Laravel 5.6 - Store PassPort keys

I am using Passport in a Laravel 5.6 project and all is working great in my local environment.

However, when I deploy it to Amazon I have to run the following to generate the client and secrets.

php artisan passport:install

This works, but it means the keys change everytime I deploy a new version. Is there a way to keep the same keys?

Can they be stored somewhere?
