Forticlient vpn 7.4.1 MFA issue

[tweenbee]

Hi All, 

I encountered a strange issue on my forticlient VPN version 7.4.1.

previously I have setup custom IPSEC VPN in my Fortigate FG500e with RADIUS/NPS user groups, and for a long time there were no issue.

in the few days back, the vpn client start having strange behavior, after I put my password is should have been keeping the password and asking for MS authenticator token. but now the forticlient remove the password making it blank and asking for authenticator.

when I put my authenticator token, it keep notifying "please provide password" :

for the record I'm using version 7.4.1.1736

the VPN is IPSEC not SSL

this issue only happens using RADIUS authentication, when using fortigate local user the vpn can be connected normally.

please help

A quite similar issue has been fixed in 7.4.3.

When using IPsec VPN with RADIUS authentication (Microsoft Entra ID), FortiClient (Windows) clears password field when asking for MFA.

Try update to 7.4.3 and see if it helps.
