This article explains the functionality of Two-factor authentication policy. Two-factor Authentication (2FA) is an additional layer of security, which requires end-users to respond to a second authentication challenge when logging into $unite or ShareSync
To enable 2FA policy for all users, log into CONTROL PANEL > Account > Security Polices > Two-factor authentication (2FA).
Check the Activate 2FA for users box. You may automatically select or deselect all users on the account that need to have 2FA by clicking Select all or Deselect all. This allows to either enable Two-factor Authentication for all users on the account or deselect all users to then manually enable it for specific users only.
Frequency tab allows you to set how often users with 2FA enabled will be challenged for extra authentication. The possible options are: on every login, daily, weekly, monthly, when logging from a new device.
You can enable/disable 2FA per user in user's settings. Navigate to Users, click on the Display Name of the user > User Info > Edit 2FA settings
To enable Two-factor authentication for the user, check the Enable two-factor authentication for this user box. Under How to authenticate section choose DoubleSafe app Push notification, SMS text message, Voice call or DoubleSafe app One-time passcode.
