Hi, @jamalnuman –
In general, one of the following security options must be enabled for meetings and webinars:
- Passcode
- Waiting Room
- Authentication (being logged in from a valid Zoom account – can be paid or free account)
With proper security settings in place, some of these can be bypassed. For example, if two user accounts are in the same organizational account, then an attendee in that organization can bypass the Passcode requirement to attend a meeting scheduled by another organization member on the organization’s account.
It is not possible to just let anyone and everyone into your meeting – some form of security is generally required. The easiest way around this is to select using Passcode, and send attendees the long-form Join Meeting link with the Passcode embedded in it. The attendees simply click the link, and they are in.
