Validation of PositiveSSL and EssentialSSL Certificates

Comodo (now Sectigo CA) does not require any other verification procedures for PositiveSSL and EssentialSSL Certificates other than validation of your domain ownership. It can be done by either receiving the validation email or uploading a certain text file into a particular directory of your website (/.well-known/pki-validation/) or adding a certain CNAME record to the DNS zone of your domain.

If you have activated the certificate with or indicated as FQDN in your CSR code, please make sure that the file is available via . In this case, is considered to be under your control as well.

Content of the file shouldn't be changed in any way, as Comodo (Sectigo) validation system is case sensitive.
