Set staff permissions for Shopify POS
Staff created in the Shopify admin can log into Shopify POS using their own credentials only if they have the required permissions. To give staff access to Shopify POS, go to the Settings > Plan and permissions page in your Shopify admin, and then select Give Point of Sale access to this staff.
Shopify staff that are created in the Shopify admin need the Shopify POS login requirements to log into Shopify POS. If staff doesn't have all the required permissions, then they can only use a PIN to log in after a staff that has the required permissions has logged in first.
If you're the store owner, or have the Manage Settings permission, then you can change staff permissions in your Shopify admin.
