I'm a collaborator on a private Github repo (owned by someone else), and although I have added an SSH key to my own GitHub account which allows me to authenticate when accessing my own repositories, it always asks me for my password when I try to access the repository on which I am only a collaborator.

Do you have any idea why it doesn't authenticate me with my SSH key?

I have tried to add my key as a "deploy key" to the shared repo itself, but GitHub always rejects my submission, with the error message "Key is already in use.".

My remote looks like the following:

$ git remote -v
origin  https://example-user@github.com/example-owner/example-project.git (fetch)
origin  https://example-user@github.com/example-owner/example-project.git (push)

You've added the github repo as HTTPS instead of via SSH, your URL should look something like this


If you check the right of the repo on github, you should see options to get the links via HTTPS, SSH, or subversion.
