Authentication is a solved problem…
So, why is it so hard to build?
Build Authentication Like You Build Everything Else: In Code.
Prefactor empowers developers with a purpose-built domain-specific language (DSL) and CLI that transforms how you build authentication.


Adaptive Authentication for Modern Teams
SSO, MFA, Magic Links, Passkeys and Social Logins — dynamically managed by intelligent systems that learn, update, and optimize as your security and user needs grow.
Manage Auth Like Infrastructure: Versioned, Tested and Deployed
Version-controlled, testable, and deployable through your CI/CD pipeline. Prefactor gives you a unified layer to define access once and ship it everywhere.


Reduce risk, improve security
Enhance security with AI-powered dynamic behaviour management, providing real-time auditing, anomaly detection, and swift response to potential threats.
Why does building the user layer feel so broken?
Limited customization
Current tools promise simplicity but box you into rigid flows that can't be adapted to your needs.
Growing complexity
Manual configuration
Managing change from development into production using web-based configuration is inefficient and error-prone.
No unified view
You can’t see in one place how authentication and authorization are specified, making auditing and compliance a nightmare.
Build with code, not compromises
Low Code Tools vs. Prefactor
Low-code system
Simple but inflexible. A quick fix today, a bottleneck tomorrow.
VS
Prefactor
A DSL crafted for developers to define authentication flows, policies, and permissions with precision and growth in mind.
Why a DSL?
Code is clarity
Prefactor’s DSL integrates directly into your workflow, giving you control over your app’s logic.
Test what you build
Preview and stage every update before it goes live.
Version everything
Track changes, rollback with ease, and maintain a full audit trail.
The result?
You build smarter, faster, and without compromise
Delivering precision, transparency, and control
Choose a platform which authenticates, authorizes and audits your users with the flexibility of writing code yourself but with the benefits of a hosted platform
