Bank of America seems to have changed its MFA for its Health Savings Accounts. I get the following error when I try to download transactions: You are using a multi-factor security process at Bank of America - Health Accounts that prevents Quicken from connecting. For example, a token or one-time code. You would need to change this bank security setting to connect. (FDP-192).
No way to turn off or change MFA on the Bank of America side that I can find. I notice that they now require an email code to log in.
