Late last month, Facebook disclosed a massive security vulnerability that it claimed affected some 50 million login tokens, but details were somewhat thin on its impact pending further investigation.

This will delete everything you've ever put on Facebook - profile information, photos, status updates, timeline posts - but won't include messages sent via Facebook Messenger.
The company said users' credit card information was not exposed.
This messaging breach could have impacted 400,000 users, including political groups. But three errors in Facebook's software enabled someone accessing "view as" to post and browse from the Facebook account of the other user.
Beginning with a set of accounts controlled by the attackers, the exploit jumped from friends of those users to friends of friends, ballooning to the eventual total of 30 million accounts via an automated script.
Access tokens work as digital keys, letting those who hold them log into Facebook accounts without entering a password.
On September 25, the trend was identified as an attack, prompting programmers to close the vulnerability, which happened within two days, the tech chief said.
Facebook has set up a link where people can go and check if they were affected.
