Basic general information

MC: Authentication via OTP and Passkey — the first and only CS-Cart add-on that enables users to log in using biometrics (Face ID, Touch ID, Windows Hello) and one-time codes (OTP) via SMS or email.

Efficiency for the store

This add-on improves login conversion by simplifying authentication:

- Passwordless login via Passkey (Face ID, Touch ID, Windows Hello).
- Auto-filling of OTP codes from SMS/email for faster authentication.
- Flexible email notification settings through the standard CS-Cart notification system.

The add-on reduces login failures, enhances security, and makes the process more convenient for users

How the product works

The add-on operates by generating one-time passwords (OTP) and supporting Passkey authentication. After entering a phone number or email, the user receives a code that is automatically inserted into the input field if supported by their device.

Important: The add-on does not have built-in integrations with SMS gateways. It only generates OTP codes, while the actual message delivery is handled by third-party add-ons integrated with SMS providers. This allows store owners to use their existing SMS solutions.

Trial Version

Trial version provides you an add-on with full set of features for the period from 3 days to month in depence on condition of the specific vendor. The add-on will be disabled when the trial perod is expired. In case the add-on has a free version, when the trial period is expired, the add-on functionality will be limited in accordance with abilities of the free version. Purchase a subscribtion to the add-on in order to restore the full functionality of the add-on.

Freemium Version

Not available

Free version provides you an ability to use the add-on permanently on special condition. Technical support and individual customization services are not available and the add-on functionality, abilities and adaptation to new cs-cart versions are heavily limited. Purchase the add-on subscription or the lifetime version to get the fully functional add-on version.

By subscription

Not available

By purchasing the subscription to the add-on you get the latest version of the add-on. Full functionality of the add-on, its future updates, individual customization and limited amount of free technical support service are available during the subscription period. When the subscription period is expired, the add-on will be disabled on your store. In case the add-on has a “Free Version”, the add-on won’t be disabled but most of its features, technical support services and many other advantages will no longer be available.

Lifetime Version

Available

This subscription type provides a permanent, fully functional version of the add-on. You won’t have to bother with prolongation of subscription, and technical support service will be unlimited for you. Basically, this subscription type is demanded, in case the fully functional add-on version has been previously used, and you have made a certain conclusions about its purpose and efficiency.
