MS Visual Studio online was something new to me. It definitely is targeted for those using Visual Studio as product, however for those of us that us Atom or Sublime we’re a bit stuck.
VSS online doesn’t support ssh , so don’t bother looking for it.
What you’ll need to do is:
1. Setup alternate credentials (username and password ) This can be done in profile window
2. git clone http://<yourproject>.visualstudio.com/….
3. git config credential.helper store
4. Make changes and push, it will prompt you for credentials but they will be saved and you won’t be prompted again
ps. keep in mind that credentials are saved in a file (hidden) and shouldn’t be exposed, hence the alternate credentials so that your MS account isnt exposed.
