Facebook has admitted having a “security issue” with nearly 50 million accounts which had their “access tokens” compromised. The social media giant has reset tokens for another 40 million accounts as a “precaution.”
The issue affected nearly 50 million accounts, which would require users to re-enter their passwords. The security issue was discovered by the company’s engineers on Tuesday. Hackers have been apparently able to fetch the so-called “access tokens” – digital keys, which allow a user to stay logged into Facebook and to not re-enter their passwords each time they use the application.

“Our investigation is still in its early stages. But it’s clear that attackers exploited a vulnerability in Facebook’s code that impacted “View As”, a feature that lets people see what their own profile looks like to someone else,” the tech giant said in a statement.
