WHMCS Single Sign-On (SSO) with Magento enables secure login access into Magento using WHMCS as OAuth and OpenID Connect provider. Magento OAuth/OpenID Connect Single Sign-On module gives the ability to enable OAuth/OpenID Single Sign-On for Magento. If you want users to log in to your Magento site using their WHMCS credentials, you can simply do it using our Magento OAuth/OpenID Connect Single Sign-On Plugin. Once you configure the WHMCS with the Magento module, you can allow users to SSO to your Magento site using WHMCS. It has powerful Single Sign-On (SSO) features like user profile attribute mapping and role mapping, among others.
