The Facebook plan was delivered by CEO Mark Zuckerberg, according to the New York Times in his report, quoted Saturday. The process will involve recoding basic software from three applications to ensure they can be operated as planned.
A WhatsApp user will be able to, for example, send text messages to Instagram users for the first time without having to change applications.
Recoding the software will also involve activating end-to-end encryption (E2E) in all three applications, according to Mike Isaac of the New York Times. While all WhatsApp messages will use that security feature, which prevents anyone, including Facebook itself, from intercepting or censoring messages.
Facebook Messenger only supports E2E in special "secure conversation" mode, which is not active by default and must be activated separately for each chat, while Instagram has no encryption at all.
