    'users' => [
        'driver' => 'our_provider',
    ],
],

AuthServiceProvider.php

<?php

namespace App\Authentication;

use Auth;
use App\Authentication\UserProvider;
use Illuminate\Support\ServiceProvider;

class AuthServiceProvider extends ServiceProvider
{
    /**
     * Perform post-registration booting of services.
     *
     * @return void
     */
    public function boot()
    {
        Auth::provider('our_provider', function($app, array $config) {
            return new UserProvider();
        });
    }

    /**
     * Register bindings in the container.
     *
     * @return void
     */
    public function register()
    {
        //
    }
}

User.php

<?php

namespace App\Authentication;

use Illuminate\Contracts\Auth\Authenticatable;

class User implements Authenticatable
{
    /**
     * @return string
     */
    public function getAuthIdentifierName()
    {
        // Return the name of unique identifier for the user (e.g. "id")
    }

    /**
     * @return mixed
     */
    public function getAuthIdentifier()
    {
        // Return the unique identifier for the user (e.g. their ID, 123)
    }

    /**
     * @return string
     */
    public function getAuthPassword()
    {
        // Returns the (hashed) password for the user
    }

    /**
     * @return string
     */
    public function getRememberToken()
    {
        // Return the token used for the "remember me" functionality
    }

    /**
     * @param  string  $value
     * @return void
     */
    public function setRememberToken($value)
    {
        // Save a new token user for the "remember me" functionality
    }

    /**
     * @return string
     */
    public function getRememberTokenName()
    {
        // Return the name of the column / attribute used to store the "remember me" token
    }
}

UserProvider.php

<?php

namespace App\Authentication;

use Illuminate\Contracts\Auth\UserProvider as IlluminateUserProvider;

class UserProvider implements IlluminateUserProvider
{
    /**
     * @param  mixed  $identifier
     * @return \Illuminate\Contracts\Auth\Authenticatable|null
     */
    public function retrieveById($identifier)
    {
        // Get and return a user by their unique identifier
    }

    /**
     * @param  mixed   $identifier
     * @param  string  $token
     * @return \Illuminate\Contracts\Auth\Authenticatable|null
     */
    public function retrieveByToken($identifier, $token)
    {
        // Get and return a user by their unique identifier and "remember me" token
    }

    /**
     * @param  \Illuminate\Contracts\Auth\Authenticatable  $user
     * @param  string  $token
     * @return void
     */
    public function updateRememberToken(Authenticatable $user, $token)
    {
        // Save the given "remember me" token for the given user
    }

    /**
     * Retrieve a user by the given credentials.
     *
     * @param  array  $credentials
     * @return \Illuminate\Contracts\Auth\Authenticatable|null
     */
    public function retrieveByCredentials(array $credentials)
    {
        // Get and return a user by looking up the given credentials
    }

    /**
     * Validate a user against the given credentials.
     *
     * @param  \Illuminate\Contracts\Auth\Authenticatable  $user
     * @param  array  $credentials
     * @return bool
     */
    public function validateCredentials(Authenticatable $user, array $credentials)
    {
        // Check that given credentials belong to the given user
    }

}

Declaration of App\Authentication\UserProvider::updateRememberToken(App\Authentication\Authenticatable $user, $token) must be compatible with Illuminate\Contracts\Auth\UserProvider::updateRememberToken(Illuminate\Contracts\Auth\Authenticatable $user, $token)

I fixed it by adding this line:

use Illuminate\Contracts\Auth\Authenticatable;
