Domain validation explained
Full guides: email, DNS record, file on your website. Not completing? What to check.
Before a certificate can be issued, the authority must confirm you control the domain. There are three ways to do this, and the same method applies to your common name and every SAN.
Email validation
The authority emails a code to an address at your domain (for example
admin@, webmaster@ or hostmaster@). We will show
you which addresses are available. You can request this email to be resent from the
control panel.
DNS validation
You add a DNS record (a CNAME or TXT entry) to your domain. Once we place the order, the exact record you need is emailed to you and shown in your account — it cannot be known before the order is placed. DNS changes can take a short while to appear.
File validation
You upload a small text file to a specific path on your website. As with DNS, the exact file name and contents are provided after the order is placed, by email and in your account.
