+# Stickee Laravel SFTP Dual Auth
+
+Provides a dual-authentication filesystem driver for [Laravel](https://laravel.com/).
+The built-in sftp driver supports key-based login and password-based login, but not both at the same time. This driver provides that capability.
+
+## Installation
+
+Install with composer:
+
+`composer require stickee/laravel-sftp-dual-auth`
+
+If you don't use auto-discovery, add the SftpDualAuthServiceProvider to the providers array in *config/app.php*
+
+```
+Stickee\LaravelSftpDualAuth\SftpDualAuthServiceProvider::class,
+```
+
+## Usage
+
+You can noew use *sftp_dual_auth* as a disk driver in *config/filesystems.php*
+
+```
+ 'disks' => [
+
+        'local' => [
+            'driver' => 'local',
+            'root' => storage_path('app'),
+        ],
+
+        'my_dual_auth' => [
+            'driver' => 'sftp_dual_auth',
+            'host' => env('MY_SFTP_HOST'),
+            'username' => env('MY_SFTP_USERNAME'),
+            'password' => env('MY_SFTP_PASSWORD'),
+            'privateKey' => env('MY_SFTP_PRIVATE_KEY'),
+            'root' => env('MY_SFTP_ROOT', ''),
+        ],
+
+    ]
+```
+
+See the [League Flysystem SFTP documentation](https://flysystem.thephpleague.com/docs/adapter/sftp/)  ([GitHub](https://github.com/thephpleague/flysystem-sftp)) for information on the configuration options.
