Signal

brew install --cask signal v8.15.0

Encrypted messaging app with a focus on privacy and open-source security.

Why you might care

Signal uses end-to-end encryption by default for all messages, calls, and group chats, and publishes its security code for independent review. It's free, open-source, and doesn't collect or sell user data, making it the go-to choice for privacy-conscious users and those in high-security environments.
