Configure a custom URL domain
You can customize your Okta org by replacing the Okta domain name with your own URL domain name. With your branding on all URLs, you can create a seamless experience for your users. For example, if the URL of your Okta org is https://example.okta.com, you can configure a custom URL for the org such as https://id.example.com.
Disabling a custom URL domain resets the issuer mode of Identity Providers, Authorization Servers, and OIDC apps to your org's original URL.
