How to Fix Zoom Error 3113 (Security Settings Required)

Zoom Error Code 3113 occurs when you attempt to launch, host, or schedule a Zoom meeting that fails to comply with Zoom’s security requirements.

This guide explains the technical reasons behind the 3113 error and provides step-by-step methods to update your meeting configurations to satisfy the security criteria.

What Causes Zoom Error 3113?

Zoom requires that all meetings be secured with at least one access control layer to prevent unauthorized attendees (commonly referred to as “Zoom-bombing”).

Error 3113 is triggered when:

1. No Passcode Enabled: The meeting settings do not require a passcode to join.
2. No Waiting Room Enabled: The meeting does not redirect unauthenticated participants to a waiting area before admission.
3. Outdated Scheduler Settings: External calendar integrations (such as Google Calendar or Outlook schedulers) send an outdated API payload that lacks these security flags.

If both the Passcode and Waiting Room security parameters are set to false, the Zoom API rejects the session and returns Error 3113.

Resolving Steps for Meeting Hosts

Only the host or the account administrator who scheduled the meeting can resolve this issue. If you are a participant experiencing this error, you must contact the host and request they update the meeting configuration.

Method 1: Enable Passcode or Waiting Room on the Zoom Web Portal

This is the most reliable way to modify meeting parameters directly on Zoom’s master servers.

1. Navigate to the Zoom Web Portal and sign in.
2. In the navigation panel, click Meetings.
3. Under the Upcoming tab, hover over the meeting generating Error 3113 and click Edit.
4. Scroll down to the Security section.
5. Ensure at least one (or both) of the following options are checked:
   • Passcode (You can customize the passcode string or accept the auto-generated one).
   • Waiting Room
6. Click Save at the bottom of the page.
7. Send the updated meeting invitation link (which now contains the encrypted passcode) to your participants.

Method 2: Adjust Global Account settings (For Administrators)

If you are an IT administrator managing Zoom for a company or school, you can enforce these rules globally to prevent users from triggering Error 3113.

1. Sign in to the Zoom Web Portal as an administrator.
2. In the navigation menu, click Account Management, then select Account Settings.
3. Navigate to the Security tab.
4. Locate the following settings and toggle them to Enabled (blue):
   • Require a passcode when scheduling new meetings
   • Waiting Room
5. Click the Lock icon next to these settings to prevent users from disabling them locally.

Method 3: Reset Calendar Integration Plugins

If you schedule meetings via Outlook or Google Calendar, the local calendar cache might contain outdated scheduling rules that conflict with Zoom’s servers.

taskkill /f /im outlook.exe
rmdir /s /q "%appdata%\ZoomOutlookPlugin"

killall Outlook 2>/dev/null
rm -rf ~/Library/Containers/com.microsoft.Outlook

Summary Checklist for Quick Reference

• Verify Host Identity: Ensure you are logged into the correct Zoom account that originally scheduled the meeting.
• Check Security Options: Confirm that either Passcode or Waiting Room is checked in the meeting settings.
• Resend Invite Link: When you enable a passcode, the meeting link URL changes to include an encrypted hash (e.g., ?pwd=...). You must distribute the updated link to participants.
• Update Calendar Plugins: Ensure your Google Calendar add-on or Outlook add-in is updated to automatically append security credentials.
• Check App Updates: Update the Zoom client to the latest version to ensure the scheduler UI correctly enforces security checks.
