You, like many other people probably log in to other online services or apps using your Facebook account.
For the most part, it’s quick, convenient and saves you having to remember another set of login credentials.
However, this weekend reports from the New York Times and the Guardian revealed that a data gathering company with links to the Trump campaign “exploited” data from millions of Facebook users.
The company, Cambridge Analytica, created a personality test app called “thisisyourdigitallife”, which required people to opt in to use it.
By opting in, users granted permission for the app to scrape all of their personal data and data belonging to some of their friends.
According to the The New York Times, the data ended up being used by the Trump campaign.
While Facebook has denied the data was obtained due a security breach, it has admitted it knew irregularities were taking place with the app since 2015.
Facebook VP and Deputy General Counsel Paul Grewal wrote: “In 2015, we learned that a psychology professor at the University of Cambridge named Dr. Aleksandr Kogan lied to us and violated our Platform Policies by passing data from an app that was using Facebook Login to SCL/Cambridge Analytica, a firm that does political, government and military work around the globe. He also passed that data to Christopher Wylie of Eunoia Technologies, Inc.”
Lawmakers in both the United States and United Kingdom have asked Facebook CEO Mark Zuckerberg for answers.
And clearly Facebook has a lot to answer for.
But if you use Facebook, especially the login with Facebook option for any online services, now is probably a good time to see what apps have access to your Facebook data.
Here’s how to check your Facebook app settings
Click on the down arrow in the top right of your screen > Settings > Apps
Or you can click on this link
Tap on the three lines icon. On iOS this is located in the bottom right corner of the app. On Android it’s in the top left.
Then go to Settings > Account Settings > Apps > Logged in with Facebook
Once you’re there you will see all the services you’ve logged into using your Facebook account. You’ll probably be surprised just how many are listed.
