Default Auth0 Error Page

Describes the default Auth0 error page display information and parameters used for authorization error events.

If your callback URL is valid, when an authorization error occurs, the Authorization Server returns the appropriate error and state parameters to your callback URL. In cases where your callback URL is invalid, your application will display the default generic Auth0 error page. Alternatively, you can customize the error pages. To learn more, read Custom Error Pages.

To find the default page name for the generic error page, see Use Version Control to Manage Your Universal Login Pages.

Field	Description
Friendly Name	Name of your company
Logo URL	URL of your company logo

Parameters

The Authorization Server returns parameters appended to the URL as a query string.
