AuthKit
Easy to use authentication APIs designed to provide a flexible, secure, and fast integration.
WorkOS AuthKit is a user management platform that provides a set of user authentication and organization security features that securely power your application. Features are designed to be flexible, while offering a fast integration to handle all of the user management complexity that comes with advanced business and customer needs.
AuthKit supports many authentication methods out of the box. They are designed to grow with your app, from the simplest use case all the way to complex Enterprise SSO for your largest customers, these include:
These features are available via AuthKit, or through the public API. AuthKit provides an easy to integrate, pre-built authentication flow, while integrating against the API allows you to implement your own UI and Sign In flow.
The fastest way to integrate AuthKit features is with the Hosted UI.

AuthKit abstracts away many of the UX and WorkOS API calling concerns automatically, allowing you to focus on building your application. See the Quick Start guide for more information on how to get started.
Adopting AuthKit in your app provides a wealth of security benefits.
- Best-in-class email verification, enabled by default.
- Safe identity linking and merging of duplicate accounts. This protects against spoofing and reduces the user support burden.
- Identity Provider (IdP) differences are normalized, so that you get consistency across user profiles. This reduces the likelihood of security issues related to differing semantics across providers.
- Automatic bot detection and blocking, to protect against brute force attacks.
- Multi-Factor Authentication (MFA) available per environment to further enhance your app’s security posture.
