GitHub asks for username with SSH configured
If you use GitHub in any capacity, you should be using a public key with your account. It’s one of those blissfully–rare occurrences where security and convenience intersect. GitHub recommends using HTTPS URLs, but I still reckon SSH is easier.
Despite configuring it, pushing commits to a newly-cloned repo resulted in a password prompt. This means the SSH key isn’t being used.
$ git push origin master Username for 'https://github.com': ^C
This was a new machine reload, and my orchestration scripts had configured Git in the past without any problems. Well, with as few as possible problems as one could expect from Git.
Lesson learned, don’t tackle Git before your morning coffee.
