This app Says that a free plan is available, but the app has a 3 dollar charge waiting for you in 30 days.

A simple and excellent app, very reasonably priced for the value. In my opinion, a must-have. We migrated to Shopify from a different eCommerce platform and imported around 2000 users. Shopify natively tells these users that they do not have an account when they return to the new site, which would be frustrating and alienating for my customers to say the least. Passwordless Social Login took care of our problem in a snap and takes the frustration out of the login, signup, and password management process so that customers can focus on buying products and not on the login process. The future is now. Do yourself a favor and use this app.

Passwordless login made account creation on Shopify a very slick experience. Keith and team have been super helpful in customizing the experience and integrating into the social/community features.

Highly recommend Passwordless as a gateway for deeper engagement with your customers.
