Optimize Laravel login time expiration policy to improve system security

Title: Optimizing Laravel login time expiration policy and improving system security

In web development, the user login function is one of the basic functions. In order to ensure the security of the system, the login time expiration policy is particularly important. When developing using the Laravel framework, we can further improve the security of the system by optimizing the login time expiration policy. This article will introduce how to optimize the login time expiration strategy in Laravel and provide specific code examples.

1. Default login expiration time setting

In Laravel, user login status will be maintained for 2 weeks by default (1209600 seconds). This means that after logging in, users can stay logged in for 2 weeks without re-entering their username and password. However, for some sensitive operations or systems with high security requirements, this default setting may not be secure enough. Therefore, we can set a shorter login expiration time by modifying the configuration file.

2. Set the login expiration time

Open the configsession.php configuration file, find the lifetime parameter in the file, and modify its value to ours The required login expiration time. For example, we set the login expiration time to 1 hour (3600 seconds):

'lifetime' => 3600,

3. Active logout

In addition to setting a shorter login expiration time, we can also actively log out ways to improve system security. For example, when a user performs some sensitive operations, we can proactively ask the user to log out and require them to re-enter their user name and password.

In Laravel, we can use the following code to actively log out the user login status:

Auth::logout();

4. Use single sign-on

In order to strengthen the security of the system, we also Consider using a single sign-on mechanism. With single sign-on, users only need to log in once and can use it in multiple related systems without having to log in repeatedly. This can reduce the number of users forgetting to log out and improve the security of the system.

You can use Passport in Laravel to achieve single sign-on. First install the Passport package:

composer require laravel/passport

Then run the php artisan passport:install command to install Passport. Finally, register the Passport route in AuthServiceProvider:

use LaravelPassportPassport;

Passport::routes();

5. Custom login failure processing

Sometimes, the system may need to perform some custom processing of login failure , such as jumping to a specific page or recording a log. In Laravel, we can achieve this function through custom middleware.

First, create a middleware named CustomSessionTimeoutRedirect:

php artisan make:middleware CustomSessionTimeoutRedirect

Then, implement custom processing in the handle method of the middleware Logic:

public function handle($request, Closure $next)
{
    if (Auth::check() && time() - strtotime(auth()->user()->updated_at) > config('session.lifetime')) {
        Auth::logout();
        return redirect()->route('login')->with('session_timeout', '登录已失效，请重新登录');
    }

    return $next($request);
}

Finally, register the middleware in Kernel.php, which can be used in global middleware or routing middleware:

'custom.session.timeout' => AppHttpMiddlewareCustomSessionTimeoutRedirect::class,

Conclusion

By optimizing the login time expiration policy, we can further improve the security of the system. In this article, we explain how to set a shorter login expiration time, proactively log out, use single sign-on, and customize login expiration handling. It is hoped that these methods can help developers improve system security and protect users' account information.
