It doesn’t have to be that way. Building an MVP with OpenID Connect (OIDC) can be fast, secure, and production‑ready without wasting weeks untangling auth complexity. OIDC is an identity layer built on OAuth 2.0 that makes authentication consistent. When you get it right from the start, you save time, reduce bugs, and avoid security risks.
A Minimum Viable Product needs to ship quickly. That means your authentication can't be a slow burn. Developers often get lost in token exchange, consent screens, provider configurations, and endpoint security. The truth is, most teams overbuild or reinvent. OIDC solves the user login problem in a way that scales from a single prototype to millions of logins—if you cut straight to what matters.
The core idea: let an identity provider handle authentication while your app consumes a verified ID token. Configure your client, send the user through the provider’s authorization endpoint, and handle the callback with the code exchange. That’s it. The rest—token validation, refresh flows, logout endpoints—stays standardized.
