To allow people to join your Zoom meeting without needing a passcode (and without requiring them to have or sign into a Zoom account — i.e., they join as guests), follow these key points based on current Zoom rules (as of 2026).

Zoom requires at least one security layer for every meeting to prevent abuse (like Zoombombing). You cannot have a meeting with neither a passcode nor a Waiting Room (or other restrictions like "only authenticated users"). If you disable both, Zoom auto-enables the Waiting Room.

The closest setup to "no passcode needed" is to disable the passcode but keep the Waiting Room enabled. Participants can then click the join link and enter directly (after you admit them from the Waiting Room if you choose), without typing any code.

Step-by-Step Setup (Recommended: No Passcode + Waiting Room On)

1. Sign in to the Zoom web portal at https://zoom.us/signin (or via the app → Settings → web portal link). You need a Zoom account to host meetings.

2. Go to Settings (left menu) → Meeting tab → Security section.

3. Adjust these:

   • Require a passcode when scheduling new meetings → turn OFF (disable it). This stops automatic passcodes on future meetings.
   • Require a passcode for instant meetings → turn OFF if visible.
   • Waiting Room → turn ON (this is usually the fallback security if no passcode is set).
   • (Optional but common) Only authenticated users can join meetings → turn OFF unless you specifically want to force logins.

4. Save changes. These apply to new meetings (and often existing ones if you edit them).

5. When scheduling a new meeting (or editing an existing one):

   • Uncheck Passcode / clear any passcode field so it's blank.
   • Make sure Waiting Room is enabled (it may auto-enable if passcode is off).
   • Enable Join before host if you want people to enter even if you're not there yet (they'll wait in the Waiting Room until you start/admit).
   • Save → copy the join link (it embeds everything needed).

6. Share only the join link (not just the Meeting ID). Participants click it → they join as guests (no account/login needed) → go straight to the Waiting Room (no passcode prompt) → you admit them from the participants list.

Alternative: Keep Passcode but Make It "Invisible"

• Leave passcode on, but check Embed passcode in meeting link for one-click join.
• Share the full join link → participants click and enter automatically (no manual passcode entry), still no account required.

Important Notes

• No way to have truly zero security (no passcode + no Waiting Room) on standard Zoom accounts — Zoom enforces one layer.
• If your account is managed (work/school), an admin may lock settings — check with them if options are grayed out.
• Guests (no Zoom account) can always join via link or zoom.us/join + Meeting ID (and passcode if required) — they just select "Join as guest" or skip sign-in.
• For public/open meetings, Waiting Room gives you control to screen/admit people.

This setup lets non-account users join easily as guests while keeping basic security. If you run into locked settings or different options, check your account type (free, Pro, etc.) or Zoom's support page for "meeting passcodes" / "Waiting Room".
