I found this resolution online, and it worked for me
Log in to your Bank of America account, go to security, third party, revoke Quicken
Log out of Bank of America
Log back into Bank of America
When you get that pop-up directing you to go to Quicken within 10 minutes, hit decline
After logging into Bank of America, log back out
Go to Quicken
Pick any of your Bank of America accounts and add it to connect, then choose Bank of America
Sign in to Bank of America using your username and password
You should get a confirmation code
Enter that, and you should be able to get back to being able to get back to normal access
