An iPhone user who uses the Facebook app is suddenly forced to log out.



On Friday, January 22, 2021, a user using the Facebook app from the iPhone was forced to log out of his Facebook account. This situation quickly became a

trend on Twitter, but Facebook explains that the cause of this mysterious logout incident is 'a configuration change.'

From around the night of January 22, 2021, all Facebook users using the iOS app were forced to log out of their accounts and had to log in again. It seems that the first user to be logged out was a user using two-step authentication using SMS .

On the overseas bulletin board Reddit, there is a thread that says 'Is there anyone who was asked to sign in to the Facebook app again even though I do not remember signing out in the first place?' I'm complaining about problems such as 'I can't log in because the verification code isn't sent!'

Did anyone else get prompted to “Sign In” again to their Facebook app after NEVER signing out in the first place?: Facebook

Eventually all users could re-login to their Facebook account, but users with two-step verification would have a very late arrival of the code sent via SMS and would not be able to log in again. It seems that it was necessary to upload a 'face photo'.



In response to this, Facebook is working to resolve the issue of 'I'm looking for reports of logged out users. I have to log in again to access my Facebook account' on my official account as soon as possible. I have a statement. '


A Facebook spokeswoman also told technology media Engadget, 'We are aware that some people are currently having problems accessing Facebook. This issue was caused by a configuration change. It is believed that there is, and we are working to get it back to normal as soon as possible. '

Facebook hasn't disclosed details about this 'configuration change.' However, Facebook reports that the issue of 'configuration changes' has been resolved around 6am on Saturday, January 23, 2021 local time. In addition, the Facebook service itself did not go offline, and only some iPhone users could not log in to their accounts for a while.
