Supabase Auth Invalid Redirect URL
Understanding Supabase Auth
Supabase Auth is a powerful authentication tool that provides developers with a seamless way to manage user authentication in their applications. It supports various authentication methods, including email, password, OAuth providers, and more. The primary purpose of Supabase Auth is to simplify the process of integrating secure authentication mechanisms into your application, allowing you to focus on building features rather than handling authentication complexities.
Identifying the Symptom: Invalid Redirect URL
When using Supabase Auth, you might encounter an error message stating "Invalid Redirect URL". This issue typically arises during the authentication process when the application attempts to redirect users to a URL that is not recognized by Supabase.
Exploring the Issue: Why the Error Occurs
The "Invalid Redirect URL" error occurs because the redirect URL specified in your application is not included in the list of allowed URLs configured in your Supabase project settings. Supabase enforces this restriction to prevent unauthorized redirections, which could lead to security vulnerabilities.
Root Cause Analysis
The root cause of this issue is the absence of the redirect URL in the allowed URLs list within the Supabase dashboard. This list acts as a whitelist, ensuring that only specified URLs can be used for redirection after authentication.
Steps to Resolve the Invalid Redirect URL Issue
To resolve this issue, you need to add the redirect URL to the list of allowed URLs in your Supabase project settings. Follow these steps:
Step 1: Access the Supabase Dashboard
Log in to your Supabase account and navigate to the Supabase Dashboard. Select the project where you are encountering the issue.
Step 2: Navigate to Authentication Settings
In the project dashboard, go to the Authentication section. Here, you will find various settings related to user authentication.
Step 3: Update Redirect URLs
Locate the Redirect URLs configuration. Add the URL that you want to use for redirection after authentication. Ensure that the URL is correctly formatted and matches the one used in your application.
Step 4: Save Changes
After adding the URL, make sure to save the changes. This action updates the list of allowed redirect URLs, resolving the "Invalid Redirect URL" error.
