App researcher Jane Manchun Wong says Twitter is working on end-to-end encryption for direct messages sent over the social network.
“Twitter is bringing back end-to-end encrypted DMs. Seeing signs of the feature being worked on in Twitter for Android,” Wong tweeted. The tweeted included code strings highlighting references to encryption keys.
Twitter CEO Elon Musk later replied to Wong’s tweet with a winking face emoji hinting that the feature is in development.
End-to-end encrypted DMs would bring the same type of messaging as apps like WhatsApp and Signal. Such encryption keeps a conversation between users, with no possibility of outsiders being able to monitor the conversation.
Twitter began work on end-to-end encryption for Twitter DMs back in 2018, but the feature was never released.
