Add your SSH key to the config file

• Open (or create) a config file

$ touch ~/.ssh/config && notepad ~/.ssh/config

• Add this to the config file

Host github.com
  HostName github.com
  User git
  IdentityFile ~/.ssh/github
  AddKeysToAgent yes

• Copy the SSH public key to your clipboard

$ clip < ~/.ssh/github.pub

• Go to https://github.com/settings/keys
• Click on New SSH key
  • enter a name for the key (e.g. Laptop YourName)
  • and paste the copied key and click on Add SSH key

Test your connection with GitHub

• Open a new Git Bash window and execute this command:

$ ssh -T github.com
Hi userName! You've successfully authenticated, but GitHub does not provide shell access.

Update existing repo to use SSH

• Check how your repo is set up:

$ git remote get-url origin

• If this shows a URL like this, you have to update the URL

https://github.com/username/repoName.git

• Update your (old) URL to use SSH instead:

$ git remote set-url origin [email protected]:username/repoName.git

• Check how your repo again:

$ git remote get-url origin

• If the result is like this, you're ready to go:

[email protected]:username/repoName.git
