Can i get posts, or create new posts with Laravel Airlock tokens, or for create or updated any rows in database i need use Laravel Passport?
Take a look at this great post : https://divinglaravel.com/authentication-and-laravel-airlock
The last part gives you the answer as well :) but please read it fully, it will clear things up for you.
and yes, you can use Airlock only not need to Passport
