Can I / How can I customize the hosted error page?

The page is only showing our logo and the standard “ooops”. Can I somehow change at least the text?

You certainly can - you can see the below about Custom Error Pages

Alright, so what you are saying is: if I simply want to translate some text on the hosted error page, I need to make that change to a local copy and host it as custom error page on my own server instead. Correct?

Correct - according to the Customized Error Pages section you have two choices:

  • Redirect the user to a custom error page.
  • Configure Auth0 to render a custom error page on your behalf (please note that this feature is only available via the Management API).
