The truth about typing "BFF" on Facebook revealed! — They claim your account is at risk if it doesn't turn Green.... It is Fake.. Don't Fall For it! [Full Details]

For the umpteenth time, I have come across a message that reads;

“Mark Zuckerberg, CEO of Facebook, invented the word BFF. To make sure your account is safe on Facebook, type BFF in a comment. If it appears green, your account is protected. If it does not appear green, change your password immediately because it will be hacked.”
“#Mark Zuckerberg. Facebook inventor, Make sure you do not think about your page or account, Type Bff in a comment, If it appears green, your account is protected and if it appears normal, you must change the password. Try it”‘

Yes, it is true that typing BFF into Facebook, makes the letters turn green, but then, this is in no way an indication that the security of your account is at risk. This makes no sense whatsoever.
This is, the word, “BFF” is a special word/comment chosen by Facebook, that upon being typed, it produces a brief visual animation to appear on the screen.
The letters colloquially mean “best friends forever”, and typing in the comment shows two hands “high fiving”. (After making the BFF comment. You can also tap on the GREEN BFF and you’d see two hands “High-fiving). That’s literally all there is to it. – See the screenshots below;


Reasons why some people are fooled into believing that the Almighty Facebook, or Zuckerberg, would introduce the “BFF” as a method of determining if your account is at risk, is just beyond us… Because it makes little sense. The messages does not describe or explain exactly how an account is at risk, rather just ambiguously states that they are.
The hoax bears resemblance to an earlier hoax from 2016 that claimed typing in #177 as a comment could reveal a green bar which indicates that your account “has been hacked”. Just like this rumour, that was also false.
The bottom line – this is a hoax. Please don’t share it or pass it on.
