Coincidentally, I'm in the same predicament with Facebook, itself.

I can't log in to Facebook because Facebook wants approval from the Duo Mobile 2FA app. The 2FA app won't approve the login because it wants a code that can only be obtained by logging in to Facebook.

Solution: Deleted both Duo Mobile and Facebook apps. Moved on with my life.

isn't that like throwin the baby out with the bath water? i've never had problems with duo mobile, but then i don't use FB so i've never seen how it behaves with FB. so dump FB, but why dump duo mobile?

Because the only thing I used it for was to login to Facebook. All of my other 2FA is through other methods.
