Three Ways to Git Clone with a Different SSH Key

The article explains how a GitHub clone can fail when Git uses the wrong SSH key for a private repo.

It shows three ways to use the correct identity: a one-time GIT_SSH_COMMAND override, a repo-level core.sshCommand setting, and an SSH Host alias.

For wider reuse, it also demonstrates pairing an SSH config alias with a url.insteadOf rewrite.

These techniques help avoid misleading access errors when working across multiple GitHub accounts or orgs.
