Gatehouse — SSO Login Hub

Your B2B buyers already have accounts in Okta, Microsoft Entra ID, Auth0, or another OpenID Connect provider. Gatehouse lets them sign in to your store with those, while retail shoppers get Google or a one-time email code. Shopify customer accounts accept one identity provider: Gatehouse fills it, then gives each customer group its own sign-in page, methods, and branding, linked from your store. Staff can log in as any customer, fully audited. Requires Shopify Plus and new customer accounts.
