Known as “secret conversations”, Facebook announced that this feature aims to strengthen security and protection of users.
Facebook’s Vice President David Marcus said in a Facebook post, “Providing more ways for people to safely share is an important part of making the world more open and connected.”
Marcus added: “Whether you’re asking a doctor for medical advice, sending sensitive account information to your spouse, or even your Social Security number, it’s important to have options available for sharing these kinds of very sensitive messages.”
Facebook said that this will be an optional feature, because encrypted messages can only be viewed on one device. Thus, people can’t switch devices and still enjoy the new feature.
They also announce that its availability at the moment is limited because they’re still testing it, “during this test, we will gather feedback about the functionality, measure performance and introduce tools to enable you to report objectionable content to us,” Facebook wrote in a statement.
