Inviting people to your team
If you are using Cloud connections, to allow others to access your computers remotely, see How do I invite people in to my team to share remote access?
For more about Teams, see What is a team, and how do I add computers and people to it?
Authentication
With Professional or Enterprise subscriptions, System authentication is the default. This means you will need to use the username and password of an account on the remote computer. For more information, see What username and password do I enter when I'm trying to connect to VNC Server?
Important note on Permissions
You need to ensure that the users you want to be able to connect remotely have been given permission (by default, only members of the Administrators group are able to connect). To add other users, see Managing users and session permissions for VNC Server. Failure to do this may result in not being able to connect to your computer remotely.
Enterprise Deployments
If you have an Enterprise subscription and want to deploy, license, and configure VNC Server using Group Policy, see Deploying and licensing VNC Connect using Windows MSIs and Setting up Group Policy under Windows
