Point of Sale staff management
When you have staff who help you sell in person, you need to give those staff permissions so that they can use Shopify POS to run your store.
Shopify POS staff with admin permissions need to be given access to Shopify POS by selecting the Access Point of Sale permission on the Users and permissions page in the Settings section of your Shopify admin. You can also have POS only staff who don't have admin permissions and who need a PIN to login to Shopify POS.
To set up the Shopify POS app using a Shopify account or login credentials, staff must have the Shopify POS login requirements. If staff don't have the Shopify POS login requirements, then they can only use a PIN to access the Shopify POS app after staff who have the requirements have logged in first.
You can give different staff different permission levels to your store's Point of Sale (POS) and retail activities using POS roles, which are a set of permissions. You can create different POS roles that, when assigned to your POS staff, determine how much permission each staff has to the various activities that are required to run your store.
