Set up GitHub push with SSH keys

Set up GitHub push with SSH keys.md

SSH keypair setup for GitHub (or GitHub/GitLab/BitBucket, etc, etc)

Create a repo.

Make sure there is at least one file in it (even just the README.md)

Generate a SSH key pair (private/public):

ssh-keygen -t rsa -C "your_email@example.com"

or even better:

ssh-keygen -t rsa -b 4096 -C "your_email@example.com"

Copy the contents of the public SSH key

macOS:

pbcopy < ~/.ssh/id_rsa.pub

GNU/Linux (requires the xclip package):

xclip -sel clip < ~/.ssh/id_rsa.pub

Windows Command Line:

type %userprofile%\.ssh\id_rsa.pub | clip

Git Bash on Windows / Windows PowerShell:

cat ~/.ssh/id_rsa.pub | clip

or ofcourse copy it via your favorite editor, cat, or whatever suits your needs :)

Copy the public SSH key to GitHub

Copy the contents of the to your SSH keys to your GitHub account settings (https://github.com/settings/keys).

Test the SSH key:

ssh -T git@github.com

Change directory into the local clone of your repository (if you're not already there) and run:

git remote set-url origin git@github.com:username/your-repository.git

Now try editing a file (try the README) and then do:

git add -A
git commit -am "Update README.md"
git push

You should not be asked for a username or password. If it works, your SSH key is correctly configured.
