We've probably all experienced the pain of accidentally sharing a status update or photo with an entire contact list, instead of just friends. But a new Facebook privacy update is intended to cut down on incidents of unwanted sharing.

Moving forward, Facebook will set all new users' default audience to "Friends," instead of the previous "Public" option.

First-time posters will receive a pop-up reminder to choose an audience. If you leave it up to fate, the website will automatically set your preference to Friends.

For existing users, Facebook will start testing an expanded privacy checkup tool, "which will take people through a few steps to review things like who they're posting to, which apps they use, and the privacy of key pieces of information on their profile," Facebook said.

"We want to do all we can to put power and control in people's hands," the social network said. "This new tool is designed to help people make sure they are sharing with just the audience they want." Of course, you can change the individual settings of new or old posts at any time, so even if you've overshared, it's easy to pull back later.

Back in October, Facebook announced that its teens would have the option to make their posts public. However, to prevent them from accidentally making private information available for the world to see, the default setting for new accounts of those ages 13 to 17 is "friends."

Today's announcement, meanwhile, comes after CEO Mark Zuckerberg introduced a more granular control center at April's F8 developer conference, which lets users decide what data, if any, users share when logging in to Facebook on a third-party site.

Users prompted with the familiar blue "Login with Facebook" button can now access a comprehensive list of data-sharing permissions, which they can choose to let the app share or not. Also, members will be able to log into applications anonymously, and other Facebook users will no longer be able to share your data.
