Authentication is the first thing users interact with. It needs to work perfectly.
Clerk is the authentication platform for modern Next.js applications. Social login, magic links, multi-factor authentication, organization management, and the middleware that protects routes — implemented correctly, with the user experience that makes signup frictionless.
Next.js application with broken, incomplete, or homegrown authentication — that needs social login, proper session management, and route protection that actually works
Authentication is one of the most security-critical parts of any application, and one of the most commonly done poorly. The failure modes:
Homegrown JWT auth. Custom JWT implementations without proper signature verification, without refresh token rotation, without session invalidation on logout, and without the security updates that production auth requires. Home-built auth is a security liability.
Missing route protection. Authentication without middleware-level route protection means that any user who knows the URL can access protected pages by navigating directly. clerk/nextjs middleware configured on the wrong paths, or not configured at all.
No organization support. B2B SaaS applications need organizations (workspaces, teams) — one account that can belong to multiple organizations, with org-scoped data access. Building organization management from scratch is weeks of work. Clerk has it built in.
Missing MFA. Enterprise customers require multi-factor authentication. Clerk supports TOTP authenticator apps and SMS MFA. Not enabling it costs enterprise deals.
SSO for enterprise. Enterprise accounts want to log in via their company's SSO provider (Okta, Azure AD, Google Workspace). Clerk's Enterprise SSO (SAML/OIDC) enables this without custom implementation.
Complete Clerk authentication implementation: social login, magic links, MFA, middleware-based route protection, and user management UI
Social login
Google, GitHub, LinkedIn, and other OAuth providers configured in Clerk. Seamless one-click authentication with automatic account creation.
Magic links and OTP
Passwordless authentication via email magic link or SMS OTP. Configured with Clerk's email template customization.
Middleware route protection
`clerkMiddleware` configured in `middleware.ts`. Public routes defined explicitly. Protected routes requiring auth redirected to sign-in.
Organization support
Org creation and invitation flow. Org membership and role management. Org-scoped data access via `auth().orgId` in server components.
MFA and SSO
TOTP multi-factor authentication configured. Enterprise SSO (SAML) configured for enterprise customers. SSO connection management via Clerk dashboard.
One honest number to start.
Fixed-scope, fixed-price. The number below is the starting point — final scope is built from your brief.

Three steps, every time.
The same repeatable engagement on every project. No surprises, no mystery, no billable ambiguity.
Brief & discovery.
We send you questions, then get on a call. Output: a written scope with every step, feature, and integration listed.
Build & ship.
Fixed schedule, weekly reviews. No scope creep unless you change the scope — and if you do, we reprice it transparently.
Warranty & retainer.
30-day warranty on every launch. Most clients stay on a monthly retainer for ongoing features and maintenance.
Why Fixed-Price Matters Here
Auth implementation scope is defined by the authentication methods, the org structure, and the SSO requirements. Fixed price.
Questions, answered.
Don't build your own auth. Clerk handles the security complexity — session management, token rotation, breach detection, MFA, SSO — that a custom implementation would need to rebuild and maintain. The monthly cost of Clerk ($25/month for most applications) is less than the engineering cost of maintaining a custom auth system.
Clerk's Next.js SDK supports React Server Components. `auth()` (for server components) and `useAuth()` (for client components) are the primary auth primitives. Middleware runs on every request and is configured in `middleware.ts`.
Auth is included in the application build. Full application from $25k. Fixed-price.
