Account Security Feature: Approved User Email Domains
CertCentral Administrators can now specify what email domains users can create a CertCentral account for. This helps prevent emails from being sent to non-approved, generic email domains (@gmail.com, @yahoo.com), or domains owned by third parties. If a user attempts to set or change a user email address to a non-approved domain, they receive an error.
Find this setting in Settings > Preferences. Expand Advanced Settings, and look for the Approved email domains section.
Note: This does not affect existing users with non-approved email addresses. It only impacts new users and email changes made after configuring this setting.
