TIL how to set up multiple SSH keys (for multiple Github accounts)

Fri, 28 Nov 2025 16:20:00 +0000

Setting up SSH keys is one of these things I need to do every couple of months. Inevitably, I don’t remember how to do it and then follow some tutorial, e.g. the Github Docs . It kind of always works but I haven’t fully internalized how to properly manage those different SSH keys.

Disclaimer: This learning was provoked by setting up multiple SSH keys for different Github accounts (I know how to do that) and then being able to git clone {private-repository} a private repository with the correct ssh key (I didn’t know how to do that). An example use case could be a personal and professional Github account that don’t have access to the same private repositories. So ideally when we git clone we want to automatically pick the right ssh key.

Interesting discussion of git config options that the git core developers favor and that are not (yet) defaults. There are some nice suggestions. For example, I didn’t know that

git config --global push.autoSetupRemote true

existed. If you haven’t defined an upstream for a branch yet, git will automatically set it for you. So you don’t have to run

git push --set-upstream origin my-branch-name

anymore.

Some other options I adopted from this post:
