MeshCentral is free, open-source, and supports several types of Multi-Factor Authentication natively.
Here's an example image of what MeshCentral looks like when accessing a Desktop:
The Tech Department uses MeshCentral to access our servers.
Where there is specific need, we give access to specific machines to people like contractors, or others throughout the district.
Unless you are a part of that very small group with specific need, and have received credentials from the Tech Department, you do not have access to MeshCentral.
