Why Signal is hard to archive
Signal is built so that no one but the people in a conversation can read it. That's why many clients trust it, and it's also why Signal conversations are so often missing from a firm's books and records.
Every Signal message, call and attachment is end-to-end encrypted, and Signal keeps almost nothing about its users. When subpoenaed, Signal says it can provide only the date an account was created and the date it last connected. There is no carrier copy and no server copy to fall back on.
See Signal's published subpoena responses →Disappearing messages have long been part of Signal, and since 2021 users can turn them on by default for every new chat, with timers from seconds to weeks. A record that deletes itself is a record your firm no longer has.
In the SEC's off-channel enforcement actions, Signal is named alongside iMessage and WhatsApp as an app regulated employees used on personal devices for business conversations that weren't preserved. Financial firms were first, but the same duty applies anywhere a chat may be needed for an audit, an investigation or a litigation hold.
