Introduction
A modern and framework agnostic authorization and authentication package featuring roles, permissions, custom hashing algorithms and additional security features.
The package follows the FIG standard PSR-4 to ensure a high level of interoperability between shared PHP code.
The package requires PHP 7.2.5+ and comes bundled with a Laravel 7 Facade and a Service Provider to simplify the optional framework integration.
Have a read through the Installation Guide and on how to Integrate it with Laravel 7.
Create a user
Sentinel::register(array(
'email' => 'john.doe@example.com',
'password' => 'foobar',
));
Authenticate a user
Sentinel::authenticate(array(
'email' => 'john.doe@example.com',
'password' => 'foobar',
));
Features

Inter-account throttling with DDoS protection | Basic | Advanced |
Installation
The best and easiest way to install Sentinel is with Composer.
If you have installed Composer globally run the following:
composer require cartalyst/sentinel "^4.0"
Otherwise you'll have to manually download the composer.phar
file:
curl -sS https://getcomposer.org/installer | php
php composer.phar require cartalyst/sentinel "^4.0"
Now you are able to require the vendor/autoload.php
file to autoload the package.
Integration
Cartalyst packages are framework agnostic and as such can be integrated easily natively or with your favorite framework.
Laravel 7
The Sentinel package has optional support for Laravel 7 and it comes bundled with a Service Provider and a Facade for easy integration.
After installing the package, open your Laravel config file located at config/app.php
and add the following lines.
In the $providers
array add the following service provider for this package.
Cartalyst\Sentinel\Laravel\SentinelServiceProvider::class,
In the $aliases
array add the following facades for this package.
'Activation' => Cartalyst\Sentinel\Laravel\Facades\Activation::class,
'Reminder' => Cartalyst\Sentinel\Laravel\Facades\Reminder::class,
'Sentinel' => Cartalyst\Sentinel\Laravel\Facades\Sentinel::class,
Assets
Run the following command to publish the migrations and config file.
php artisan vendor:publish --provider="Cartalyst\Sentinel\Laravel\SentinelServiceProvider"
Migrations
Run the following command to migrate Sentinel after publishing the assets.
Note: Before running the following command, please remove the default Laravel migrations to avoid table collision.
php artisan migrate
Configuration
After publishing, the sentinel config file can be found under config/cartalyst.sentinel.php
where you can modify the package configuration.
Native
Sentinel being framework agnostic, by default, ships with the implementation for the Illuminate Database component.
In order to use it, make sure you require the necessary dependencies by running:
composer require illuminate/database illuminate/events symfony/http-foundation
// Import the necessary classes
use Cartalyst\Sentinel\Native\Facades\Sentinel;
use Illuminate\Database\Capsule\Manager as Capsule;
// Include the composer autoload file
require 'vendor/autoload.php';
// Setup a new Eloquent Capsule instance
$capsule = new Capsule;
$capsule->addConnection([
'driver' => 'mysql',
'host' => 'localhost',
'database' => 'sentinel',
'username' => 'user',
'password' => 'secret',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
]);
$capsule->bootEloquent();
The integration is done and you can now use all the available methods, here's an example:
// Register a new user
Sentinel::register([
'email' => 'test@example.com',
'password' => 'foobar',
]);

Arguments
Key | Required | Type | Default | Description |
---|---|---|---|---|
$model | true | string | null | The roles model class name. |
Example
Sentinel::getRoleRepository()->setModel('Acme\Models\Role');
Create a new role.
Create a new role.
Arguments
Key | Required | Type | Default | Description |
---|---|---|---|---|
$attributes | true | array | null | The role attributes. |
Example
$role = Sentinel::getRoleRepository()->createModel()->create([
'name' => 'Subscribers',
'slug' => 'subscribers',
]);
Example Response
{
name: "Subscribers",
slug: "subscribers",
created_at: "2014-02-17 02:43:01",
updated_at: "2014-02-17 02:43:37",
id: 2
}
Assign a user to a role.
$user = Sentinel::findById(1);
$role = Sentinel::findRoleByName('Subscribers');
$role->users()->attach($user);
Remove a user from a role.
$user = Sentinel::findById(1);
$role = Sentinel::findRoleByName('Subscribers');
$role->users()->detach($user);
Permissions
Permissions can be broken down into two types and two implementations. Depending on the used implementation, these permission types will behave differently.
- Role Permissions
- User Permissions
Standard - This implementation will give the user-based permissions a higher priority and will override role-based permissions. Any permissions granted/rejected on the user will always take precendece over any role-based permissions assigned.
Strict - This implementation will reject a permission as soon as one rejected permission is found on either the user or any of the assigned roles. Granting a user a permission that is rejected on a role he is assigned to will not grant that user this permission.
Role-based permissions that define the same permission with different access rights will be rejected in case of any rejections on any role.
If a user is not assigned a permission, the user will inherit permissions from the role. If a user is assigned a permission of false or true, then the user's permission will override the role permission.
Note The permission type is set to
StandardPermissions
by default; it can be changed on theconfig
file.
Administrator Role
{
"name" : "Administrator",
"permissions" : {
"user.create" : true,
"user.delete" : true,
"user.view" : true,
"user.update" : true
}
}
Moderator Role
{
"name" : "Moderator",
"permissions" : {
"user.create" : false,
"user.delete" : false,
"user.view" : true,
"user.update" : true
}
}
And you have these three users, one as an Administrator, one as a Moderator and the last one has both the Administrator and Moderator roles assigned.
User - John Doe
{
"id" : 1,
"first_name" : "John",
"last_name" : "Doe",
"roles" : ["administrator"],
"permissions" : null
}
This user has access to everything and can execute every action on your application.
User - Jane Smith
{
"id" : 2,
"first_name" : "Jane",
"last_name" : "Smith",
"roles" : ["moderator"],
"permissions" : {
"user.update" : false
}
}
- Can view users.
- Cannot create, update or delete users.
Note: The use of
user.update : false
demonstratesPermission Inheritance
, which applies only when usingStandard Mode
(inheritance is disabled, by design, when usingStrict Mode
). When a permission is defined at the user-level, it overrides the same permission that is defined on the role. Given the above example, the user will be denied theuser.update
permission, even though the permission is allowed on the role.
User - Bruce Wayne
{
"id" : 3,
"first_name" : "Bruce",
"last_name" : "Wayne",
"roles" : ["administrator", "moderator"],
"permissions" : {
"user.create" : true
}
}
- Can create, update and view users.
- Cannot execute delete users.
This is a special user, mainly because this user has two roles assigned. There are some things that you should know when assigning multiple roles to a user.
When a user has two or more roles assigned, if those roles define the same permissions but they have different values (e.g., one role grants the creation of users and the other role denies it), once any of those role permissions are denied, the user will be denied access to that permission, no matter what the other roles have as a permission value and no matter which permission type (standard
or strict
) is being used.
This means that for you to allow a permission for this specific user, you have to be using standard
permissions and you have to change the user permission to grant access.
Usage
Permissions live on permissible models, users and roles.
You can add, modify, update or delete permissions directly on the objects.
Storing Permissions
Permissions can either be stored as associative arrays on the Eloquent user
or role
by assigning it to the permissions
attribute or using designated permission methods which make the process easier.
Array
Grant the user user.create
and reject user.delete
.
$user = Sentinel::findById(1);
$user->permissions = [
'user.create' => true,
'user.delete' => false,
];
$user->save();
Grant the role user.update
and user.view
permissions.
$role = Sentinel::findRoleById(1);
$role->permissions = [
'user.update' => true,
'user.view' => true,
];
$role->save();
Designated methods
Note
addPermission
andupdatePermission
will default to true, calling addPermission('x') will grant the user or role that permission, passing false as a second parameter will deny that permission.
Grant the user user.create
and reject user.update
.
$user = Sentinel::findById(1);
$user->addPermission('user.create');
$user->addPermission('user.update', false);
$user->save();
Remove user.delete
from the user.
Note Removing a permission does not explicitly mean rejection, it will fallback to permission inheritance.
$user = Sentinel::findById(1);
$user->removePermission('user.delete')->save();
Update existing user.create
and reject user.update
$role = Sentinel::findRoleById(1);
$role->updatePermission('user.create');
$role->updatePermission('user.update', false, true)->save();
Note 1:
addPermission
,updatePermission
andremovePermission
are chainable. Note 2: OnupdatePermission
, passingtrue
as a third argument will create the permission if it does not already exist.
Checking for Permissions
Permissions checks can be conducted using one of two methods.
Both methods can receive an argument of either a single permission passed as a string or an array of permissions.
hasAccess
This method will strictly require all passed permissions to be true in order to grant access.
This test will require both user.create
and user.update
to be true in order for permissions to be granted.
$user = Sentinel::findById(1);
if ($user->hasAccess(['user.create', 'user.update']))
{
// Execute this code if the user has permission
}
else
{
// Execute this code if the permission check failed
}
hasAnyAccess
This method will grant access if any permission passes the check.
This test will require only one permission of user.admin
and user.create
to be true in order for permissions to be granted.
if (Sentinel::hasAnyAccess(['user.admin', 'user.update']))
{
// Execute this code if the user has permission
}
else
{
// Execute this code if the permission check failed
}
Note You can use
Sentinel::hasAccess()
orSentinel::hasAnyAccess()
directly which will call the methods on the currently logged in user, incase there's no user logged in, aBadMethodCallException
will be thrown.
Wildcard Checks
Permissions can be checked based on wildcards using the *
character to match any of a set of permissions.
$user = Sentinel::findById(1);
if ($user->hasAccess('user.*'))
{
// Execute this code if the user has permission
}
else
{
// Execute this code if the permission check failed
}
Controller Based Permissions
You can easily implement permission checks based on controller methods, consider the following example implemented as a Laravel filter.
Permissions can be stored as action names on users and roles, then simply perform checks on the action before executing it and redirect on failure with an error message.
Route::filter('permissions', function($route, $request)
{
$action = $route->getActionName();
if (Sentinel::hasAccess($action))
{
return;
}
return Redirect::to('/')->withErrors('Permission denied.');
});

Throttle
There are three types of throttling.
global
throttling will monitor the overall failed login attempts across your site and can limit the affects of an attempted DDoS attack.ip
throttling allows you to throttle the failed login attempts (across any account) of a given IP address.user
throttling allows you to throttle the login attempts on an individual user account.
Each type of throttling has the same options. The first is the interval, this is the time (in seconds) for which we check for failed logins. Any logins outside this time are no longer assessed when throttling.
The second option is thresholds, this may be approached using one of two ways.
- The first way, is by providing a key/value array, the key is the number of failed login attempts, and the value is the delay in seconds before the next attempt can occur.
- The second way is by providing an integer, if the number of failed login attempts outweigh the thresholds integer, that throttle is locked until there are no more failed login attempts within the specified interval.
On this premise, we encourage you to use array thresholds for global throttling (and perhaps IP throttling as well), so as to not lock your whole site out for minutes on end because it's being DDoS'd. However, for user throttling, locking a single account out because somebody is attempting to breach it could be an appropriate response.
You may use any type of throttling for any scenario, and the specific configurations are designed to be customized as your site grows.
Exceptions
Cartalyst\Sentinel\Checkpoints\ThrottlingException
Methods | Parameters | Description |
---|---|---|
setDelay | Cartalyst\Sentinel\Users\UserInterface $user | Sets a user object on the exception. |
getDelay | .. | Retrieves the user object that caused the exception. |
setType | string $type | Sets a user object on the exception. |
getType | .. | Retrieves the user object that caused the exception. |
getFree | .. | Retrieves time the throttle is lifted. |
Checkpoints
Checkpoints can be referred to as security gates, the authentication process has to successfully pass through every single gate defined in order to be granted access.
By default, when logging in, checks for existing sessions
and failed logins
occur, you may configure an indefinite number of "checkpoints".
These are classes which may respond to each event and handle accordingly. We ship with two, an activation
checkpoint and a throttle
checkpoint.
Note Checkpoints must implement
Cartalyst\Sentinel\Checkpoints\CheckpointInterface
.
Feel free to add, remove or re-order these.
Activation
The activation
checkpoint is responsible for validating the login attempt against the activation checkpoint to make sure the user is activated prior to granting access to a specific area.
Throttle
The throttle
checkpoint is responsible for validating the login attempts against the defined throttling rules.

Hashing
By default, Sentinel encourages the sole use of the native PHP 5.5+ hashing standard, password_hash()
. Sentinel requires no configuration to use this method.
While it is not encouraged for security reasons, we provide functionality to override the hashing strategy used by Sentinel so as to accomodate for legacy applications moving forward.
There are 5 built in hashers:
Native Hasher
The encouraged hasher to use in Sentinel is the native hasher. It will use PHP 5.5 or newer's password_hash()
function and is setup to use the most secure hashing strategy of the day (which is current bcrypt). There is no setup required for this hasher.
Bcrypt Hasher
The Bcrypt hasher uses the Bcrypt hashing algorithm. It is a safe algorithm to use, however this hasher has been deprecated in favor of the native hasher as it provides a uniform API to whatever the chosen hashing strategy of the day is.
To use the Bcrypt hasher:
// Native PHP
$sentinel->setHasher(new Cartalyst\Sentinel\Hashing\BcryptHasher);
// In Laravel
Sentinel::setHasher(new Cartalyst\Sentinel\Hashing\BcryptHasher);
Callback Hasher
The callback hasher is a strategy which allows you to define the methods used to hash a value and in-turn check the hashed value. This is particularly useful when upgrading from legacy systems, which may use one or more hashing strategies. It will allow you to write logic that accounts for old strategies and new strategies, as seen in the example below.
Be extremely careful that you don't expose vulnerabilities in your system by designing a hashing strategy that is unsafe to use.
To use the callback hasher:
$hasher = function($value)
{
return password_hash($value, PASSWORD_DEFAULT);
};
$checker = function($value, $hashedValue)
{
// Try use the safe password_hash() function first, as all newly hashed passwords will use this
if (password_verify($value, $hashedValue))
{
return true;
}
// Because we're upgrading from a legacy system, we'll check if the hash is an old one and therefore allow us to log the person in anyway
return some_method_to_check_a_hash($value, $hashedValue);
}
// Native PHP
$sentinel->setHasher(new Cartalyst\Sentinel\Hashing\CallbackHasher($hasher, $checker));
// In Laravel
Sentinel::setHasher(new Cartalyst\Sentinel\Hashing\CallbackHasher($hasher, $checker));
Other Hashers
Other hashers, such as the whirlpool hasher and the SHA256 hasher are supported by Sentinel, however we do not encourage their use as these algorithms are open to vulnerabilities. We would encourage people to use the callback hasher and implement their own logic for moving away from such systems.
We understand that not every system needs to move away from these strategies however. Telling Sentinel to use these strategies is straight forward:
// Native PHP
$sentinel->setHasher(new Cartalyst\Sentinel\Hashing\WhirlpoolHasher);
$sentinel->setHasher(new Cartalyst\Sentinel\Hashing\Sha256Hasher);
// In Laravel
Sentinel::setHasher(new Cartalyst\Sentinel\Hashing\WhirlpoolHasher);
Sentinel::setHasher(new Cartalyst\Sentinel\Hashing\Sha256Hasher);
