I'm trying to solve this problem since a long time, every execution I perform on TF.exe command, is throwing TF30063 exception, when i'm the admin and the only user of my TFS.

Problem: Try to execute this in a clean machine, without any visual studio user logged in on visual studio, IMPORTANT: also remove your user from windows credentials.

tf.exe workspaces /computer:mycomputer

enter image description here

This modal pops up prompting for credentials, but I need something to be run in a command window without user interference, so checking help I see that you could send /login:user,password

Then, again let's try with that in the command:

tf.exe workspaces /computer:mycomputer /login:[email protected],MyPassword

And now, I get the following exception:

TF30063: You are not authorized to access xxx

BUT, and for the last, if I login on that popup (which I don't want to do because it will be a remote build service) suddenly all commands works fine.

What is the point of having /login command if is not useful here? is there a way to perform this login without prompt?

Thanks for the help!

  • I also tried to add in the Windows Certificates, using cmdkey.exe, the acount that is trying to log in, but this was not also useful.

It seems you are using VSTS, not on-premises TFS. Usually /login option can be used on on-premises TFS, we use the /login option to specify the Team Foundation Server user account to run a command.

If you want to use on VSTS, you need to get a OAuth token, and specify /loginType:OAuth. The command line is:

tf workspaces /collection:https://xxxx.visualstudio.com /loginType:OAuth /login:.,[OAuth token]

  • Indeed, i´m using VSTS, I was not aware of this difference, but I see your point, probably the command that I ran will work if I have a on-premise TFS. But anyway, do you know how could I authenticate to my VSTS by command line?

  • You need to get a OAuth token by following this article, specify /loginType:OAuth and use the OAuth token as password in the command line: tf workspaces /collection:https://xxxx.visualstudio.com /loginType:OAuth /login:.,****

  • Or set up a PAT if you don’t want to use OAuth.

  • This looks promising, I will give a try and get back to mark as answer if it works. Thanks!

    The instructions for getting an OAuth token (in the OAuthWebSample) require deploying an app to Azure Web Apps. Isn't there a better way to get a token? I find it unreasonable to have to deploy a web app to public hosting to get the token I need to authenticate a command-line tool to pull from source control (as well as quite impractical given the approvals I'd need do it).

I know it's been very long since this thread is opened but I recently experienced the same issue and resolved it by following the below steps. This maybe helpful for people who will get stuck with this issue in future...

Yes, I have faced the same issue and was able to resolve the issue finally :)

The problem is that tf.exe command with the switch "/login:username,password" works as expected with the onprem versions, however you have to use OAuth for saas version. Please find the below example command for saas version for your reference.

tf workspaces /collection:https://dev.azure.com/OrganizationName /loginType:OAuth /login:.,OAuthtoken

To generate the OAuth token you should be using the following article as a reference.

https://learn.microsoft.com/en-us/azure/devops/integrate/get-started/authentication/oauth?view=azure-devops

Hope this helps someone at some point of time :)
