When it comes to building modern applications, user authentication is one of the most critical components. Ensuring that your app is secure, user-friendly, and scalable can be a complicated, time-consuming task. Auth0 is a popular choice for handling authentication, but what if you're looking for an open-source alternative?

Appwrite’s Authentication feature provides such open-source alternative to Auth0. In this article, we’ll give a detailed comparison of Appwrite and Auth0 features so you can understand how each provider will fit your specific needs.
