What is Supabase Auth Invalid Email Domain

Understanding Supabase Auth

Supabase Auth is a powerful authentication tool that provides developers with an easy way to implement user authentication in their applications. It supports various authentication methods, including email/password, OAuth, and third-party providers. The primary purpose of Supabase Auth is to ensure secure and efficient user management, allowing developers to focus on building their applications without worrying about the complexities of authentication.

Identifying the Symptom: Invalid Email Domain

When using Supabase Auth, you might encounter an error message indicating an 'Invalid Email Domain'. This error typically occurs during the registration process when a user attempts to sign up with an email address that belongs to a domain not permitted by the application's configuration.

What You Might Observe

Users attempting to register may receive an error message stating that their email domain is not allowed. This can lead to confusion and frustration if not addressed promptly.

Exploring the Issue: Why Does This Happen?

The 'Invalid Email Domain' issue arises when the email domain used for registration is not included in the list of allowed domains configured in your Supabase project. This is a security measure to prevent unauthorized domains from accessing your application.

Understanding Domain Whitelisting

Supabase allows you to specify which email domains are permitted for user registration. This is done through domain whitelisting, a feature that helps maintain control over who can access your application.

Steps to Resolve the Invalid Email Domain Issue

To fix the 'Invalid Email Domain' error, you need to update the domain whitelist in your Supabase project settings. Follow these steps to resolve the issue:

Step 1: Access Supabase Dashboard

Log in to your Supabase Dashboard and navigate to the project where the issue is occurring.

Step 2: Update Domain Whitelist

Go to the 'Authentication' section in the dashboard. Under the 'Settings' tab, locate the 'Domain Whitelist' field. Add the domain you wish to allow for registration. Ensure that you separate multiple domains with commas.

Step 3: Save Changes

After updating the domain whitelist, save the changes. This will immediately update the configuration, allowing users with the specified email domains to register.
