I have been thinking about this vague memory lately. Somewhere between 2011 and 2013, I used to go on an application on Facebook called "Video Chat Rounds" (article: <a href="https://www.adweek.com/performance-marketing/video-chat-rounds-random" rel="nofollow">https://www.adweek.com/performance-marketing/video-chat-roun...</a>). It was an app on which you could video chat with other Facebook users (basically the same thing as Omegle). It used to be an app on the Facebook platform.<p>Back in the day I was still a kid and thought it was pretty cool to see and talk to people all over the world. There is one thing that is bothering me. I have this memory that sometimes, after I had just been on the app and went back to my Facebook homepage, I was suddenly logged into a random Facebook account from a person I had never heard of before. As a kid, that felt really illegal and scared me.<p>Now, many years later, I am wondering whether this memory is something which really happened or which I made up. It seems very unlikely you could get logged in as another user (without entering any credentials) on a platform like Facebook. However, I do believe it is a real memory.<p>My question is the following one: could this memory be real and if so, what did Facebook do wrong?
Idk about your specific case but I <i>do</i> know being logged in to another user can happen on buggy servers and has happened to others.<p>Servers have to keep track of which clients are logged into which users, usually via a session token. Memory corruption or a race condition can cause one token to be associated with another user.
Definitely possible. Steam had something similar a while back caused by caching issues [1]. I have no idea about Facebook specifically though.<p>[1] <a href="https://www.forbes.com/sites/insertcoin/2015/12/25/steam-is-randomly-logging-users-into-other-peoples-accounts-and-exposing-their-information/?sh=7efffa1e301d" rel="nofollow">https://www.forbes.com/sites/insertcoin/2015/12/25/steam-is-...</a>
