(Opens in a new window) Read Our Slack Review Other messengers, like Facebook Messenger and Telegram, have E2EE as an option and only in some contexts, but for WhatsApp and Signal it's the default. Not even the people at WhatsApp (and by extension, Meta) can read your messages. That means only the sender and the intended recipient can read messages. For one thing, it's built on the tried-and-tested Signal Protocol for sending and receiving end-to-end encrypted (E2EE) messages. Trust is the foundation of any secure messaging app, and WhatsApp does a lot to earn your trust. Still, its future is less than certain-especially as law enforcement continues to attack its security. With a foundation on excellent technology and a huge built-in audience, it's still an excellent free app, and it's the biggest player in the secure messaging business. Since then, it has been bought by Meta (formerly and, let's be honest, forever Facebook), upgraded its security, and then entered a long period of mild stagnation that persists to this day. The solution was over-the-top messengers that used your data connection to send texts, and WhatsApp was the first mobile messaging platform to gain critical mass. And forget about group conversations, or easily chatting with people in other countries. In the bad old days, texting plans were pricey and you could easily rack up hefty charges if you burned through your allotted amount.
