Google allows users to sign into non-Google websites, applications, and devices with their Gmail account. This saves time during the account creation process, and makes joining new services quick and easy. But when you no longer use said service or app, it’s a good idea to revoke its access to your Google account.
How to Secure Your Google Account
13 Things You Can Do With the Google Settings App on Any Android Device
You can do this in your Google account’s Sign-in & Security page from a computer, but if you’re an Android user, there’s an even easier way. Since Google includes its own settings app on Android that pertains specifically to your account, you can quickly manage apps and devices that are currently signed into your Google account.
The first thing you’ll need to do is jump into your Android device’s Settings. Pull down the notification shade and tap the cog icon. Then, scroll down until you see the “Google” entry. It may be named slightly differently—it’s called “Google Services” on the LG G5, for example.
I’m using a Google Pixel XL for this tutorial, but the process should be the same on most other devices. The main exception here is the Samsung Galaxy S7 series, where Google Settings is a well-hidden option.
Once you’ve made your way into Google Settings, scroll down to the “Connected Apps” entry in the Services section. This is what you’re looking for, so go ahead and tap in.
By default, this section will show you all currently signed-in apps and devices. It’s worth noting that this doesn’t mean Android devices, bur rather the apps on your PCs, or web sites you occasionally visit in your browser. You can tap on the “All apps & devices” header to select more specific options, like just apps that are currently using your Google sign-in or Google Fit apps and devices.
Before we go any further, however, I want to clear up a bit of confusion. If you have a lot of signed-in services using your Google account, you may be confused as to why the “All apps & devices” section is significantly larger than the “Apps with Google Sign-in” section. Basically, the latter section is specifically for apps that use the Google+ Sign-in protocol, not just things that are currently signed in with your Google account. Both are things you’ll want to monitor. It’s confusing, I know.
With that out of the way, you can start picking through your stuff and removing account access to anything you no longer use. Tapping on an entry will display more information about what that app or service has access to. For example, ES File Explorer has access to the Google Drive API, Drive metadata API, Drive Per-File API, and my Profile Data. Since this is an app I no longer use (or trust), I want to disallow its access to those things.
And that’s the easy part: just tap the “Disconnect” button. A popup will appear, asking you to confirm your decision to disconnect the app from Google. Tap “Disconnect.” Poof! It’s gone.
That’s pretty much how it’s going to work across the board, regardless of whether you’re looking at all apps, apps that are using the Google+ sign-in, or apps with access to your Google Fit data—they’re all still accessing your Google account, and removing them is as simple as tapping a button. Do that for every app you want to remove, and you’ll be good. You may want to check back periodically to make sure this list stays cleaned up, too.
