Two-Step Authentication - Two-Step Authentication is a method of providing a second verification of account ownership before a user can log into their account or connect to third-party clients and/or devices. For example, when a user has Two-Step Authentication enabled for their account, the SmarterMail login page will require their primary account password and a secondary verification of account ownership before the user can log into webmail. The second method of verification will be provided to the user through popular authentication apps, like Google or Microsoft Authenticator, or through a recovery email address. When this feature is enabled for a domain, the Domain Administrator can override the system setting and choose whether to enable or force Two-Step Authentication for their users. Two-Step Authentication can be Disabled, Enabled or Forced for the domain.
