Encryption is only one part of trust
Members care about whether a private conversation stays private, but they also care about whether the chat still works when they change phones or open a browser for the first time.
That means secure messaging UX has to cover device approval, recovery, and trust-change warnings without feeling like a developer tool.
Recovery should feel natural
Aphrodite has been moving more of the secure-messaging recovery flow into the places where people actually expect it, especially inside Messages on iPhone.
That is the right direction. In practice, members do not think in terms of key material, continuity hashes, or backup inventory. They think in terms of whether they can open the chat and continue.
Trust needs visible review points
Device approval, continuity warnings, QR verification, and account-level device activity all exist to help members notice when a secure setup changes.
The security model gets stronger when those review points are visible and simple instead of hidden in technical settings pages.
