I have 2FA turned on for my E*Trade account. Normally this works, though it's always a bit clunky because Quicken always reports first a failure to connect and, it's only after I tell Quicken to update E*Trade a second time that Quicken presents me the box for my 2FA code. But after I enter the code, Quicken does download the transactions.
Today, Quicken is not presenting me with the modal box for entering my 2FA code at all.
