For multiple git accounts on a single machine simply set the remote path that includes the username using https rather than ssh. that is:
git remote set-url origin https://USERNAME@github.com/USERNAME/PROJECTNAME.git
and you are good to go:
git push
When you first enter your password, you will probably see this message:
Support for password authentication was removed on August 13, 2021.
You must use a Github PAT to do HTTPS pushes on github.com
Your PAT will look like a 40 character letter/number hash, like
zIa03uTnN0TTaReAALT09K33NMBbCfum6lw8TDSb
When you push using this method, you will be presented with a dialog box when you push:
To ensure that the commits appear as performed by USERNAME, one can setup the user.name and user.email for this project, too:
git config user.name USERNAME
git config user.email USERNAME@example.com
