Some Facebook users are being warned they could be locked out of their accounts if they don't opt in to a new security measure.
The social media giant is trying to protect accounts with "the potential to reach a lot more people than an average Facebook user" from "targeted attacks".
Hackers, Facebook said, are "often motivated to attack accounts that have a lot of followers, run important pages or hold some community significance".

"Facebook Protect" has been designed to allow people with such accounts to implement stronger security tools.
Users will also have their accounts checked for vulnerabilities, and help to resolve them.
Those who are eligible for the new measures will be prompted through the app, and via email.
A warning message within emails reveals anyone who is prompted and does not opt in risks being locked out of their account.
No action is required unless you get a notification that you’re eligible to enrol.
Facebook Protect is expected to be rolled out globally, with additional security steps being put in place.
All admins of Facebook pages will be required to go through publishing authorisations to ensure the page's security.
Page publishing authorisation asks people who manage these pages to secure their accounts with two-factor authentication and confirm their primary country locations.
