Facebook staff have "master password" to any account
Mark Zuckerberg's former speechwriter Katherine Losse has reportedly warned that Facebook administration has access to the data of their clients.
Katherine Losse continues to unmask the administration of the world's biggest social network. She has told that when she joined Facebook in 2005, customer support staff were each handed a “master password,” which allowed them to log in as any Facebook user and access all their messages and data.
Facebook administration denies this and claims that at present moment only the technical support service and the security service have access to the passwords.
