Response from Martin Woodward, GitHub’s VP of Developer Relations:

Sorry for the inconvenience @koepnick - while searching across all repos has required being logged in for a long time, when we enhanced the search capabilities earlier in the 2023 we had to extend this to repos as well (see https://github.blog/changelog/2023-06-07-code-search-now-requires-login/).

This is primarily to ensure we can support the load for developers on GitHub and help protect the servers from being overwhelmed by anonymous requests from bots etc.

  • Anyone without access to their old email also loses their account. I don’t remember which email address I used with my account back in the day (it’s at least ten years old), and since I bought my key from a reseller, I don’t have a receipt. Microsofts response was basically “not our problem, guess you’ll have to pay us again ¯\_(ツ)_/¯”
