What's the best LoginWith "provider" if you don't want it to be Google/Gmail or another "commercial"/"silo" vendor?
(In 2021, Twitter might have been the answer.)
Github? Not enough non-devs will do it. (And does it still count as non-commercial since MS bought it?)
WordPress?
Or maybe you offer Github, plus classic email/password as fallback?
I'm especially thinking of a pattern for #ToolsForThought to follow....
