If you were logged out of Facebook tonight, you are not alone. Facebook states that users were logged out of the social site due to a “configuration change.”

From reports on Twitter and DownDetector the majority of users logged out were using a mobile device.

Facebook said they are aware of the issue and believe a configuration change caused the mass logou

“We’re looking into reports that some people are currently having to login again to access their Facebook accounts,” Facebook told BleepingComputer. “We believe this was due to a configuration change and we’re working to get things back to normal as quickly as possible.” 

Many have posted concerns that Facebook suffered a security incident that caused them to reset the login sessions. While the resetting of sessions would be a good way to perform a mass-logout of Facebook users, there is no indication at this time that a breach occurred.

“On January 22, a configuration change caused some people to be logged out of their Facebook accounts. We investigated the issue and fixed it for everyone earlier today. We’re sorry for the inconvenience.” – a Facebook company spokesperson
