There's a few chat applications which can be used to communicate:
Secure
- SimpleX - Bit more secure then Signal, as it has built in privacy features at the protocol level (such as message padding). By default users /chats don't have constant identifiers either. Allows for anonymous profiles and supports multiple profiles.
- Signal - Good replacement for normal “text messaging”. Share your username instead of phone number.
- Delta Chat - Supports multiple profiles.
Less Secure
- Keybase - Supports multiple profiles, allows managing teams. Roughly an alternative to discord/slack. Currently owned by Zoom. Keybase has access to metadata to understand who is talking to who. https://book.keybase.io/docs/chat/crypto#metadata
Treat As Public Chats
- Matrix - Fluffychat client is recommended, as it supports multiple profiles. Setup a home server and disable federation to prevent metadata being copied around.
Note Homeserver owners can join encrypted chats and impersonate users by adding their own device key to the target users account. This is a bug that is being fixed in 2026 by requiring clients to confirm device keys of other users. https://element.io/blog/verifying-your-devices-is-becoming-mandatory-2/
