Moving from WhatsApp to Signal: A good idea?

This article compares Signal and WhatsApp from a privacy and security perspective, noting both use end-to-end encryption while Signal minimizes metadata (e.g., via Sealed Sender) and adds privacy features like disappearing messages, relayed calls, screen lock, screen security, incognito keyboard, and registration lock; WhatsApp collects more metadata shared with Meta. It recommends Signal for users prioritizing privacy, acknowledges trade-offs with WhatsApp’s larger user base and social features, and provides practical steps to harden Signal and verify group membership.
