Other than being more streamlined and offering offline access to codes, is there any additional benefit in terms of security for updating from the two-step method to two-factor?

I much prefer having the recovery key that is provided with two-step; I don't see that the two-factor method offers a recovery key.

Having any security feature associated with either my landline or mobile phone makes me feel uncomfortable for multiple reasons, some that have already been articulated by others here plus some more I can't really put my finger on, except to say that both landline and mobile phones seem inherently untrustworthy to me.

Am I just being paranoid?
