SaaS Starter Pro

Auth system (PRO)

Production-ready authentication with real flows, OAuth, security, and account lifecycle.

Authentication that actually works

Starter PRO

Starter Free gives you auth UX and flows. Starter PRO gives you real authentication wiring and security foundations.

This is not just login.

This is the full authentication lifecycle of a real SaaS.


What this includes

The PRO auth system is a production-ready authentication layer.

You get:

  • Email + password authentication
  • Google OAuth
  • GitHub OAuth
  • Email verification flow
  • Forgot / reset password
  • In-session password change
  • Add password for OAuth users
  • Connected accounts management
  • Safe provider disconnect
  • Security activity tracking
  • Rate limiting (database-backed)

Everything is already structured, integrated, and ready to use.


Real flows (not placeholders)

This is not UI simulation.

You already have:

Sign in

  • Credentials
  • OAuth providers
  • Error handling (invalid credentials, provider mismatch)

Register

  • Account creation
  • Password validation
  • OAuth instant signup
  • Email verification step

Password reset

  • Secure token system
  • Reset flow
  • Expiration handling

Account security

  • Connected providers
  • Safe unlink logic
  • Security activity logs

What changes vs Starter Free

Starter Free gives you:

  • Auth screens
  • UX states
  • Navigation
  • Mock flows

PRO adds:

  • Real sessions (Auth.js)
  • Database integration (Prisma)
  • Token lifecycle (verification / reset)
  • OAuth provider wiring
  • Security protections
  • Rate limiting

Why this matters

Authentication is not just login.

It is:

  • your first security layer
  • your first user experience
  • your first production risk

Most starters stop at UI.

You still have to build:

  • token systems
  • provider linking
  • edge cases
  • security rules

This typically takes several days or weeks.


What you avoid building

Without PRO, you would need to implement:

  • password hashing & validation
  • token lifecycle (verify / reset)
  • OAuth linking logic
  • account edge cases
  • safe provider disconnect
  • rate limiting

PRO removes this entire layer.


Mental model

Starter Free → simulate auth Starter PRO → handle real users


How it integrates

No rewrite required.

You keep:

  • pages
  • layouts
  • components
  • UI structure

You replace:

  • mock auth → real sessions
  • fake states → real data

When you need this

Upgrade when:

  • users need to sign in for real
  • you onboard real users
  • you prepare monetization
  • you need production security

The payoff

Instead of building auth:

  • you configure providers
  • you plug environment variables
  • you ship

Authentication is one part of the system.
