SSH

Summary

GitHub offers easy integration with a local SSH client to access public/private repositories via SSH instead of HTTPS.

Instructions

UNIX

Create a personal key:

1. Generate a new SSH key with ssh-keygen -C email@address.com -f ~/.ssh/personal -N "".
2. Copy the output of cat ~/.ssh/personal.pub to GitHub and name it as your machine’s name (eg.: MacBook Pro M2).
3. Append to ~/.ssh/config:

Host personal
	HostName github.com
	PreferredAuthentications publickey
	IdentityFile ~/.ssh/personal

1. Add your identity with ssh-add ~/.ssh/personal.
2. Check if your identity has been added with ssh-add -L.
3. Authenticate with ssh -T git@personal. You should see your GitHub username. Authentication is necessary only once when setting up.

Notes

1. While not necessary, it is generally recommended to keep separate keys for separate machines.
