Enable Single Sign On (SSO) for ecommerce site logins

As ProspectSoft is now enabling us to use Single Sign On (SSO) to access the CRM etc it would be great if we could also offer this to customers accessing our ecommerce sites and their accounts - as Prospectsoft says "If you aren't using single sign on (SSO), then you definitely should be! Whether you want to use the new Access login, your Xero login, an Office 365 or Google login - SSO is faster, more convenient and more secure. In fact, the best option is to head to the domains configuration and enforce SSO for all your users via an identity system that all your users have (typically Office 365 or GSuite)."

So why not let us offer the same benefits to our customers?
