                callback(null);
            }
          }
        } 

Thank you

You have invalid JavaScript you have label and function declaration, which should be put in an object like this:

var x = {
   login: function() {
   }
};

which should be part of object in second argument which is options object.

.terminal(function(command) {

   if (command === 'register') {
   }
}, {
   login: function(...) {
      ...
   }
});

and for your exact problem on having login command, that login you in, you need to invoke login method like this:

} else if (command == 'login'){
   term.login(function(user, password, callback) {
      // to get the token you should send user and password to the server
      if (user == 'demo' && password == 'secret') {
        callback('SECRET TOKEN');
      } else {
        callback(null);
      }
   });
} else if (term.token()) {
   // here are commands that will only work after user login
   // but you need to know that user may add token in developer tools
   // so you should use additional check if token is valid by sending token
   // to the server, or if you're invoking command on the server then just
   // send the token and validate it there
} else {
   term.error('invalid command');
}
