You know, I really don't wanna bother with OAuth right now.
But also I don't wanna tell my potential users (all 3 of them) "hey, I migrated to a different auth, all your passwords are now reset" mostly for the sake of adding Google login sometimes.
Why OAuth so heckin hard.
Screw that. I'm not gonna let some birdsite influencer push me into overcomplicating my project.
For an MVP, I think, simple password-based auth is fine.
I would want fancier stuff later, and I can just use an OAuth2 library to add other auth providers.
For now at least, I do not foresee a need to bother with a centralized SAAS solution.
