Apparently, after over 3 years, it appears that neither Quickbooks or Navy Fed gives a crap to fix this issue. Personally, I think it is Intuit's responsibility to resolve it. Their system simply isn't saving the necessary authentication information from Navy Federal, so with each connection, Navy Fed thinks it is a new login from a new browser and keeps asking for MFA.
Usually, this would be done with a browser cookie (log in>remember browser>and you won't be asked for MFA for some amount of time), but QBO must not function that way. I've just joined QBO for my business that uses a NFCU business account and I'm already thinking about cancelling it because of this issue. Absolute trash that after 3 years this is still an issue with connecting to the largest credit union in the nation.
