Add a SSH Key to Your Github Account for a Linux Server

Adding an SSH key to your github.com account for a Linux server is easy. I did notice that it appeared I was doing something incorrectly but the issue was actually with Internet Explorer and once I switched to Firefox everything went smoothly.

  1. Open¬†GitHub Account Settings: Open github.com in a browser and login. Click “account” in the top right corner.
    **NOTE** Make sure to use a browser other than IE. Firefox works just fine but IE will not open the area to add a new SSH key.
