What it does

Sign in with Apple adds a Continue with Apple button to the sign-in pop-up, sign-in page, checkout and registration page of CS-Cart and Multi-Vendor. Customers who use Hide My Email get an account on their private relay address, the name Apple sends once is saved, and the connected Apple ID shows in the profile. Vendors can sign in to the vendor panel. It is the Apple part of Social Login Pro as a separate add-on.

How it works

In your Apple Developer account create a Services ID with your domain and the redirect URI, and a Sign in with Apple key. On Customers, Apple sign-in enter the Services ID, Team ID, Key ID and the .p8 key and switch it on. Customers click the button, confirm with Face ID or their Apple ID password and come back signed in. Security: Apple's form post with state and nonce, verified ID tokens, browser binding, encrypted key.

Features

  • Continue with Apple button in the sign-in pop-up, sign-in page, checkout and registration page
  • Client secret signed with your .p8 key for each sign-in (ES256), so it never expires
  • Hide My Email relay addresses supported; the name sent on the first sign-in is saved
  • Verified Apple ID tokens (signature, issuer, audience, expiry, nonce)
  • Safe account matching: confirmed e-mail, or the account password asked once
  • Connected Apple ID in the customer profile, with disconnect
  • Vendor panel sign-in with Apple (Multi-Vendor)
  • Statistics: sign-ins, new accounts and failure reasons per day
  • Black, outline or icon-only button in three shapes
  • Moves up to Social Login Pro without reconnecting customers (keys and connections are imported)
  • Full page cache friendly; CS-Cart, CS-Cart Ultimate and Multi-Vendor, 4.17.2 to 4.21
