SSO for external brand store users

How:
Add OpendId Connect based SSO support for Brand Store. That would makes it easy to integrate Brand store with other applications that also use OpendId Connect based SSO (implemented e.g. via auth0)

Why:
Brand store provides lot of out of the box functionalities that would make it a good solution to be used as part of external product data portal or a similar solution, but the user experience is poor if SSO is not supported.

There already exists product idea about Brand store SSO for internal PIM users, but e.g. in our customer case there would be lot of users that shall have access only Brand Store but not to other parts of Inriver PIM.

If/when there is already SSO implemented for the product data portal (or similar solution), it would be beneficial if also Brand store supported SSO for the same users .

For Who:
Anyone who wants to allow SSO for Brand store without adding the same users in Inriver PIM.

Impact:
This is a key requirement from our customer.

Additional context:
We have communicated this need already earlier to Inriver. There is a similar request https://partnercommunity.ideas.aha.io/ideas/INSE-I-175 but it was considered for internal PIM users so we were asked to add a new idea for external brand store used.

Please, add your suggestion and feedback above to add to the insights used by Product team when deciding priorities and direction of the Inriver PIM.
