What it means
A meeting passcode is a shared secret required to enter or included in some invitation links. Waiting Room holds joiners until the host admits them. Zoom may require at least one security option, but the two controls solve different problems. A passcode copied with a forwarded link can reach unintended people; a Waiting Room can still give the host an opportunity to question an unexpected guest. Neither identifies someone solely from their displayed name.
A real-world example
A confidential meeting's link and embedded passcode are pasted into a group chat. Unknown people try to join. With Waiting Room, the host can leave them outside while verifying who was actually invited.
What to do
Use a controlled invitation, enable Waiting Room for sensitive sessions, inspect bypass rules and test admission with a secondary account. Keep the passcode out of public posts. Verify high-risk attendees through a previously known contact route.
The distinction that matters
Waiting Room is not a substitute for a passcode where policy requires one, and a passcode is not the same as authenticating a person's identity. Some signed-in account members or specified domains may bypass Waiting Room depending on its configuration. A participant admitted by mistake can still see and hear content until removed. Locking the meeting after expected guests enter stops new joins but also blocks legitimate late arrivals. Choose a combination based on the audience and have a plan for exceptions.
