How is a meeting link with the passcode embedded in it any different than a regular old meeting link? If someone has the link, they can get in, and if not, not. I'm not sure what the passcode-embedded link adds to anything. ?
When you embed the passcode into the meeting link, users are not prompted to manually enter the passcode. If you send the link and passcode separately, the user will click the link to join the meeting, be asked to manually enter the passcode, then can join the meeting or waiting room (depending on your settings). With the passcode embedded, they click the link and join the meeting directly.
If you DON’T embed a passcode, anyone with the 11-digit Meeting ID can get into the meeting whether or not they have the link. When you embed a passcode, only people who have the link can get in. If they only have the Meeting ID, they will be asked for a passcode. Helps avoid Zoombombers and other unwanted attendees. Protects privacy.
