Interesting question - I haven't had to try it yet. My scrapers are all read-only at the moment, and (afaik) none of the UK banks require two-factor in any form for that kind of operation. Potentially using Twilio (http://www.twilio.com http://www.twilio.com) you might be able to have an application which receives the two-factor request itself and handles it. It'd make the process async though, which wouldn't be ideal.
