alt Hacker NewsThis is a terrible suggestion. Rolling your own auth nowadays is like rolling your own encryption. It’s just a bad idea. OAuth and OIDC are massive specs that are constantly changing and you’re going to be stuck chasing and developing auth instead of your actual product.
I know because this is what my brain dead principal engineer did and I’ve spent the last 3 years chasing RFCs and am now going to spend the next year migrating to Keycloak because I’ve finally convinced my boss that we’re not an auth company.
I agree you shouldn't write every line by hand, you should use libraries, but pretending like OAuth/ODIC require using something like Cognito/Auto0 is just silly. An LLM can crank out the needed code in very little time and give you full control over your auth instead of fighting an auth provider at every turn.
The number of compromises something like Cognito requires are just not worth the perceived gains.
