Laravel Passport - which grant to use for my users apps?

I have application where users can register and add their own applications (websites, mobile applications).

For each of these applications, I want to give access to my API and allow to get products form my database.

For example: User X signup in my app, adds his blog user-X-blog.com and get access token. Next he can call to my API and get some products to show on his blog post.

Which grant should I implement to make my API based on Laravel Passport safe and useful (each user application with its own token, no user login required to make api call, long-lived tokens)?

Is it good idea to create for each user apps dedicated client and use client credentials grant? It doesn't look very safe for me (or maybe I'm wrong).
