In addition to customizing your URL domain and hosted sign-in page, you can customize the default Okta error page so that it is also consistent with your application. The Custom Error Pages tab of the Customization page provides an embedded HTML editor to help you get started. For detailed information on usage and set up, see the Customize the Hosted Error Pages guide.
Note: Additional customization options are available with Branding. This is an Early Access feature. To enable it, use the Early Access Feature Manager as described in Manage Early Access and Beta features.
