Turn off login notification email for Facebook chat on a Mac I have setup Facebook chat in Messages on my Mac. The problem is that every time Messages logs in to chat, I receive an email saying:


  It looks like someone logged into "Facebook Chat" on Sunday, March 2,
  2014 at 11:07am. If this was you, please disregard this email. If this
  wasn't you, please secure your account, as someone else may be
  accessing it.


I understand that this is essentially a Facebook security mechanism to warn users about unauthorised access to their account. My question is: Is there a way to mark Messages as an 'authorised application' so that I don't get this notification email every time?
Go to your Facebook

Settings-Security and disable the notifications there
