2 Laravel中具有不同身份验证过程的用户模型

I'm working with an app that has an Backend API for mobile and Web Login for Administrators. The authentication of Backend API was jwt-auth 0.5.* and for my Administrators I used the session driver.

This is the default of auth:

'defaults' => [
    'guard' => 'web',
    'passwords' => 'users',
],

'web' => [
    'driver' => 'session',
    'provider' => 'users',
],

 'admin' => [
    'driver' => 'session',
    'provider' => 'admins',
],

The Backend API Authentication works but the Web Admin Authentication doesn't save the session of the logged in administrator. By the way I created a guard for administrators.

How can I handle this situation?
