Stytch

Stytch is a modern, developer-centric identity platform designed to fundamentally simplify authentication and authorization for web and mobile applications. It addresses the security vulnerabilities and poor user experience of traditional authentication methods by providing a flexible, secure, and scalable solution. Stytch is uniquely positioned to handle identity for both human users and emerging AI agents, making it a future-proof choice for any modern application. The platform offers a comprehensive toolkit, from embeddable login UIs and headless SDKs to powerful backend APIs, allowing development teams to offload as much or as little of the authentication stack as they need, accelerating their time-to-market while enhancing security.

How to use Stytch

Integrating Stytch is a straightforward process designed for developers:

1. Sign Up and Get Keys: Start by creating a free account on the Stytch platform to access your project's API keys.
2. Choose Your Integration Method: Select the best fit for your stack. You can use pre-built, customizable frontend components for frameworks like React and Next.js, leverage headless SDKs for iOS, Android, and web for full UI control, or interact directly with the powerful backend APIs.
3. Configure Authentication Methods: Implement your desired login flows. Stytch supports a wide array including modern Passkeys, Email Magic Links, OAuth with providers like Google and Microsoft, enterprise-grade SSO (SAML & OIDC), and breach-resistant passwords.
4. Implement B2B Multi-Tenancy: For SaaS applications, utilize Stytch's native multi-tenant data model, built around Organizations and Members. Configure per-organization settings like required MFA, set up Just-in-Time (JIT) provisioning, and manage roles with RBAC.
5. Secure Your Application: Enable advanced security features with a single click. Use Device Fingerprinting for industry-leading bot detection, apply intelligent rate limiting, and enforce MFA to protect against account takeover (ATO) and other sophisticated threats.
6. Manage AI Agent Identity: For AI-powered products, use Stytch's Machine-to-Client Protocol (MCP) server authentication to securely connect AI agents to user data and services, managing permissions and user consent seamlessly.
