First, you need to generate an SSH key. Open your terminal or command prompt and execute the following command:

ssh-keygen -t ed25519 -C "[email protected]"

Note: If you already have an SSH key, you can skip this step.

Copy the public key to your clipboard by executing the following command:

• Linux/macOS:

cat ~/.ssh/id_ed25519.pub | pbcopy

• Windows (Git Bash):

cat ~/.ssh/id_ed25519.pub | clip

Access your GitHub account settings and add the SSH key.

• Log in to GitHub, click on your avatar in the top right corner, and select "Settings."
• From the left menu, select "SSH and GPG keys."
• Click the "New SSH key" button.
• Enter a descriptive title and paste the public key from your clipboard into the key field, then click "Add SSH key."

Run the following command to test if the SSH connection to GitHub is working correctly:

ssh -T [email protected]

On the first connection, you will be asked whether to accept the GitHub host key. Type "yes" and press Enter.

If the connection is successful, you should see a message like this:

Hi username! You've successfully authenticated, but GitHub does not provide shell access.

Now you can securely connect to GitHub using SSH when cloning, pushing, and pulling repositories.
