Google offered 2GB of free Drive space last year if you were willing to complete its Security Checkup for your account. This year, it's doing the same. All you have to do is check over your recovery email and phone number, confirm the list of connected devices and glance over the list of apps and sites that have permission to access your account. It takes about two minutes, even less if you're familiar with the process from last year. Once you're all done, you'll receive a confirmation and those 2GB of cloud storage will be added to your account soon after. Heck, it's free, so there's no reason not to do it. And even if you glanced over things last year, you'll receive an additional 2GB of storage for doing so once more.
