Can you even use tofu with gemini? With gemini, it seems the only two factor you could use is authy? It doesn't show any other two factor option you could use when on security page... which is why i choose authy.
I just took a look at tofu on app store. I never heard of it. Again for two factor, i only heard of is google authenticator... which i used before and authy. I heard of microsoft authenticator as well but never heard of other ones. But can you use tofo on any site that allows two factor?
I want to use two factor on coinbase and gemini. At the moment, im using authy now for gemini and it seem to be fine. But how do i do backup in case something happens to my phone?
