waiting Room notifications so the meeting host can now receive a visual and auditory notification that an attendee has entered the Waiting Room.
