We are using Fortitoken mobile for 2FA. I started assigning the tokens to the users. They were able to add them to their smartphones. On Windows 7, they open Forticlient to VPN, and enter their username and password, it does not ask for the token. When I enter my username/password, it says does not ask for the token and shows "wrong credentials" .
On my windows 10 computer, when I connect to VPN, it it asks for my token.
