After the Cambridge Analytica scandal Facebook has been making a number of changes to the way our data is handled. the company has now added the ability to delete Facebook apps in bulk.
You can check which apps have access to your data by going to Settings > Apps and then seeing the apps that are authorized to view your data. You can now select multiple apps at once and then delete the ones that you do not want to have access to your information.
This new feature is available on both the mobile and desktop versions of Facebook. It looks like the feature is not available for everyone as yet, although it is expected to be rolled out to everyone soon.
It is worth checking to see which apps have access to your data. I just checked mine and was quite surprised to see a number of apps I didn’t even know about.
