. Check if your data was compromised. You can do this by visiting Facebook's Help Center and clicking on "See If You Were Affected by Cambridge Analytica." Enter your email address and name, and Facebook will tell you if your data was shared.

. Change your Facebook password. This is a good idea to do even if you're not sure if your data was affected.

. Enable two-factor authentication for your Facebook account. This will add an extra layer of security to your account and make it less likely to be hacked.

. Review your privacy settings. Take some time to review your privacy settings and make sure that you're only sharing the information you want to share.

. Limit the amount of personal information you share on Facebook. Be careful about what information you share on Facebook, especially personal information like your date of birth, phone number, and address.

. Be aware of the risks of using third-party apps. Third-party apps can access your Facebook data, so be careful about which apps you give permission to access your account.

. Delete any apps that you don't use. Take a look at the apps you've authorized to access your Facebook account and delete any that you no longer use.

. Contact the FTC if you believe your information was misused. If you believe that your information was misused by Cambridge Analytica or another company, you can file a complaint with the Federal Trade Commission (FTC).
