To protect identities of users and their connections, SimpleX Chat has no user identifiers visible to the servers and the network – unlike any other messaging platform. Not only SimpleX doesn't use phone numbers or emails, as Signal and many other platforms, it also does not have any persistent identifiers to identify users - unlike many other messengers considered private - Session, Cwtch, Ricochet, Briar, Jami, etc., - all these platforms have global user identifiers, uniquely identifying their users and creating the risks of de-anonymising the users.

### Why is it bad for the users ### Why having users' identifiers is bad for the users?
When each user has a unique identifier on the platform, even if this is just a random number, e.g. as a Session ID, it creates risks that whoever gains access to the platform data can observe how the users are connected and how many messages are transmitted between them, and then correlate this information with the existing public social networks, determining the real identities of some users. Even with the most private messengers built on top of Tor network, having a persistent identity means that if you talk to two different users via the same profile they can prove that they communicate with the same person, as they use the same address to send messages.

SimpleX platform avoids these risks by not having any user identity in its design - so even if you talk to two different people from the same chat profile, they would not be able to prove they are talking to the same person - only that user profiles look the same. And we are planning to add a feature allowing to have a different display name for each contact you connect to - quite a few users asked for it.
