Copy the SSH Public Key

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

Now we will use the clip < command to copy the public key to our clipboard:

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

Go to GitHub, navigate to the top left corner, click your profile, and select: Settings:

Then select "SSH and GPG keys". and click the "New SSH key" button:

Select a title, and paste the public SSH key into the "Key" field, and click "Add SSH Key":

You will be prompted to supply your GitHub password.

You will see your new SSH key added:

Test SSH Connection to GitHub

Now we can test our connection via SSH to GitHub:

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 w3schools-test! You've successfully authenticated, but GitHub does not provide shell access.

If the last line contains your username on GitHub, you are successfully authenticated!

Add New GitHub SSH Remote

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

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

Then use that address to add a new origin:

git remote add ssh-origin [email protected]:w3schools-test/hello-world.git

git remote set-url origin [email protected]:w3schools-test/hello-world.git
