Issue with Customer Login Method on Horizon Theme + Additional Question

Shopify Discussion

Topic summary

A user building a Shopify store with the Horizon theme is unable to switch from email code login to traditional email/password authentication, despite changing the settings. The storefront continues to show only the one-time code option.

Key Finding:

  • The Horizon theme exclusively supports Shopify’s new customer account system (email code login)
  • To use legacy email/password login, a different theme is required
  • The issue is not related to the custom domain

Regarding Loyalty Programs:
The new customer account system (email code) is compatible with loyalty points and discount features. Most apps support this authentication method, though compatibility should be verified with specific app developers.

Resolution Status: The user must choose between keeping the Horizon theme with email code login or switching themes to enable traditional password-based authentication.

Dear Support Team,

I am currently in the process of building my new Shopify store using the Horizon theme. I wanted to change the customer login method from “login via email code” to the classic email and password registration, which I selected in the settings.

However, after making this change, the login behavior remains the same—customers are still only able to log in using the one-time code sent to their email. There seems to be no visible change on the storefront.

I have tried looking into modifying the theme’s code to resolve this, but unfortunately, I don’t have the technical knowledge to do it properly, and my attempts haven’t been successful. Could this issue possibly be related to the custom domain I recently purchased and connected to my store? I would really appreciate any assistance or guidance on how to make this change work correctly.

Additionally, I’d like to ask: if I decide to keep the “login via email code” method, will I still be able to implement features such as loyalty points programs and discount codes for individual customers?

Thank you in advance for your support.

Best regards,
Peter

Hi @Peter_PL,

You can refer link.
You just need to select the option ‘Legacy customer accounts’ for it, it will help you change your login with email and password.
If I helped you, then a Like would be truly appreciated.

Hey @Peter_PL :waving_hand:

Shopify’s new Horizon themes specifically only support the new customer accounts option (login via emailed code), to use the legacy customer accounts type (login with email and password) you would need to use a different theme.

A lot of apps are compatible with the new customer accounts type, if you already have one you are using you would need to check with them directly, but otherwise you should definitely be able to find loyalty and discount apps that are compatible.
