Interoperability is coming.
There were rumors that Facebook was going to make its messaging products interoperable, but now it appears they’re about to be a reality. At F8, Messenger’s head of consumer product Asha Sharma said that in the future, users will soon be able to send messages across Facebook’s three different messaging platforms: Messenger, Instagram and WhatsApp.
This interoperability is just one of many features of the new Messenger. All messages will also be end-to-end encrypted, which is part of Facebook’s recent privacy-focused mantra. Sharma said that the inter-app messaging will work similar to how people make calls on phones today. You don’t need to know if your friend is on Verizon or T-Mobile, you can just call them. It’ll be the same on any of Facebook’s messaging services — just say you’ll want to talk to your friend, and that message will get to him or her on whatever service they use.
