This means, on your local machine, you haven't made any SSH keys. Not to worry. Here's how to fix:
- Open git bash (Use the Windows search. To find it, type "git bash") or the Mac Terminal. Pro Tip: You can use any
*nixbased command prompt (but not the default Windows Command Prompt!) - Type
cd ~/.ssh. This will take you to the root directory for Git (LikelyC:\Users\[YOUR-USER-NAME]\.ssh\on Windows) - Within the
.sshfolder, there should be these two files:id_rsaandid_rsa.pub. These are the files that tell your computer how to communicate with GitHub, BitBucket, or any other Git based service. Typelsto see a directory listing. If those two files don't show up, proceed to the next step. NOTE: Your SSH keys must be namedid_rsaandid_rsa.pubin order for Git, GitHub, and BitBucket to recognize them by default. - To create the SSH keys, type
ssh-keygen -t rsa -C "[email protected]". This will create bothid_rsaandid_rsa.pubfiles. - Now, go and open
id_rsa.pubin your favorite text editor (you can do this via Windows Explorer or the OSX Finder if you like, typingopen .will open the folder). - Copy the contents--exactly as it appears, with no extra spaces or lines--of
id_rsa.puband paste it into GitHub and/or BitBucket under the Account Settings > SSH Keys. NOTE: I like to give the SSH key a descriptive name, usually with the name of the workstation I'm on along with the date. - Now that you've added your public key to Github and/or BitBucket, try to
git pushagain and see if it works. It should!

For registering newly created SSH keys, you must register your keys (private keys) to SSH agent, instead of requesting shell access of GitHub.
