Meet Stytch

Stytch provides APIs, SDKs, and interface components for adding authentication and authorization to an application. Developers can build sign-in flows around passkeys, passwords, or enterprise single sign-on, then configure policies for individual customer organizations. An embeddable admin portal lets those customers manage authentication settings and organization membership within the application's own dashboard.

The platform also handles machine-to-machine authentication and connected applications, including access and consent for AI agents. Device signals, rate limits, and multifactor authentication provide controls for investigating and responding to suspicious activity. You can use supplied login components or build a custom interface around the underlying APIs.
