Bug in FortiClient 7.x: Password Field Disabled After PIN Prompt

Hello,

I have encountered a recurring issue across all versions of FortiClient 7.x while trying to connect to my VPN. After entering my password and pressing "Enter," the password field gets grayed out and becomes unclickable.

At the same time, a new field labeled "Answer" appears, asking for a PIN between 4 and 8 alphanumeric characters.

When I input the PIN and click "OK," I receive an error message stating that the password must also be entered. Unfortunately, since the password field is disabled, I cannot re-enter it, making it impossible to proceed.

I’ve attached a screenshot for clarity.

Has anyone encountered this issue before? Is this a known bug in FortiClient 7.x?

Thank you in advance for your help!
