The text discusses the importance of secure and private messaging for protecting identity and sensitive information. It highlights three top-rated secure messaging apps: Signal, Threema, and WhatsApp. Signal is considered the best due to its open-source protocol, fast encryption, and complete implementation of end-to-end encryption best practices. Threema offers anonymity and a business model, while WhatsApp is widely used and secure enough for daily use, but has concerns around Meta's history of privacy violations. The article also excludes several other messaging apps from the list due to various reasons such as lack of end-to-end encryption or poor user experience.
