Zoho Account MFA Modes

Zoho Account MFA Modes

I have a Zoho Account and when I log into my account and go to Profile - Multi-factor Authentication - MFA Modes, it shows a message MFA ENFORCED BY ADMIN in Green colour at top right side of the screen.

As far as I know, I am the admin of the account and I cannot find anywhere where I can turn this off or change the settings. 

Please let me know as to how to change the above setting, in case I require to do so.

Also let me know as to what category and sub category do I select to post for Zoho Account related or OneAuth related issues as I cannot find any for same.
