According to one of the Facebook engineers, a version of Messenger that’s fully end-to-end encrypted by default remains years away.

Jon Millican, Facebook’s Messenger privacy software engineer, said, “While we have made progress in the planning, it turns out that adding end-to-end encryption to an existing system is incredibly challenging and involves fundamentally rethinking almost everything.”

Facebook spokesperson says the company expects to see some progress on interoperable messaging this year.
