A private messenger must remain usable when a device changes or a group grows. Session's design emphasizes metadata privacy, but adoption depends on contact setup, message delivery, and account recovery.
Create disposable identities, exchange messages and media, start a small group, and test on the platforms your contacts use. Simulate a lost device and restore using the current Session recovery guidance. Keep recovery material offline and never paste it into a support chat. Compare message delays, notifications, accessibility, and what history is actually restored.
Privacy claims should be evaluated alongside the operating model and current documentation. Do not move an important conversation until all participants can reconnect after a phone change and understand what data is stored locally versus delivered through the network.
