在laravel5.4中保护api路由的最简单方法是什么？

Now, I am using Laravel Passport(4.0) in my project

But it's not working well in production environment.

I was thinking to stop using Laravel Passport.

Is there any way easier than using Laravel Passport?

I always prefer to use token based security to protect my APIs. Use JWT(Json Web Tokens). Learn more about it - https://jwt.io/
