CNXK ‑ SSO

CNXK, officially listed on the Shopify App Store as CNXK ‑ SSO, is a Shopify app in the Accounts and login category.

It supports custom IDP integration and multiple social login options in one setup, so merchants can offer a smoother sign-in experience without building and maintaining their own authentication flow. It is useful for stores that need external identity systems, easier customer account access, or simplified social account connection and login management.

CNXK offers a free plan and 3 paid plans starting at $19/month and going up to $149/month. The paid plans unlock advanced features beyond what's available on the free tier.
