I know this is practically a year after the fact, but I found this thread when having the same issue myself.
I also had two-factor disabled, chrome settings were fine, etc, and yet all of a sudden found myself having to "verify my identity" every single time I got timed out. Once in a while is fine, expected even, but so consistently? Absolutely obnoxious.
Obviously their responses weren't very helpful, but I suddenly realized that perhaps my NordVPN was possibly at fault. It's been the reason I have had trouble going to most federally run websites (????) as well as some others, so yesterday I finally thought to add all intuit domains to my "whitelist".
Lo and behold, I turn on my computer this morning and it doesn't make me verify my identity!! After like a week of that nonsense, it was an incredibly welcome reprieve. I sincerely hope in the year since you first posted that you've figured out how to circumnavigate this annoyance, but I wanted to comment on it just in case someone like me comes along and maybe hasn't fiddled with their VPN settings. (QBO probably updated some small thing in their website security, making it not as compatible with VPNs or something.)
