To properly celebrate Safer Internet Day, Google is offering a nice perk for users who complete a quick security checkup. If you're willing to make sure your account recovery info is up to date, review recent log-in activity and confirm the list of apps that access your account details, the folks in Mountain View will add 2GB to your total Drive space. You have to complete the quick process before February 17th, and the extra gigabytes will appear around the end of the month. The offer is only open to personal accounts, though, and while Google Apps for Work and Google Apps for Education users can't boost their space, it's probably not a bad idea to double-check those settings anyway.
