Simple login is not working

Help
1

Hello everyone, I am fighting with a generated code that doesnt’ work. Could you please help me?

What I would like to do: Create a login module to access a secure content.

What happens: After creating the database and the login form, and after input the right credentials, it redirects to login page again and again.

Any clue?: As the logs says, the cookies are not being saved.

Step by step:

  1. Create a blank project
  2. Create a prompt like “Create a dashboard page that shows after login”
  3. It creates the dashboard and login, and ask you to create the database and scripts. Everything runs perfectly.
  4. I need to create the user, and profile, and also remove teh “validate email” option from Supabase settings.
  5. After everything is done, I input right credentials and instead of redirecting to Dashboard, it redirects to Login agin.

It is driving me crazy.

Thank you

This sounds like a cookie/session management issue with your authentication flow. Here are a few things to check:

1. Supabase Configuration

  • Make sure your Supabase URL and anon key are correctly set in your environment variables
  • Verify that Row Level Security (RLS) policies are properly configured for your user table
  • Check that email confirmation is disabled in Supabase Auth settings if you’re not using it

2. Cookie Settings

  • Ensure your authentication cookies are being set with the correct domain and path
  • Check if you’re running on localhost vs a custom domain - this can affect cookie behavior
  • Verify that httpOnly and secure flags are appropriate for your environment

3. Middleware Configuration

  • Make sure your middleware is properly checking for authentication state
  • Verify that protected routes are correctly configured
  • Check that the middleware isn’t interfering with the login flow

4. Session Persistence

  • Confirm that the session is being properly stored after successful login
  • Check browser developer tools to see if cookies are actually being set
  • Verify that the session validation logic is working correctly

Let us know how you get on!
