# External Participant Access

**External Participant Access** refers to the technical and procedural workflows that allow individuals without a university user account (guest users/non-university members) to participate in digital communications, meetings, and video conferences hosted by the university.

## Implementation Methods at Universität Greifswald

The URZ provides two distinct workflows depending on the tool used:

### Low-Barrier Access (Jitsi Meet)
This method is designed for quick, flexible meetings. Access is granted via a shared room identifier. Security is optional and managed via a room password.

### Managed Access (BigBlueButton/Moodle)
This method is integrated into the academic infrastructure and requires a more formal setup:
- **Administrative Layer**: Requires a [[moodle]] course.
- **Authentication Layer**: Uses a **guest access key** to authorize non-university members.

## Comparison of Access Models and Workflows

The following tables compare the two models provided by the URZ based on different source perspectives.

### General Comparison
| Feature | Jitsi / Meet | BigBlueButton (via Moodle) |
| :--- | :--- | :--- |
| **Barrier to Entry** | Low / Immediate | Higher / Administrative |
| **Requirement** | Room Name (+ Password) | Moodle Course + Guest Key |
| **Setup Effort** | Minimal (Create room) | Moderate (Course setup + Key config) |
| **Primary Use Case** | Quick meetings, ad-hoc calls | Structured teaching, formal sessions |

### Workflow Comparison
| Feature | Jitsi Meet | BigBlueButton |
|---|---|---|
| **Account Required** | No | No (for guests) |
| **Setup Effort** | Low (Create room) | Medium (Create Moodle course) |
| **Access Key** | Optional Password | Mandatory Guest Key |
| **Primary Use Case** | Quick meetings, commissions | Teaching, structured events |

## Security Considerations
- **Jitsi**: Security is managed via optional passwords for the virtual room.
- **BigBlueButton**: Security is managed through the Moodle course framework and the distribution of specific guest keys.
