Now they have decided to make the chats of Facebook Messenger end to end encrypted but this option will be optional for everyone. As we all are familiar about end to end encryption, later it was performed on Whatsapp by the Facebook Community and this feature is also brought to the Facebook Messenger.
End to end encryption will be optional to use. The best part of the feature is that you can even turn it off, if you don't want it. You can set timer for example after 20 minutes your message should self destruct. So after exactly 20 minutes your end to end encrypted messages will vanish from your device.
One important thing to share is, if you are using your mobile phone for using end to end encrypted feature then, you cannot watch those messages from any other device for example your laptop or pc.
This feature is not yet launched worldwide but it is available for limited users as, it is just an testing feature. If this feature will be loved by most of the users then it will be obviously launched worldwide.
The most important thing that I liked the most is that we can on or off the feature whenever we want, it is not compulsory for you to use this feature.
