Google gives you 2GB of Drive space for a short security checkup
You will be the one winning here because what you are getting from losing 2 minutes of your life is 2 more GB of space on your Drive plus better security from Google. The update on storage will roll out to accounts on February 28th and the promotion ends on February 17th so you better hurry.
NOTE: Google Apps and Google Apps for Education users can’t get the free storage for whatever reason.
