# Moodle BBB Guest Access

**Moodle BBB Guest Access** is a specific configuration within the Moodle integration of [[bigbluebutton]] that allows individuals without a university account to participate in a web conference.

## Functional Scope
Guest access is highly restrictive. External participants are granted access **only** to the specific BigBlueButton session for which they have the link and password. They are strictly prohibited from accessing any other course content, documents, or Moodle activities. For any broader access to course materials, a [[zentraler-nutzeraccount]] is mandatory.

## Key Features
- **Guest Credentials**: The system automatically generates a unique meeting link and a password.
- **Waiting Room Function**: Instructors can enable a setting that requires a moderator to manually confirm the entry of guests, effectively creating a security waiting room.
- **Automated Distribution**: Moodle allows instructors to send the necessary access credentials directly to guests via email.

## Technical Constraints
- **Password Persistence**: Once a BBB activity is created, the guest password is fixed. It cannot be edited. If a password change is required for security or administrative reasons, the instructor must delete the activity and create a new one.

## Configuration Steps
1. Enable editing mode in the Moodle course.
2. Add a **BigBlueButton** activity.
3. Enable **Guest Access** (Gastzugang) in the settings.
4. (Optional) Enable moderator confirmation for the waiting room.
5. Use the **Add Guests** (Gäste hinzufügen) button to manage and distribute the link and password.
