Each participant in a Conversation is represented by a User object and must be authenticated by the Client SDK. In a production application, you would typically store this user information in a database.
Execute the following commands to create two users,
Bob who will log in to the Nexmo Client and participate in the chat (Conversation).
nexmo user:create name="Alice" nexmo user:create name="Bob"
This will return user IDs similar to the following:
User created: USR-aaaaaaaa-bbbb-cccc-dddd-0123456789ab
There is no need to remember this user ID because you will use user names (instead of user IDs) to add them to the conversation.
