Facebook messenger end-to-end encryption coming like that of Whatsapp.

So guys this post is about the new security encryption on Facebook message, I came across it on Twitter so I felt I should share. Facebook just said they would be releasing the end-to-end encryption   for a limited number of users. Wait!  What really is end-to-end encryption?  Most of us are already using it on whatsapp right? According to Wikipedia it is "End-to-end encryption (E2EE) is a system of communication where only the communicating users can read the messages. In principle, it prevents potential eavesdroppers – including telecom providers, Internet providers, and even the provider of the communication service – from being able to access the cryptographic keys needed to decrypt the conversation.

The systems are designed to defeat any attempts at surveillance and/or tampering because no third parties can decipher the data being communicated or stored. For example, companies that use end-to-end encryption are unable to hand over texts of their customers' messages to the authorities." so with that back to the gist, going by what the product manager Tony Leach said, he update would be made available to all users around the world , without fear that government or and third-party individual would have access to that conversation. 

We know this feature had been on whatsapp since April, but it is available by default. On Facebook messager user are allowed to set the encryption them self, by turning on the ‘Secret conversations Mode’ to encrypt a conversation. The product manager Tony Leach, explained that since people use Facebook messager for not just one device, but from Personal computers, Web browsers etc, making it  available by default would limit users from using Facebook messenger from and device at any place as before. 

It also allows for messages to be deleted after a specific time in the ‘secret conversations’ after the receiver of the message had read it. 

Or nahh? Too late? 

So what do you think guys ? A good idea? Or nahh or too late after WhatsApp had done theirs?  Leave your opinion in the comments section .
