A lot of websites allow you to use your Google account as a middle man to not only sign in to their services but sharing some basic information about you as well. Some of the information shared through your Google account includes the email address, Name, country and language. Even though Google claims that they will never share this data without notifying you and asking for your permission first, it would be a good idea having a place to check which websites/apps have gained these shared permissions over the time.
Indeed, Google has an option called “Call app permission” where you can find all the connected apps. To access, simply go to this web address. If you already signed in, you will see a full list of apps that have been connected to your Google account in a second.
Click on any of the apps on the list to view the detail information about the app. Pay more attention to those that have “full access to your Google Account” because when an app has full account access, it can see and modify nearly all information in your Google Account (but it can’t change your password, delete your account, or pay with Google Wallet on your behalf). And click Remove to revoke that access if you don’t think it’s necessary.
That’s about it. Have a safe and happy surfing day.
