Deniec access - laravel 5.1 [migration]

At first, I got access denied error in my command prompt, so I modified .env:

DB_HOST=localhost
DB_DATABASE=homestead
DB_USERNAME=homestead
DB_PASSWORD=''

Now, in command line doing php artisan migrate it gives me "Access denied for user ''@'localhost' to database 'homestead'". What could possibly cause this error as I've set password to null? Using XAMPP.
