How does extensibility help with custom migrations?

Auth0’s extensibility is a core advantage for custom user migrations. Using 'Custom Database' scripts, you can more securely migrate users from a legacy system to Auth0 in real-time, without requiring them to reset their passwords. This 'trickle migration' helps ensure a seamless transition for the user while allowing you to modernize your identity infrastructure at your own pace.

What is the Auth0 Marketplace?

The Auth0 Marketplace is a hub for pre-built integrations and serverless functions created by Auth0 and its partners. It allows developers to quickly add sophisticated features—like identity verification, MFA, and consent management—to their login flow with minimal coding. This speeds up development and helps ensure that customizations follow industry best practices for security.

What is the difference between Auth0 Actions and Rules?

Auth0 Actions are the modern, serverless evolution of legacy Rules. While Rules were simple JavaScript functions, Actions offer a more robust developer experience with an integrated IDE, version control, and support for the full Node.js ecosystem. Actions are more performant and easier to maintain, making them the recommended way to extend the Auth0 platform.

What makes the Auth0 platform extensible?

The Auth0 platform is highly extensible so customers can customize and set up authentication specific to their unique business requirements. Auth0’s Extensibility provides pro-code to no-code capabilities including Actions, Forms, Event Streams, and Auth0 Marketplace. Actions helps customers build the authentication pipeline and Identity flows using code for use cases like Access Control, API Authorization and more… Forms provides a visual editor for customer identity orchestration, and helps customers build and personalize signup and login flows with no-code editor, used for use cases like custom signup steps, account linking and progressive profiling. Event Streams enables developers to subscribe to completed changes and route those events to a destination of your choice using Webhooks, Amazon EventBridge, or Auth0 Actions, in order to keep data in sync across internal and external systems and trigger business workflows in downstream applications. And Auth0 Marketplace has pre-built partner integrations for customers to leverage no-code templates and integrations for third party integrations.
