Google's One Tap Two-Factor Authentication Will Show Info On Who's Logging In. I know. I promised not to browbeat you with demands that you turn on two factor authentication on all your sites and devices. But, here I go again. This time, I am bringing good news. Google is making it easier and more informative. In fact, Google will now notify you every time someone tries to log in from a new device. As FutureLawyer is always testing new devices, I see this message all the time. It is comforting to know that Google has my back. You will not only be warned about someone trying to hack your account, you will know where they are doing it from. No codes required. Two Factor authentication. Learn it. Do it. NOW. Don't make me come over there.
