Tech Stack & Architecture
What’s the best authentication setup for a SaaS MVP (OAuth, SSO, magic links)?
Answer:
For most SaaS MVPs, use a proven authentication provider (Auth0, Clerk, Firebase Auth, Cognito) or a mature library. Support email/password or magic links first, then add Google/Microsoft OAuth if customers request it. Enterprise SSO (SAML/SCIM) is powerful for sales, but usually comes later unless you target B2B from the start.
