1Password 8 not seeing that I already have two factor enabled for a site.

I was in your position many years back. I took them about one a week. Many less sites offered it back then. I remember how tedious this was. It was not a huge undertaking but not fun either. Wishing you luck if you decide to move over. That said, I am ancient and I suspect the process would be 100 times easier nowadays.

Cheers,
