AuthKit
A managed user authentication service from WorkOS that provides hosted interfaces for login, registration, and password reset flows. It supports OAuth integration and multi-factor authentication, enabling web applications to incorporate a complete authentication workflow.

Preview deployment environments also need authentication integrated, and preview domains need to be included in AuthKit's callback addresses and cookie policy, otherwise the problem of 'the preview opens but you cannot log in' will occur.
AuthKit provides a hosted domain by default, but the guide recommends binding the authentication API to your own domain, which makes the cookie's Domain attribute explicit and avoids the cross-origin complexity of relying on a hosted domain.
If the authentication endpoint uses a third-party hosted domain, teams must explicitly add it to CSP directives such as connect-src and frame-src, otherwise requests will be blocked by the browser, and the error message often points to cross-origin rather than CSP.
The guide recommends using an httpOnly cookie to carry the refresh token, with the frontend holding only a short-lived access token, and validating every request on the Node API side.
WorkOS officially published a technical guide, 'Ship a React SPA with AuthKit to production'.
WorkOS AuthKit provides an out-of-the-box identity authentication solution.
Both AuthKit and Better Auth now have built-in SSO, SCIM, and audit logs.
When adopting a managed authentication service (such as AuthKit), the authentication vendor enters the chain of liability as a sub-processor, and enterprises need to list them in the DPA with their end customers and ensure their compliance level is no lower than what the master contract requires.
AuthKit is a managed authentication service, while Better Auth is an authentication solution that leans more toward self-hosting and open source.
Managed solutions are more hassle-free in terms of provider coverage and operational responsibilities, but flexibility and cost are constrained by the vendor, while open solutions grant more control but require taking on more self-building and responsibility.

50%UnverifiedThe hosting party of a hosted authentication solution continuously maintains security updates, compliance requirements, and new authentication methods, but this implies a degree of external dependency, and developers need to weigh convenience against control.
50%UnverifiedSession identifiers are typically written into encrypted cookies with HttpOnly and Secure attributes, preventing JavaScript from reading them directly to improve security.
