Is it RADIUS?

Which FML and FAC versions?

I followed this tech tip and it worked fine.

https://community.fortinet.com/t5/FortiMail/Technical-Tip-MFA-on-FortiMail-for-webmail-and-admin-logging/ta-p/253967

Token field appeared when I entered the password, and once token entered I could access the mailbox.

Try check if you applied the same steps in the tech tip.

Ah! it is also possible that the RADIUS secret is wrong. So try change it from both sides, and avoid using special characters for your initial setup attempt.
