Put your mouse on the “Settings” button in the top blue bar, towards the right side.

You do not need to click this button/link, there will be a drop down menu like below. Click the “Application Settings” link.

You will see the most recent applications, and a drop down menu to select more views.

Select “Allowed to Post” from the list. 

You will see a list of applications that are allowed to post updates to your stream, without asking for your permission. Prepare to be surprised, I keep checking this portion and still didn’t know that I had one other application that could post without prompting! Go ahead and click “Edit Settings” for the applications that should not post updates without Prompting.

  You need to change the “Additional Permissions” for the application.

Revoke the “Additional Permissions” and you are good to go.

You can revoke the additional permissions from all the applications that you do not use, or you do not want to allow to post to your streams. I know of people who allowed over 300 applications to post without prompting. This meant that anything that they did on Facebook, or even their desktop in some cases, was available for the entire world to see, without their knowledge.

Protect yourself. Start now!
