I cannot add my SSH key to my account or at project level because of this: "Someone has already added that key as an access key to a repository." Note that I am able to add SSH key into specific repository.
I have checked all the places (company user, all the repositories I see etc.) but this key is not associated to none of the repositories nor users I know of.
I have tried to SSH bitbucket.org, but is does not say any details:
ssh -T git@bitbucket.org
authenticated via ssh key.
You can use git to connect to Bitbucket. Shell access is disabled
Could anybody please suggest/help where the SSH key is being used?
No, using multiple SSH keys is not an option.
