1GitHub Authentication (HTTPS & SSH) — What You'll Learn
Authenticate securely with GitHub using either HTTPS with personal access tokens, or SSH keys.
Here's everything this chapter covers, in the order you'll learn it:
- HTTPS-based authentication
- Personal access tokens (replacing passwords for HTTPS)
- SSH-based authentication
- Generating a new SSH key pair
- Adding your public SSH key to GitHub
- Testing your SSH connection
- Switching a repository's remote URL between HTTPS and SSH
- How the credential manager stores saved logins
- Scoping token permissions correctly
- Rotating tokens periodically for security
2Working Example
💻 Example: GitHub Authentication (HTTPS & SSH)
Bash
ssh-keygen -t ed25519 -C "you@example.com"
ssh -T git@github.com3Best Practices & Common Pitfalls
💡 Key things to remember:
- SSH keys are generally more convenient for frequent pushing (no repeated token prompts) and are considered the more secure long-term option for personal machines.
