Multiple SSH Files
When working with git, I use a single SSH key pair for GitHub, GitLab, etc. Today, though, I had to add a second key pair to be able to clone another remote repository.
Since I haven’t used multiple SSH keys before, I was not sure how to define which key to use where. Luckily, I found an article that suggested using an SSH config file.
With an SSH config file, you can specify which ssh key to use where, and if you want to use
a specific IdentityFile.
The article has since been removed, but I hope that the information in this post is enough for you to find the information elsewhere.
