Teneo Auth Platform
Enterprise authentication with a shared integration process. Zero prior backend experience.
A shared authentication architecture
The design separates identity, application access and integration checks. Each application still needs its own configuration, testing and verified deployment. This walkthrough explains the approach; it does not establish a standard integration time.
The Problem
Building multiple AI apps (Teneo, BookCoverGenerator, ProfileEngine, etc.). Each needed authentication. Each needed user management. Each needed security.
The Traditional Approach Would Be:
- • Build auth for each app separately (weeks per app)
- • Duplicate user tables across databases
- • Manage separate login flows
- • Handle password resets independently
- • No single sign-on across services
That's insane. I needed centralized authentication that just works.
The Solution
Built Teneo Auth: A centralized authentication platform that serves all Teneo services with a repeatable integration process. Each application still needs configuration and verification.
Technical Architecture
- Next.js API routes: Serverless authentication endpoints that scale automatically
- Supabase backend: PostgreSQL + Auth + Row Level Security. Enterprise-grade without enterprise complexity
- Domain-based login: One central auth.teneo.io that serves all services. No duplicate code.
- Session management: JWT tokens, secure cookies, automatic refresh. Just works.
- Multi-tenant ready: Each service can have custom branding, email templates, redirect flows
How Integration Actually Works
Step 1 (5 min): Register the new service in auth.teneo.io config. Add domain, redirect URLs, branding.
Step 2 (10 min): Add auth middleware to the app. Copy-paste from template. Works immediately.
Step 3 (5 min): Test login flow, password reset, session management. Done.
These are the integration steps. Production readiness also requires access-control, recovery and deployment checks for the application.
Services Using Teneo Auth
teneo.io
Main book generation platform. User accounts, partner management, payment integration.
bookcovergenerator.ai
AI design platform. User accounts, design history, saved templates.
ProfileEngine
Psychological profiling. User accounts, assessment history, results storage.
traviseric.com
Personal site. Course access, admin panel, content management.
conversos
Conversation orchestration. User accounts, conversation history.
+ More Apps
10+ apps at various stages. All will use Teneo Auth when they ship.
What I Learned
Build infrastructure early, not per-app
I almost built auth separately for each app. Would have wasted weeks. Instead: Build shared infrastructure once, reuse forever. Now integrating a new app starts from shared integration code rather than a separate authentication implementation.
Zero backend experience isn't a blocker anymore
6 months ago I didn't know what PostgreSQL was. Today I'm running enterprise auth for multiple production apps. AI as co-architect + willingness to ship imperfect V1s = you can build anything.
Multi-tenant architecture pays dividends
Each service gets custom branding, email templates, redirect flows. One central codebase, infinite flexibility. Users don't know they're using the same auth system across different apps. That's the point.
Real Impact
Time saved: Would have spent Repeating authentication work for each application. Shared components reduce duplication; setup and verification time vary.
Security: One codebase to secure, not 6+. Updates reach a service when its integration and deployment are updated and verified.
User experience: Single sign-on across all Teneo services. Users log in once, access everything.
Scalability: Can integrate unlimited new services. Infrastructure scales with ambition.
