Instructions for authorizing a domain using DNS TXT as the DCV method

This validation method requires you to create a unique DNS TXT record on your domain's public DNS and add the random value verification token—provided by your Support representative—to the TXT record. When the Support representative does a search for TXT records associated with the domain, we can verify the record's value includes the verification token (random value).

  • eCommerce Note:
    For eCommerce customers (Thawte Certificate Center, GeoTrust Security Center, and RapidSSL Security Center), you can sign in to your account to use the DNS TXT DCV method. You can opt to use the DNS TXT DCV method during certificate enrollment, certificate renewal, or from the Order Status page.

  • CertCentral Note:
    For customers using our CertCentral platform, see our instructions.

  • Management Console Note:
    For customers using the ¶ºÒõ¹Ý Management Console, you can use the DNS TXT DCV method to validate your domains. However, in steps 3 and 4, "_dnsauth.[domain]" is not an option.
