Passwords only offer a single layer of protection to a user’s identity. The most complex passwords can be compromised by:
- Using the same password on more than one website or application.
- Weaponized software downloaded from the internet or received via email.
- Clicking on links to malicious web sites.
Mimecast native 2-Step Authentication adds an additional layer of protection by denying access with just a password. Enabled, your administrators and users will need a password and a one-time verification code to access Mimecast. Administrators can choose how 2-Step verification codes are received / generated. The following options are available:
- Via email
- Via SMS
- Via a 3rd party code generator (e.g. Google Authenticator, Duo, Authy, Symantec VIP Access, FortiToken, and many more).
Depending on your Mimecast subscription, you may have access to Mimecast SMS Services.
2-Step Authentication has the following benefits:
- The additional layer of security reduces the risk of a your administrator and user accounts becoming compromised.
- Group-based configuration provides the flexibility to enable this for all users or selected users only.
- Works with your existing Cloud or Domain authentication configurations to allow you to enhance security while minimizing impact .
- Email or SMS delivery of verification codes.
- Support for 3rd party verification code generators to get a verification code.
- Using a secure, standards-based implementation for compatibility with a wide range of 3rd party verification code generators.
- Simple self-service registration process for 3rd party verification code generators reducing IT complexity.
- Adaptive location based support provides the option to only require a 2nd form of verification when users attempt to login from outside of your trusted networks.
Supported Mimecast Applications
2 Step Authentication is supported for both administrator and end user access, including access to:
- The Administration Console
- Mimecast Personal Portal
- Case Review Application
- Mimecast for Outlook v7 and later
- Mimecast Mobile 3.5.2 and later
- Mimecast for Mac 2.8.9 and later
Consider the following when configuring 2 Step Authentication:
- The Partner Portal does not currently support 2 Step Authentication.
- If you are using earlier versions of our Mimecast for Outlook, Mimecast Mobile, and Mimecast for Mac applications, you'll be prompted to upgrade if 2-Step Authentication is enabled.
- If both 2-Step Authentication, and Enforce SAML Authentication are enabled in the same profile, SAML will take preference. In this case the user should authenticate with the Identity provider defined in the authentication profile. See the Understanding Enforce SAML Authentication for End User Applications page for further information.
