1. Go to Settings > Domains.
  2. Click + Add custom domain.
  3. Enter the domain name, such as auth.example.com and click Save. PingOne validates the domain name to ensure that it is not already in use.

    Before the custom domain becomes active, PingOne requires that you provide an appropriate SSL certificate and point your custom domain to a PingOne-supplied canonical name using a CNAME record. The CNAME record proves that your custom domain is not already in use and directs requests to your custom domain through your PingOne environment.
