This added level of security is almost necessary now a days with all the logging in we do from various places. Had Hotmail used something like this I would not have had to delete my account. it doesn't bother you all the time either. If you are logging in from home or any safe computer, just tell it to remember the authentication for 30 days and you are good for a month. Well planned and works very smoothly. Set this up via your Google account settings/other settings/2 step security.

I am enjoying learning different ways to utilize Google Authenticator for all of my accounts. Just be sure to clearly label them if you have more than one.
