What is Supabase Auth Invalid Credentials

Resolving 'Invalid Credentials' Error in Supabase Auth

Understanding Supabase Auth

Supabase Auth is a powerful authentication tool that provides developers with a simple and secure way to manage user authentication in their applications. It supports various authentication methods, including email/password, OAuth, and third-party providers. Supabase Auth is designed to integrate seamlessly with your existing Supabase database, offering a comprehensive solution for user management.

Identifying the Symptom

When using Supabase Auth, you might encounter an 'Invalid Credentials' error. This error typically occurs when a user attempts to log in with an incorrect email or password. The error message is usually displayed as a notification or alert, indicating that the provided credentials do not match any existing user records.

Common Scenarios

User mistypes their email or password. User attempts to log in with an unregistered email. Password has been changed, and the user is unaware.

Exploring the Issue

The 'Invalid Credentials' error is a common issue that arises when the authentication system cannot verify the user's identity due to incorrect login details. This can be frustrating for users and developers alike, but understanding the root cause can help in resolving the issue efficiently.

Technical Explanation

When a user submits their login credentials, Supabase Auth checks the provided email and password against the stored records in the database. If there is no match, the system returns an 'Invalid Credentials' error. This is a security measure to prevent unauthorized access.

Steps to Fix the Issue

To resolve the 'Invalid Credentials' error, follow these steps:

Step 1: Verify User Input

Ensure that the user has entered the correct email and password. Encourage users to double-check their input for any typos or errors. Implementing a 'show password' feature can help users verify their password input.

Step 2: Check User Registration

Confirm that the user is registered in your Supabase database. You can do this by querying the users table:

SELECT * FROM auth.users WHERE email = 'user@example.com';

If the user is not found, prompt them to register or check for any registration issues.

Step 3: Reset Password

If the user has forgotten their password, provide a password reset option. Supabase Auth supports password reset functionality, which can be implemented using the following command:

auth.api.resetPasswordForEmail('user@example.com');

For more details, refer to the Supabase Auth Documentation.

Step 4: Debugging and Logging

Enable logging to capture authentication attempts and errors. This can help identify patterns or specific issues causing the error. Review the logs for any anomalies or repeated failed attempts.

Conclusion

By following these steps, you can effectively troubleshoot and resolve the 'Invalid Credentials' error in Supabase Auth. Ensuring accurate user input, verifying registration, and providing password reset options are key to maintaining a smooth authentication process.
