mobile app authentication explanation

[Antonio84]

Hello, it is not clear to me the authentication on storefront.

I need to build a public shopify mobile app which access the storefront api. 

The customer can install the app in their mobile phone and buy products, register and so on.

The documentation says the merchant need to install this app to request the access token.

Is the access token obtained after the merchant installation unique and used by all the customers that install the app in their phone or should the app request a token for each customer?

The access token is used to access the Storefront API and that's it. Customers don't care if you authenticate them with a token or not.
