I don’t know. I changed my default browser in settings but Safari continues to show up on my iPhone.

I downloaded Google Authenticator but I don’t know what to do with it. I’m terribly confused! I just don’t know what I’m doing, and I don’t know what I am supposed to do. I did get a recovery key however. Please help me if you can. I get so confused when I read your instructions. The instructions say to click on so and so and I don’t know what to do or where to find what I’m supposed to click on.
