in a few hours and as announced since february (
https://developer.github.com/changes/2020-02-14-deprecating-password-auth/ ), Github will deprecate some APIs. We have updated jenkins and plugin
hoping this is handled by upstream (cause we can't test, we do not
control github ), but we still have 1 tool somewhere that do from to
time trigger a github alert (like once every month). Given the sporadic
nature of the alert, we didn't managed to find what caused that.
