Ever seen one of these posts on Facebook:

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 in green, change your password immediately because it will be hacked.

Don’t believe it – it’s a scam.

In 2017 Facebook added a new feature to automatically colour specific words.   These include “congratulations,” “xoxo,” and “BFF” (best friends forever).

It has nothing to do with security – just making Facebook a little more colourful.
