Multi-Factor Authentication (MFA)

2-Factor authentication, also known as two-step verification and multi-factor authentication (MFA), adds an additional safeguard to your email account security by requiring a one-time password in addition to your email address & password for logging into your email account.

2-Factor authentication also allows setting up trusted devices such as mobile phones or mail clients to authenticate with a one-time password for devices that do not natively support 2-Factor Authentication (see Additional Steps below).

To setup 2-Factor authentication in your zMailCloud account, login to your webmail account (usually https://yourdomainname.zmailcloud.com/)  

Once logged in go to Preferences > Accounts.  Under Account Security click on Setup two-step authentication...:

Before you begin: 

Note that once 2 factor authentication is enabled, you will need to remove and setup any devices (including mobile devices) you are currently syncing to using an Application passcode (see Authenticating with Applications below) or your 2-factor authentication code.

To start, select Begin Setup:

Note that 2-step authentication does not replace your email address & password, it is an additional authentication step.  With 2-step authentication enabled on your account, you will be prompted to enter your one-time password each time you sign-in to your account:

Additional Steps: Authenticating with Applications

You can also create passcodes for devices that do not support 2-Factor Authentication.  Most mobile phones and mail clients will require setting up individual passcodes for these devices when 2-step authentication is enabled.  The below steps will show you how to do this:

Go to Preferences > Accounts > Application Codes > Add Application Code in your webmail account to begin.

Screen Shot 2017-01-18 at 1.12.30 PM

This will generate an application passcode:

Use this application passcode when setting up your account on your device as your normal password.

Once authenticated, you will see your device listed under Application Passcodes:

Congratulations!  You have successfully setup 2-factor authentication for your account. If you need further assistance, please submit a ticket.
