How to bind Socket to ID from client?

Question

JavaScript

Hello. There is such a situation. Site on Laravel, authorization on the site ONLY through Steam. The database stores all data, including SteamID. This is what needs to be passed to the socket.io server on node js. Moreover, so that it would be possible to accurately distinguish steamids absolutely exactly, so that it would not be possible to simply change the line in JS on the client side (on the site) and wow, you are logged in and can manage the admin panel (the admin panel also works through socket.io ). How to do it? again, a variant of the usual type transfer

socket.on('connection', function() {
    socket.emit('id', STEAMID);
});

does not fit the definition. Are there other ways? Database access is available on both sides.
