Update DNS records

At your authoritative DNS provider, create a TXT record named the txt_name and containing the txt_value.

Repeat this process for all the DCV records returned in the validation_records field to your Authoritative DNS provider.

If one or more of the hostnames on the certificate fail to validate, the certificate will not be issued or renewed.

This means that a wildcard certificate covering example.com and *.example.com will require two DCV tokens to be placed at the authoritative DNS provider. Similarly, a certificate with five hostnames in the SAN (including a wildcard) will require five DCV tokens to be placed at the authoritative DNS provider.

Complete DCV

Once you update your DNS records, you can either wait for the next retry or request an immediate recheck.

{{}}

TXT records used for DCV can be removed from your authoritative DNS provider as soon as the certificate is issued.
