[PDOException] SQLSTATE[28000] [1045] Access denied for user ‘homestead’@’localhost’ (using password: YES) looks like same error different is not showing any file line number.

The reason of Access denied for user ‘homestead’@’localhost’ laravel 5 error is caching-issue of the .env.php file cause Laravel 5 is using environment based configuration in your .env file.

Why Environment Configuration :-

It’s often helpful to have different configuration values based on the environment the application is running in. For example, you may wish to use a different cache driver locally than you do on your production server. It’s easy using environment based configuration.

Laravel utilizes the DotEnv PHP library by Vance Lucas. In fresh Laravel installation, you will see a .env.example file in the root directory of your application. If you are installing Laravel via Composer, this file will automatically be renamed to .env. else, you need to rename the file manually. For more about Environment Configuration

default .env file looks like :-

APP_ENV=local
APP_DEBUG=true
APP_KEY=your_key

DB_HOST=localhost
DB_DATABASE=homestead
DB_USERNAME=homestead
DB_PASSWORD=secret

CACHE_DRIVER=file
SESSION_DRIVER=file
QUEUE_DRIVER=sync

MAIL_DRIVER=smtp
MAIL_HOST=mailtrap.io
MAIL_PORT=2525
MAIL_USERNAME=null
MAIL_PASSWORD=null
