Authentication platform
FortressAuth
Authentication with a clear foundation.
A TypeScript authentication platform with an independent core, database adapters, OAuth providers and client SDKs.

The problem
Why we built it.
Sign-in is only one part of authentication. Developers also need session handling, recovery flows, provider integrations and an architecture they can adapt to their stack.
What the application does.
- Password, session, email-verification and password-reset flows, plus OAuth provider integrations.
- SQL and MongoDB adapters, with a core that stays separate from infrastructure.
- Client SDKs, a standalone HTTP server, API documentation and example integrations.
Engineering evidence
Beyond the interface.
- TypeScript
- Node.js
- SQL
- MongoDB
- Pulumi
A ports-and-adapters architecture keeps domain logic separate from storage and transport.
Security-focused implementation includes Argon2id hashing, token-verifier hashing, rate limiting and CSRF protection.
The repository includes framework SDKs and infrastructure automation alongside the authentication engine.
Take a closer look.
The public website, documentation and source code provide a closer look at the platform. These implementation details are not a claim of independent security certification.
