Authorization and Authentication
This section describes the available options for authenticating and authorizing a third-party client application in Hub or YouTrack.
|Log in to Hub|
Read this if your YouTrack Server installation is connected to an external Hub service, or you develop an application for another team tool that uses Hub for user authentication and authorization.
|Log in to YouTrack|
By default, YouTrack Cloud and YouTrack Server both use a built-in Hub service to authorize and manage users, groups, and access permissions. Refer to this section if you are working with a default YouTrack configuration.
