If 2-Step authentication is enabled, logging in to Mimecast requires an additional step. You'll enter your email address, choose between a Mimecast cloud or domain password, and enter your password as normal. However once that is completed, you'll be asked for a verification code. Your IT department will decide how you receive this verification code. It can be via:

  • Email
  • SMS
  • 3rd party application (e.g. Google Authenticator). 




If you're configured to receive verification via email, you'll see a screen like the one below once you have successfully entered your password:


Your email address is displayed on screen as the delivery destination. 

  1. Enter the Verification Code you've received.
  2. Click on the Verify button.




If your'e configured to receive verification codes via SMS, you will see a screen like the one below once you have successfully entered your password:


The last 2 digits of your cell phone number are displayed as the delivery destination.

  1. Enter the Verification Code you've received.
  2. Click in the Verify button.


3rd Party Application


If your'e configured authentication via a 3rd party application, the next time you log in, you'll have to register your application. Registration is the process of linking the application on your cell phone with Mimecast, so that the application generates verification codes we can use to verify your identity. 


To register the application:

  1. Download an authenticator application (e.g. Google Authenticator) from your app store.
    Ask your IT department for guidance if you're unsure.
  2. To display a six digit verification code, either:
    • Scan the QR Code displayed using the authenticator application.
    • Press the Enter key.
  3. Log in using your userid and password.
  4. Click on the Next button.
  5. Enter the Verification Code.
  6. Click on the Log In button.


Keep your authenticator application on your phone. You'll need it each time you log in. If you can't log in, contact your IT department.


Lost / Stolen Devices


Should the device you've used to set up an authenticator application with Mimecast is lost or stolen, contact your IT department as soon as possible. They'll be able to force a re-registration for you.
