Welcome to the Community, @MiMojo.

Intuit is dedicated to securing your information with advanced security tools and systems to protect your account. 

You don't need to set anything up for MFA since it's automatically enabled for you. Upon logging in, a one-time confirmation code will be sent to your email or mobile device for additional security.

Additionally, multi-factor authentication can’t be turned off. It is a security feature that helps us safeguard your data and ensure that the person accessing the account is you. 

I hope this clears up any confusion on your end. 

Here's an article that can help you keep your information safe: Privacy and security in QuickBooks.
