Laravel Tinker: login as another user and generate an injectable session cookie

Generating session cookie

• Enter Laravel Tinker
  

php artisan tinker

• Authenticate
  

# Login using id
auth()->loginUsingId(1);

# Login using a user instance
auth()->login(User::where('email', 'foo@bar.com')->first())

• Save the session
  

session()->save()

If you are not using EncryptedCookie for some reason, you can stop at this step and proceed to injecting the session id to your session cookie:

session()->getId()

• Generate the cookie value that is about to get encrypted
  

\Illuminate\Cookie\CookieValuePrefix::create(config('session.cookie'), app(\Illuminate\Contracts\Encryption\Encrypter::class)->getKey()).session()->getId()

• Generate the encrypted cookie value

It is highly likely the 2nd parameter here is …

auth authenticate can com cookie email instance laravel login php session
