I'm sorry to hear that you were unable to login to your store. If you're seeing an error message that says It looks like you don't have access to this store. Contact the store administrator for access., but you have been able to login previously, I recommend following these troubleshooting steps:
clear your browser's cache and cookies
check for browser updates
try an incognito browsing window or test another browser
Let me know if any of these troubleshooting steps resolve the issue for you. If you've tried all of these steps and still cannot login, please contact our team via the Shopify Help Center.
