EmpowerID supports several one-time password delivery types, also known as Multi-Factor Communication options or Communication Types, from which users can choose for receiving verification codes when performing multi-factor authentication. Communication options include email, SMS and voice call. When users enroll for—and subsequently use—a multi-factor authentication method that requires verification codes, they select their preferred multi-factor communication option for receiving the code.

As an administrator you can configure which communication types are available by disabling those your organization chooses to not support.
