GitHub Add SSH

Copy the SSH Public Key

In the previous chapter, we generated an SSH key pair.

Now, use the clip < command to copy the public key to your clipboard:

Example

[user@localhost] $

clip < /Users/user/.ssh/id_rsa.pub

Go to GitHub, navigate to the top left corner, click on your profile, and select “Settings.”
Then select “SSH and GPG keys” and click the “New SSH key” button.
Enter a title, paste the public SSH key into the “Key” field, and click “Add SSH Key.”
You will be prompted to enter your GitHub password.
Once authenticated, you will see your new SSH key listed.

Test SSH Connection to GitHub

Now we can test our SSH connection to GitHub:

[user@localhost] $

ssh -T [email protected]
The authenticity of host ‘github.com (140.82.121.3)’ can’t be established.
RSA key fingerprint is SHA256:nThbg6kXUpJWGl7E1IGOCspRomTxdCARLviKw6E5SY8.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added ‘github.com,140.82.121.3’ (RSA) to the list of known hosts.
Hi code7school-test! You’ve successfully authenticated, but GitHub does not provide shell access.

If the last line includes your GitHub username, you have successfully authenticated!

Add New GitHub SSH Remote

Now we can add a new remote to our Git repository using SSH.

First, obtain the SSH address from our repository on GitHub:

Next, use that address to add a new remote origin:

Example

[user@localhost] $

git remote add ssh-origin [email protected]:code7school-test/hello-world.git

Note: You can switch a remote origin from HTTPS to SSH using the command: git remote set-url remote-name [email protected]:username/repository.git.

Example

[user@localhost] $

git remote set-url origin [email protected]:code7school-test/hello-world.git
