import chainlit as cl @cl.password_auth_callback def auth_callback(username: str, password: str): # Fetch the user matching username from your database # and compare the hashed password with the value stored in the database if (username, password) == ("admin", "admin"): user = cl.User( identifier="admin", metadata={"role": "admin", "provider": "credentials"} ) cl.user_session.set("user", user) return user

else:
    return None

app_user = cl.user_session.get("user")
await cl.Message(f"Hello {app_user.identifier}").send()

Me too, facing similar issue, password_auth_callback fails thus on_chat_start is not called

My Code:

@cl.password_auth_callback
def auth_callback(username: str, password: str)-> Optional[cl.User]:
    # Fetch the user matching username from your database
    # and compare the hashed password with the value stored in the database
    if (username, password) == ("admin", "admin"):
        user = cl.User(identifier=username)
        print(f"Authenticated user {username}")
        return user
    else:
        return None

@cl.on_chat_start
def on_chat_start():
    print("The chat session has started!")
    chat = create_chat_system()
    print("Chat system created")
    cl.user_session.set("chat_system", chat)

Which chainlit version do you use? This can happen due to older versions. I had the same issue. Upgrade to the latest version with: pip install --upgrade chainlit
