A simple site-wide lockout (kinda like Basic HTTP auth).
Install using Composer:
composer require thepublicgood/simplepass
Set a new password with:
php ./artisan simplepass:set MY_PASSWORD
This will set a SIMPLE_SECRET value in .env.
When attempting to browse your site, you'll get redirected to /simplepass/auth and a password request. Use the password you set to unlock. If you ever need to log out, simply visit /simplepass/logout.
You can publish the configuration file with:
php ./artisan vendor:publish --provider=TPG\\Simple\\ServiceProvider
That will place a simplepass.php file in the config directory. Configuration options have been documented in the configuration file.
