Two-factor authentication adds an extra layer of security and prevents access to your users’ session even if someone knows their password. A combination of two different factors is used to achieve a greater level of security:

1) something they know, a password.
2) something they have, a device – such as a smartphone – with an authentication app installed.

You can use one of the following authenticator apps to proceed. These apps are available across a wide range of platforms:
– Authy
– Google Authenticator
– Microsoft Authenticator

Each time a user sign in to its remote session it will need its password and a verification code available from its mobile phone. Once configured, the authenticator app will display a verification code to allow him or her to log in any time. It works even if its device is offline.

Two-factor authentication is available for RDPlus Web portal only. This authentication mode does not support login through Remote Desktop client. Since 2FA authentication only works with the Web portal with HTML5 and RemoteApp connections. RDP connections are denied for 2FA enabled users.
