Using MS Authenticator for MFA with FortiCLient

Not knowing if MS Authenticator is working. I've enabled one of the two free tokens and tried with different OTP Apps, none of them was able to read the generated QR code. As we use MFA also for PC login and other webservices like owa, we ended up with duo. They have integration for Forti SSL VPN and this is working very well not only with mobile app push, but also with HW tokens like Ubikey. Duo is free for 10 users and you can create a trial account for 60 days.
