Node.js undefined properties

I'm trying to create a log in window. My code is simple.

var employees = {
	'1' : {
		firstName: '',
		lastName: '',
		login: 'qwerty',
		password: '12345',
	},
	'2' : {
		login: 'asdfg',
		password: '12345',
	},
};

app.post('/main', function(req, res) {
	if (!req.body) return res.sendStatus(400);
		console.log(req.body);
	for (var key in employees) {
		console.log(key['login']);
		console.log(key['password']);
		if ((key.login == req.body.login) && (key.password == req.body.password)) {
				res.render('main');
		} else {
			app.get('/', function(req,res) {
				res.send(createIndexPage());
			});
		};
	};
});

Why key.login and key.password return undefined? And why else block does not run when if statement is wrong?

Look at what the value of key actually is:

var employees = {
  '1': {
    firstName: '',
    lastName: '',
    login: 'qwerty',
    password: '12345',
  },
  '2': {
    login: 'asdfg',
    password: '12345',
  },
};

for (var key in employees) {
  console.log(key);
}

It is the property name (as a string), not the value of the property.

console.log(employees[key]['login']); will give you what you are looking for.
