Submit a job at login when Sanctum token is issued

You can add a listener on your EventsServiceProvider that listens to this event: Illuminate\Auth\Events\Login

A listener to the exact same event to save the last login timestamp in one of my projects:

<?php

namespace App\Providers;

use App\Auth\Listeners\UpdateLoginInfoListener;
use Illuminate\Auth\Events\Login;
use Illuminate\Foundation\Support\Providers\EventServiceProvider as ServiceProvider;

class EventServiceProvider extends ServiceProvider
{
    /**
     * The event listener mappings for the application.
     *
     * @var array<class-string, array<int, class-string>>
     */
    protected $listen = [
        Login::class => [UpdateLoginInfoListener::class],
    ];

    /**
     * Register any events for your application.
     *
     * @return void
     */
    public function boot()
    {
    }
}

If you are not familiar with event listener, please look the docs about it:
