Twitter launched encrypted messaging Wednesday, offering select users the ability to communicate more securely. But its new service is much more of a baby step than a giant leap forward.
For starters, it lacks basic protections that security experts consider essential for shielding messages from hackers and other prying eyes. Senders and receivers must also be subscribed to Twitter’s Blue service for $11 a month ($8 for desktop-only) or otherwise affiliated with an organization “verified” by Twitter for $1,000 a month plus $50 per user.
