+### Use Custom Redirect URLs
 
+Instead of relying on the default `{{ .ConfirmationURL }}` path, you could optionally configure a **custom redirect URL** in Supabase. This option allows you to bypass the default setup and send users directly to a custom page in your app for resetting their password.
+
+To configure a custom redirect URL:
+
+1. When adding the **Send Reset Password Email** action in FlutterFlow, enter the **Redirect To** URL. For example `http://my-site.com/resetPassword`.
+2. Whitelist this custom URL by navigating to **Supabase Dashboard > Authentication > URL Configuration > Redirect URL**, and click **Add URL** to include it.
+3. Update the reset password template. Go to **Supabase Dashboard > Authentication > Email Templates > Reset Password > Source** and ensure only `{{ .ConfirmationURL }}` is present in the template (remove any appended route names).
