Changes to Domain-Vetted Authentication

Going forward, there will be two small changes to the Domain-Vetted Authorization process for customers using the DNS or FILE method. 

These changes will come into effect on March 15th, 2017 and will not affect existing certificates.

The validation process for the following SSL Certificates will be affected:

  • Sectigo Positive SSL
  • Sectigo Essential SSL
  • Sectigo Essential SSL Wildcard
  • Sectigo Positive SSL Wildcard
  • Sectigo SSL
  • Sectigo SSL Wildcard
  • QuickSSL
  • QuickSSL Wildcard
  • RapidSSL
  • RapidSSL Wildcard
  • Thawte SSL123

DNS Authentication Method

Once an order is submitted, a DNS string and timestamp are immediately generated.

Previously, these two elements were then used to add a CNAME record to the zone records of the domain. 

Now, this DNS string and timestamp will be used to add a TXT record to the zone records of the domain. 

File Authentication Method

Once an order is submitted, a text file is immediately generated, and should be uploaded to the website's main directory. The vendor will check the website for this file and, after confirming it has been uploaded, validate the certificate. 

Previously, there was no industry standard for the file name or it's location within the websites directory.

Now, the file name and location have been standardized. 

Please ensure that the file is uploaded to the correct location:
