Below is a brief list of steps to perform to create and use SSH keys in Git Bash and Visual Studio Code or Community.
Generate the SSH key
Open Git Bash and run:
ssh-keygen -t rsa -b 4096 -C "<email>" ssh-add ~/.ssh/id_rsa
The latter command failed in my case
Add the key to GitHub
Follow the instructions from https://help.github.com/en/articles/adding-a-new-ssh-key-to-your-github-account.
Check the repository’s remote
Make sure you use the git protocol in your repository. Either edit the
.git/config folder or run the command
git branch -v.
[remote "origin"] url = https://github.com/<username>/<repo>.git
[remote "origin"] url = firstname.lastname@example.org:<username>/<repo>.git
