Facebook has issued a password reset for around 90 million users, after a flaw was found in Facebook’s code that impacted “View As”, a feature that lets people see what their own profile looks like to someone else.
According to a statement by Guy Rosen, VP of product management at Facebook, the flaw was discovered on Tuesday 25th September, and affected almost 50 million accounts. He said that the flaw would have allowed an attacker steal Facebook access tokens which they could then use to take over people’s accounts.
“Access tokens are the equivalent of digital keys that keep people logged in to Facebook so they don’t need to re-enter their password every time they use the app,” he said.
