Step 2: Generate SSH Key

1. Run the following command to generate a new SSH key:

   sh

   💡

   Replace sample@mail.com with your own email address associated with your GitHub account.

2. You will be prompted to enter a file in which to save the key. Press Enter to accept the default location.

   

Step 3: Add SSH Key to GitHub

1. Open a web browser and go to GitHub (opens in a new tab).

2. Click on your profile picture in the top-right corner

   

   then select Settings from the dropdown menu.

   

3. In the left sidebar, click on SSH and GPG keys Click on the New SSH key.

   

4. Switch to the Terminal application and run the following command to copy your public SSH key to the clipboard:

   sh

   pbcopy < ~/.ssh/id_ed25519.pub

   OR you can run the following command to print the key to the Terminal and copy it manually:

   sh

   cat ~/.ssh/id_ed25519.pub

   You should see a message like:

   console

   $ cat ~/.ssh/id_ed25519.pub
   > ssh-ed25519 your_key...blablabla your.mail@example.com

5. Return to the browser and paste the copied key into the Key field on the GitHub website.

6. Click the Add SSH key button to save the key.

   

   You have successfully added your SSH key to your GitHub account.

Additional: Test SSH Connection

1. In the Terminal application, run the following command to test the SSH connection with GitHub:

   sh

   ssh -T git@github.com

2. You may see a warning message about the authenticity of the host. Type "yes" to continue.

3. If everything is set up correctly, you should see a message like:

   
   In this case AppleBoiy is my GitHub username. You should see your own username instead.
