Google has several ways of managing different aspects of your account. The new My Account page is a hub of useful tools that you can tweak to modify the security or privacy of your account. It even has a Security Checkup and Privacy Checkup to quickly audit your settings.
The My Account page has existed for a while but, as tech site Ghacks points out, this new version makes it much easier to find the options that you need. Most of what's here isn't totally new, but it is a lot easier to find your way around.
If you haven't done so before, we highly recommend going through the Security and Privacy Checkup wizards at least once. Even if you're comfortable with your Google account the way it is, it can't hurt to know what's exposed and what isn't.
