Linking a CTA to automatically log a customer into their Shopify account

Hi @Madelena V, welcome to the community!

As far as I know, Shopify doesn’t let you generate an access token to log in a user from a link.  I think they restrict this for security purposes.  There are some third party tools that manages single-signon or “multipass” which may allow some capabilities of a “login url” (with some expiration time) - but those are for really advanced Shopify Plus sites that require more complex user management systems.  

I think you can direct people to the “My Account” page on your site, and if they are currently logged in on their browser (or device), they should go right to that page.  If they need to log in, Shopify will present the login page to them. 

If you really want to simplify the login process, you can also make it easier for your users to login with other methods of authentication such as Shopify’s Shop Pay or other third party logins (Google, Facebook/Meta, etc).  Some of that implementation does require developer resources, or a Shopify App or other tools to be installed.

If anyone knows other ways to simplify login (or to get to their “My Account” page in Shopify), chime in!
