The use of single sign-on and multifactor authentication for accessing the Comodo Certificate Manager is available to any subscriber that also operates an Identity Provider in the InCommon Federation. See this wiki page for details.
The InCommon Certificate Service issues unlimited Extended Validation (EV) SSL/TLS certificates at no additional cost to subscribers. Because EV certificates require additional levels of validation for the requesting organization, our partner Comodo must handle all of the paperwork as well as the validation process for EV certificates.
You can use one Certificate Request Form for multiple orders submitted at the same time. Otherwise, each order requires its own Certificate Request Form.
