I just completed building a Laravel 8 project with MySQL as my database and with Sail/Docker and PhpMyAdmin. This is what I found out what the default username and password is for the default connections. Please note that this was on a development machine in my local envirnment and is recommended to always chance the dafault password.
Laravel 8 Default MySQL password is:
username: root
password: [blank]
Yes, the password is left blank.
you can change the default password in the .env file
DB_CONNECTION=mysql
DB_HOST=mysql
DB_PORT=3306
DB_DATABASE=api5
DB_USERNAME=root
DB_PASSWORD=
Also, look in the config/database.php file:
'driver' => 'mysql',
'url' => env('DATABASE_URL'),
'host' => env('DB_HOST', '127.0.0.1'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'forge'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),
'unix_socket' => env('DB_SOCKET', ''),
