Unable to authenticate with Git Bash to Visual Studio Team Services

Question

I am unable to run any commands against my remote repository at Visual Studio Team Services (VSTS) because authentication fails.

I am able to do pulls, etc. through

Answer 1

You need to enable Alternate Authentication Credentials if you want to use other Git clients outside of Visual Studio...

To set up alternate creds in Visual Studio Team Services (VSTS), click on your name/icon on the top right -> Security -> Alternate Authentication Credentials

Edit: Add more details about this from VSTS (taken from the alternate credentials screen)...

ALTERNATE AUTHENTICATION CREDENTIALS

Some applications that work outside the browser (including Team Explorer Everywhere command line client and the git-tf utility) require basic authentication credentials. Other applications do not properly handle using an e-mail address for the user name during authentication.

To work with these applications, you need to enable alternate credentials, set a password, and optionally set a secondary user name not in the form of an e-mail address. Please note that alternate credentials cannot be used to sign in to the service from a web browser or outside of these applications.
