If you want to connect to the Visual Studio Online API you are going to need some credentials in order to connect. That’s right, where do you expect to store your MSA for connecting? Do you expect to add it to the windows credentials store? What about having the user manually add it? Both these options suck… so introducing the VSO Service Credential Viewer.

The VSO Service Credential Viewer connects to your account on VisualStudio.com and, using your MSA credentials, it retrieves credentials that you can use for an automated service to connect and authenticate correctly.

How it works

Once you have authenticated as a TFS Collection Administrator (VSO Account Owner) to your VSO collection we use the Access Control Service to provision a service identity that you can use for unattended connections to Visual Studio Online.
