Following the news that 50 million people's Facebook accounts have been hacked, here's the social media giant's advice on the next steps to take.
- 90 million accounts have been automatically logged out, but no one needs to change their passwords.
- If you are having difficulty logging back in - for example because of a forgotten password - you should visit Facebook's help centre.
- If you have not been logged out automatically, but want to log out as a precaution, visit the "Security and Login" section which lists all the places you are logged in to Facebook.
- Use the one-click option to log out of Facebook on all PCs and devices you may have accessed it on.
