I didn't activate two-step verification cause the process was a little bit of a hassle (I'm lazy). But when upgrading to last iOS update I was prompted to activate two-step authentication and I was a really smooth process.

If everything goes fine I guess they will prompt everyone to switch to the new method on the next update.
