Facebook users are getting freaked out by alerts claiming “unrecognized devices” have accessed their accounts, but when they check their login history, nothing looks off. No new sessions, no weird locations, nothing.
A Reddit thread on r/facebook shows people running into the exact same problem. One user posted the text from the warning that said, “An unrecognized device was detected on your account. We recommend comparing your keys with your contacts to secure the chat.” They checked everywhere and found zero evidence of an actual breach.
The comments filled up fast with others saying they’re seeing identical notifications, some on desktop where they don’t even use mobile apps. The weirdest part? Their “Where you’re logged in” section looks totally clean.
Meta’s help center explains that login alerts normally trigger when someone signs in from a new browser or device you haven’t used before. You can manage these under Accounts Center → Password and security → Login alerts. Pretty standard stuff when it works correctly.
But these current alerts don’t match that pattern. People are getting warnings about unrecognized devices while their activity logs stay empty. The Messenger version mentions comparing encryption keys, which hints that this might be related to how Meta now handles end-to-end encrypted chats rather than someone actually breaking in.
The wording makes it worse. “Unrecognized device was detected on your account” sounds like a live hack, not some backend sync issue. So users panic, check everything, find nothing wrong, and end up confused.
Still, treat any security alert seriously. Check your Accounts Center or Security settings for sessions you don’t recognize, log out anything suspicious, change your password if needed, and enable two-factor authentication.
If your login history looks fine and the only red flag is that one chat banner, you’re probably hitting the same bug others are seeing. But until Meta clarifies what’s happening, users are stuck trying to figure out if this is a real threat or just broken software.
