How to link git to your github account in a new Mac OS

Generate new ssh key for my github email without passphrase:

ssh-keygen -t ed25519 -C "my@email.com"
eval "$(ssh-agent -s)"
echo -e "Host github.com\n  HostName github.com\n  IdentityFile ~/.ssh/id_ed25519\n  IdentitiesOnly yes" >> ~/.ssh/config
ssh-add -K ~/.ssh/id_ed25519

Add it to my github keys:

gh ssh-key add ~/.ssh/id_ed25519.pub

Verify GitHub is authenticated (otherwise troubleshoot here):

ssh -T git@github.com
# Hi __username__! You've successfully authenticated, but GitHub does not provide shell access.
