Thank you for taking the time to visit the Community and adding to this discussion, though I apologize for the trouble you
Unfortunately, the Multi-Factor Authentication (MFA) process is something we need to go to the bank for help with. This requirement comes directly from the bank. Being that you and/or others have already gone to them without any luck, I do have a suggestion. You can try changing your security preferences from the bank website. Normally this wouldn't be my first suggestion, but it does sound to me like your security preferences need to be refreshed. If possible try turning off the MFA, and see if that makes a difference in your Quicken. If you can not figure this out on your own, call Chase for guidance with this process.
