'loginAction' => false,
'unauthorizedRedirect' => false,
'checkAuthIn' => 'Controller.initialize',
'storage' => 'Memory', // means you ask aws for each query... so I suggest you to use my plugin cakephp-redis

/* so once Basic grant access, you'll find X-Token header with your token
* then add this X-Token hader with value Bearer XXX ( the previous token )
* so storage keep you session in redis instead of asking for new grant access
'storage' => [
	'className' => 'Awallef/Redis.Redis',
	'redis' => [
		'prefix' => 'your_app_id:token:',
	]
],

User Model

you can create a copy of the user in your system by setting create config argument to true

// auth settings
...
// create users - OPTIONAL
'create' => true,
...

So you will need a User Model that matches aws fields or by using fieldsMapping argument congito-auth needs to have write permission on id if you rename AWS 'sub' filed into id

// auth settings
...
'fieldsMapping' => [
	'Username' => 'username',
	'Enabled' => 'is_active',
	'UserStatus' => 'status',
	'sub' => 'id',
	'Groups' => 'role'
],
...

Model Entity:

protected $_accessible = [
	'*' => true,
	'id' => true
];

Challenge

if you recieve a challenge error such as:

SMS_MFA
PASSWORD_VERIFIER
ADMIN_NO_SRP_AUTH
NEW_PASSWORD_REQUIRED

redirect, or ask user to provide responses in request data object:

// + username + password => required 
// 'USERNAME' and 'SECRET_HASH' => will be filled for you
$request->data['Challenge']['responses'] // must be filled

please refer to : aws php SDK #adminrespondtoauthchallenge
