The Auth0 extension for Netlify aims to simplify authentication by connecting Auth0's capabilities with Netlify apps. This move reflects Netlify's commitment to extensibility and its goal of creating a modular, composable platform where developers can use the best tools for their specific needs. The introduction of the Auth0 extension follows the recent announcement of Netlify Extensions, which has already seen tens of thousands of developers add extensions and several Enterprise customers integrate multiple extensions across their organizations. With this shift, Netlify Identity is being deprecated, but existing users can continue using it as-is or migrate to Auth0. The company plans to focus on helping with migrations and providing support for new projects, where the Auth0 extension will be recommended alongside other authentication solutions.
