I've had "fun" time using two factor in 1Password, and for now I'm turning it off.
The overhead of always having to use two factor with my iOS 1Password negates the utility of 1Password for iOS passwords.
Pretty much every time I tap the iOS password link I had to jump out of 1password, open Authy, get the OTP for 1Password, then go back into 1Password, and by then I was back to my manual workflow before iOS 12.
What would make a whole lot more sense would be to use two-factor to trust a new install of 1Password on a device. After installing 1Password on a new device, prompt me for the OTP and then never ask me again. Or maybe only ask me every two weeks, like 1Password TouchID on the Mac.
Because asking me for a OTP every, single, time I use it... shoot me now. Back to the old school for me, for now.
