Before you generate an SSH key, you can check to see if you have any existing SSH keys.
Open the command line and enter:
ls -al ~/.ssh # Lists the files in your .ssh directory, if they exist
- Check the directory listing to see if you already have a public SSH key.
If you don't have an existing public and private key pair, or don't wish to use any that are available to connect to GitHub, then generate a new SSH key.
Tip: If you receive an error that ~/.ssh doesn't exist, don't worry! We'll create it when we generate a new SSH key.
