I have the same problem when signing in to QB online. It will sometimes go for a couple of weeks of not requiring verification and then I will have to verify two or three times in the same day. It gets very frustrating. A coworker has the same computer system I do and has never had to verify. In response to your explanation above, the two-step verification is disabled, I always use the same computer (imac), the same browser (chrome), and I have never cleared my cache.
Thanks.
