Who it's for

Developer and product teams building consumer or B2B SaaS apps who want authentication, identity, and fraud/device-risk checks handled by an API rather than built in-house, from early-stage startups needing passwordless/social login to enterprise-facing B2B products needing SSO, SCIM, and multi-tenant Organizations.

What you get

A hosted authentication API and dashboard covering social login (OAuth), passwordless email/SMS magic links, passkeys/WebAuthn, MFA, SAML/OIDC enterprise SSO, SCIM provisioning, B2B Organizations with RBAC, an Admin Portal, and optional device-fingerprinting/fraud prevention (invisible bot detection, account-takeover protection), plus pre-built frontend UI components and backend/frontend SDKs (including iOS and Android) -- free up to 10,000 monthly active users/agents, 5 SSO or SCIM connections, and 1,000 M2M tokens, then usage-based pricing beyond that.

How it works

Apps integrate Stytch via backend SDKs/API calls (e.g. to test.stytch.com or api.stytch.com) and/or frontend headless or pre-built UI SDKs, with Stytch hosting and operating the authentication infrastructure, user/session/Organization data models, and device-fingerprinting checks -- there is no self-hosted deployment option. Stytch was acquired by Twilio in 2026 and continues to operate as its own product line.
