Default Auth0 Error Page

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.


The generic error page displays the following information if you have configured the associated fields in your Tenant Settings.

Field Description
Friendly Name Name of your company
Logo URL URL of your company logo
Support Email Email address of your company's support team

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

connection Connection used at the time of error.
lang Language set for use at the time of error.
