Can an existing SSO provider connect to an online store without issues?

[Patrixio1990]

Hey guy.

If anyone can help us with this question. Thank you so much.

The Setup

We'll be opening an online store via Shopify but, instead of an online store where everyone can shop, our store will be exclusively used by this company (bank) as an internal store. Meaning no other customers outside their company.

Since this client is a bank and employee information is sensitive, they want to use their own SSO provider so that they can access our store using their existing company username & password.

The Question

Can Shopify connect to an existing SSO without having any problem?

If yes, do I need a Shopify Plus account, or will it work for non plus accounts?

Do I have to use Shopify Apps?

Hope someone can enlighten us with this question.

Thank you so much
