Remote repositories & GitHub — quiz

You've cloned a repo over HTTPS and Git keeps prompting for your username and password every push. What's a more convenient and secure long-term setup?

• Save your password in a plain-text file next to the repo
• Set up SSH key authentication — generate a key with `ssh-keygen`, add the public key to your GitHub account, and use the SSH clone URL. Authentication becomes silent and uses cryptographic keys, not passwords
• Email your password to GitHub support to whitelist your machine
• Disable authentication entirely
