The platform offers magic links, one-time passcodes, biometric authentication, OAuth social login, and passkeys through a single unified API, enabling developers to implement any auth flow their product requires. For B2B SaaS products, Stytch provides organization management, SSO, and SCIM provisioning through its B2B Auth product. Stytch differentiates from Auth0 and Firebase Auth through its superior developer experience, extensive customization options, and strong support for passwordless and modern authentication flows that improve conversion rates and security compared to password-based login. The company has built an active developer community and targets companies that want full control over their authentication UI while outsourcing the security infrastructure underneath. Stytch serves companies from early-stage startups to enterprises across consumer applications, B2B SaaS, and marketplace platforms that need reliable, performant authentication infrastructure. ## Frequently Asked Questions ### What is Stytch?
