Nexus Two Factor Authentication

Description


Nexus Two-Factor Authentication (2FA) enhances security by incorporating dynamic PIN verification into the Nexus and Vista authentication processes. To activate 2FA, an authenticator app on a smartphone is required. This can be any app that supports the TOTP (Time-Based One-Time Password) standard, such as Google Authenticator or Microsoft Authenticator.



2FA Activation


To activate Two-Factor Authentication (2FA) for an identity (User Login), follow these steps:

Nexus Administrator


The following activation procedure must be performed by the administrator.

  1. Click on "Account" located in the top right corner of the Nexus GUI interface, then select "Identities".

  2. Locate the identity for which you want to activate Two-Factor Authentication (2FA), and either double-click on the corresponding List Card or select "Edit Identity" from the List Card Actions menu.
