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.
    After the domain is validated, you can add the canonical name to the CNAME record for your custom domain. The CNAME record points your custom domain name, such as auth.example.com, to the canonical name provided by PingOne.
