PDOException SQLSTATE[28000] [1045] Access denied for user 'homestead'@'localhost'

I am new in Laravel 5.2.

I am getting following error:

[PDOException]
 SQLSTATE[28000] [1045] Access denied for user 'homestead'@'localhost' (usin
 g password: YES)

While I execute following command:

 php artisan migrate 

I am running application using vagrant on windows PC. Please let me know why I am getting above error.

Thanks in advance.
