External Account Binding is an ACMEv2 feature that allows you to associate an ACMEv2 account with an external account such as a database account. In Certificate Enrollment Gateway, External Account Binding credentials are used to restrict ACMEv2 access to permitted ACMEv2 clients

To create and manage External Account Binding credentials for ACMEv2 enrollment with Certificate Enrollment Gateway, you must use the EAB Utility. The EAB Utility is available as a separate download package on Entrust TrustedCare.

To use External Account Binding, Certificate Enrollment Gateway must be using an external database to store data, and External Account Binding must be enabled for ACMEv2.
