Passwordless login allows your customers to easily login to their customer portal using a 4-digit authentication code sent via SMS or email (both if your customers have a phone number on file). If you’re on Shopify Plus, Multipass will allow your customers to be logged into both their Recharge customer portal and Shopify account.

This feature makes it easier for your customers to manage their subscription, reducing customer churn and customer support tickets.
