What is Two-Step Authentication?

Two-Step Authentication adds a second verification step when a user logs in to the web portal, or when a they register an agent, the Outlook add-in, or a mobile device for the first time.

With Two-Step Authentication, users will be sent an authentication code through an authenticator mobile app, text message, or email, depending on their own configuration settings. They must then enter their authentication code along with their username and password before they can access the Nimbox system.

Two-Step Authentication applies to:

  • Web app — you will need to enter an authentication code each time you log in to the web portal.
  • Desktop app — you will need to enter an authentication code when first registering the app.
  • Outlook add-in — you will need to enter an authentication code when registering the Outlook add-in, when opening a new Outlook profile, or when changing credentials.
  • Mobile apps — you will need to enter an authentication code when accessing a mobile app for the first time. You’ll also be asked to configure a passcode within the app.
