You can connect any application (written in any language or on any stack) to Auth0 and define its Connection, the method used to authenticate the users of that application:



Clerk is more than a "sign-in box." Integrate complete user management UIs and APIs, purpose-built for React, Next.js, and the Modern Web.

FusionAuth is an auth for any app. Get everything you need for secure registration and user management in minutes. Single-tenant, on-prem or private cloud, custom emails with localization, social login, and more.




Frontegg is a developer platform that enables product-led-growth through a customer-facing user-management interface embedded seamlessly within any product.
