We use tools like cookies to help keep Facebook safe, secure and easy to use. Cookies support or enable security features. For example, with
login approvals if someone logs into your account from a browser you’ve never used before, we’ll block them and ask for more information. They also help us implement
login notifications, so you can be alerted when your account is accessed and disable any active Facebook sessions.
Besides helping to keep unauthorized people from logging into your account, we also use cookies to help make sure the people or machines that access Facebook don’t violate our policies. For example, certain information on Facebook is
public and therefore can be accessed by anyone on the internet. These cookies help us understanding the volume and frequency of requests so we can detect and stop people or machines from “scraping” information from our site.
We also use these tools to make Facebook easier to use, like when you mistype one character of your username or password. If you’ve already logged into Facebook from the same browser, we’ll give you easier options to correct your typo since we know you’ve successfully logged into Facebook before.
