Facebook will prompt its users to review their privacy settings within the next few weeks as part of a rollout of new and revised privacy features:

• An updated Privacy Checkup tool;
• An Off-Facebook Activity tool with a summary of data from third-party sites used for targeted ads, with an option to delete this data;
• A new Alerts for Third-Party Logins feature that allows you to see how your Facebook login is being used by other apps and services.
