Thanks for sharing your question with the Klaviyo Community!
The Klaviyo app via the Shopify App Store is meant as a first time registration and not meant as a login portal for Klaviyo.
Instead, we recommend logging into your Klaviyo account by navigating to Klaviyo.com and logging in with the credentials you originally created. In the event you used the Klaviyo app via the Shopify App Store and registered a second time, this may indicate that you created another Klaviyo account that you may have linked to your Shopify store. If this has occurred, I would recommend following the instructions found in the below Community post on how to uninstall this accidentally created Klaviyo account with your Shopify store.
