How to Block third-parties from accessing your Gmail

Gmail has of recent been on-the-spot for allegations that third-party app developers are allowed access into your inbox, following a WSJ article claiming that software developers “scan hundreds of millions of emails of users who sign up for email-based services.” Users who signed up for email-based services  such as shopping price comparisons and automated travel-itinerary planners could have had their private messages read.

How to block third-party access to your Gmail

To avoid third-party readers, Google says to visit its Security Checkup page to review what permissions you’ve given in the past to non-Google apps. These are basic steps you can follow to block this access.

  • Click on your account information in the upper right hand corner of the Gmail screen. You can as well type in your browser to lead you to the info page.
  • Click Sign-in & Security and scroll down to the Apps with account access section.  This is where you can keep track of which apps or services have the permission to access your account, and it is from here that you can remove the ones you no longer use or trust.
  • Click the Manage Apps link. Here, you will see three sections: Google’s own apps such as Chromecast, Google Chrome, Google Assistant Enabled Devices; the apps and sites you use to sign into Google; and the third-party apps with account access. You may not have any trouble with any of the apps that you see in these sections but it’s a good to ensure  that you’re comfortable with each of them.
  • A click on any will show you when access was given, what kind of access it has, and a Remove Access button – which you can utilize at your wish.
