Authentication and authorization in TypeScript applications can be handled via a framework-agnostic solution using a plugin architecture. This approach manages user sessions, multi-factor authentication, and passkeys without locking you into a specific backend framework.

Yes, multi-factor authentication and passkeys can be added to TypeScript backends through dedicated plugins. The system requires registering the necessary plugins on both the server and client-side to enable full multi-factor and passkey functionality.

Yes, the authentication and authorization solution is framework-agnostic, meaning it works with any TypeScript backend. It handles user management and session control independently of your chosen web framework through its plugin architecture.

Setting up multi-tenancy and SSO for TypeScript SaaS applications is best handled through an authentication solution with dedicated plugins. You register the multi-tenancy and SSO plugins on both server and client sides to manage team-based access control.

API keys for third-party integrations can be generated using an authentication system's API Key Management plugin. You must register the plugin on your server and client to securely handle API key generation and third-party access.

Framework-agnostic auth solutions require server and client-side plugin registration to ensure full functionality across the entire stack. This dual registration synchronizes user management and session control mechanisms between your backend and frontend.
