Change a domain's domain control validation (DCV) method

In your account, in the sidebar menu, click Certificates > Domains.

On the Domains page, use the drop-down lists, search box, and column headers to filter the list of domains.

In the Domain Name column, click the link for the domain you need to change the DCV method for.

On the domain information page, in the User Actions section, click Change DCV Method.

In the Change DCV Method window, under Domain Control Validation (DCV) Method, select the DCV method you want to use to complete the validation for the domain.
If you change the DCV method for a domain that is pending validation, you will void any pending verification emails or unique verification tokens.

• Verification Email
  To demonstrate control over the domain, an email recipient follows the instructions in a confirmation email sent for the domain.
• DNS CNAME Record
  To demonstrate control over the domain, you add a DigiCert generated token (provided for the domain in your CertCentral account) to the domain’s DNS as a CNAME record.
• HTTP Practical Demonstration
  To demonstrate control over the domain, you host a file containing a DigiCert generated token (provided for the domain in your CertCentral account) at a predetermined location on your website ([domain]/.well-know/pki-validation/[filename].txt).
• DNS TXT Record
  To demonstrate control over the domain, you add a DigiCert generated token (provided for the domain in your CertCentral account) to the domain’s DNS as a TXT record.

When you are finished, click Change DCV Method.
