Configure a custom domain
You can customize your Okta org by replacing the Okta domain name with your own domain name. For detailed information on usage and set up, see Customize domain and email address. 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 domain resets the issuer mode of Identity Providers, Authorization Servers, and OIDC apps to your org's original domain.
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.
