However, four people are involved in the effort let these apps continue as stand alone apps, the report said.

Facebook said, “We’re working on making more of its messaging products end-to-end encrypted, and considering ways to make it easier for users to connect across networks.”

A spokesperson reported, “There is a lot of discussion and debate as we begin the long process of figuring out all the details of how this will work.”

According to the NYT report, after the changes, a Facebook user will be able to send an encrypted message to someone who has only a WhatsApp account.

End-to-end encryption protects messages from being viewed by anyone except the participants in the conversation.
