Secure Shell (SSH) authentication is the recommended way to securely connect to GitHub repositories without needing to enter your credentials every time.
To configure SSH authentication for GitHub, follow these steps:
1. Check for existing SSH keys by running 'ls -al ~/.ssh'.
2. Generate a new SSH key using 'ssh-keygen' command.
3. Add your SSH key to the SSH agent.
4. Add the SSH key to your GitHub account.
You can also test the SSH connection and configure Git to use SSH.
By following these steps, you can securely connect to your GitHub repositories using SSH authentication.
