The administrator of your account can activate a Two-Factor Authentication using SMS codes for the company account. This setting is available on the "Company account" page that you can access through the navigation menu on the left hand side. 

When you activate 2FA for the company account, all associated users will be required with their next login to add a telephone number to their account. All users will be notified via email if you activate or deactivate this security feature for your account.
