Can someone more intelligent then me tell me why should I offload my postgres users table to some 3rd party provider? Like what is so hard about keeping that table in my VM on hetzner that I have to give it off to someone else? It's not payments, it's just a few fields of data
It’s just a few fields until it’s not. SSO, SAML, SCIM, OIDC, OAuth, 2FA, passwordless auth, verification tokens, etc etc, And, variations of each for wildly popular systems you’ll be expected to integrate with but don’t support the exact spec. For a while at my company, half our support engineers time went to handling random SSO issues that came up in our home built auth system.
All you need is Apple and Google Oauth.
