How to Associate a Storefront to a Consumer Group

By associating a consumer group with a storefront, you indicate that the storefront is not available for public viewing and should only be available to the users in your consumer group. All consumers will first see a login view on any storefront associated with a consumer group.

Let's take a look at the steps to make a storefront "private" by adding a consumer group.

Select "Marketplaces" from the left-hand Quivers menu.
Click on Storefrontsin the sub-menu of "Marketplaces" on the left-hand side of the panel.
Once in the storefront editor, select the “Consumer Groups” tab.
On this page, you will find the option Enable Private Access. Consumers mapped under this will be able to view and purchase products on this storefront.
Using the checkboxes next to each consumer group, select which groups should have access to this storefront and then click on Save.
