Configure a custom URL domain
You can customize your Okta org by replacing the Okta domain name with your own URL domain name. For detailed information on usage and set up, see Customize the Okta URL Domain. If you can't find what you're looking for, contact Okta Support.
Be sure to share the URL exactly as you customized it. Redirect URLs do not work.
Disabling a custom URL domain resets the issuer mode of Identity Providers, Authorization Servers, and OIDC apps to your org's original URL.
Custom domains with Okta-managed certificates
Okta-managed certificates automatically renew through a free certificate authority called Let’s Encrypt. Allowing Okta to handle certificate renewals reduces your customer developer maintenance costs and eliminates the risk of a site outage when certificates expire.
