Stytch
Authentication API for passwordless and B2B identity
Stytch is profiled here as a Backend tool for engineering teams. Read about features, pricing, and how it compares to related options in the tools directory.
Description
Stytch is an authentication platform, founded in 2020 by Reed McGinley-Stempel and Julianna Lamb, that gives developers APIs and SDKs for adding login without building it from scratch. It covers passwordless methods such as magic links, one-time passcodes, and passkeys, along with B2B features like organization management and single sign-on for selling to enterprises. Stytch also bundles device fingerprinting and fraud prevention, and it offers a free tier for early-stage projects. The platform ships embeddable UI components alongside a headless API, so a team adopts prebuilt login screens or wires the flows into its own interface.
Key Capabilities:
Passwordless authentication with magic links, one-time passcodes, and passkeys
B2B identity with organizations, single sign-on, and SCIM provisioning
OAuth logins across common social and enterprise providers
