Cart2Cart migrates Summer Cart customer accounts, but does not migrate usable login passwords for Summer Cart. After migration to another platform, customers must use “Forgot password” (or an invite/reset flow) on the target store.

Summer Cart password migration (current)

1. Summer Cart stores customer and admin passwords as one-way salted hashes (Summer Cart documents a salted HMAC-SHA1 approach). Hashes cannot be reversed to the original password.

2. Cart2Cart’s free Migrate customers’ passwords option applies only to selected cart pairs that share compatible hashing (and often require a Cart2Cart password plugin on Magento, WooCommerce, PrestaShop, OpenCart, or thirty bees). Summer Cart is not in that supported set.

3. Plan a customer communication: announce the storefront change and include reset-password instructions before go-live.

4. Optional: send a post-migration welcome email with a password-reset link, and/or offer a small first-login discount to encourage reactivation.

Earlier general explanation (legacy)

Password hashing is one-way. Different shopping carts use different salts and algorithms, so a hash from Summer Cart generally cannot authenticate a customer on another platform. Cart2Cart can move customer records; customers then create a new password on the target store.
