To protect your Shopify store from being hacked, secure the parts Shopify doesn't control: your owner login and the email behind it, staff and collaborator access, the apps you install, your theme code, and your domain. Shopify runs the servers, the SSL certificates and a PCI DSS Level 1 compliant checkout. Almost every store compromise starts with one of those five areas instead.

October 2026 showed this clearly. Between October 10 and 14, attackers sent shoppers at a number of Shopify stores to fake checkout pages. They never broke into Shopify. They broke into the tools behind a few third party apps and pushed their own code into stores through those apps. We covered the full timeline in Was Shopify Hacked? The October 2026 Checkout Hijack.

It wasn't the first time the risk came from people and tools around a store. In September 2020, Shopify disclosed that two members of its own support team had taken customer transaction records from fewer than 200 merchants. Shopify's systems weren't breached either time. The access came through people and tools that stores trusted.

That pattern shows up far beyond Shopify. The 2026 Data Breach Investigations Report found a third party involved in 48% of breaches, and credential abuse somewhere in the attack chain of 39%. For a Shopify store, "third party" usually means an app, a freelancer or an agency, and "credentials" means somebody's login.

Here's how to close each of those doors.

What Shopify Protects and What Falls to You

Shopify secures the platform. You secure who and what gets access to your store.

1. Lock Down the Owner Account

The owner account can change payouts, add staff, install apps and edit code. Treat it like the keys to your bank account.

• Set up a passkey. Shopify supports passkeys that use your fingerprint, face or device PIN. There's no password to steal or phish.
• Turn on two step authentication with an authenticator app or a physical security key. Shopify no longer lets you add SMS as a new method. If you use Shopify Payments, two step authentication is required, and turning it off can put your payouts on hold.
• Save your recovery codes during setup, somewhere offline. They're how you get back in if you lose your phone.
• Use a unique password stored in a password manager. If your Shopify password matches one leaked from another site, Shopify may lock the account until you reset it.
• Never share the owner login. Shopify Support will never ask for your password. Anyone who needs access gets their own account.

2. Secure the Email Behind Your Store

Every Shopify password reset goes to your email. If someone controls that inbox, two step authentication on Shopify only slows them down.

• Give the email account its own strong password and two step authentication.
• Remove any old forwarding rules or filters that send Shopify emails to trash or spam. Attackers sometimes add these so you never see security alerts.
• Use a dedicated address for the store owner account, not a shared team inbox.

3. Give Staff and Collaborators Only What They Need

Every login in your store is a door. Most stores have more open doors than they realize: a former VA, an agency from two redesigns ago, a freelancer who fixed one bug in 2023.

• Review users under Settings, then Users (or Users and permissions). Filter by collaborators to see every outside account.
• Grant permissions by job. A customer service rep needs orders and customers, not themes, apps or payouts.
• Protect collaborator access with your four digit collaborator request code in the Security tab. Only partners you give that code to can request access. Click "Generate new code" after a project ends so old codes stop working.
• Remove access the day someone leaves. Shopify expires collaborator access after 90 days without a login, but staff accounts stay open until you close them.

4. Vet Every App Before You Install It

Apps are the most common way new code gets into a Shopify store, and October 2026 showed what happens when an app developer's own tools are compromised. You can't audit a developer's servers, but you can control how many apps you trust and what they can touch.

• Read the permissions screen at install. A size chart app has no reason to ask for access to customer data or orders.
• Check the developer, not only the star rating. Look at how long they've been listed, how recently they've updated, and how they answer complaints in reviews.
• Remove apps you no longer use, then delete the code and app embeds they leave behind in your theme. Uninstalling doesn't always clean up everything.
• Prefer fewer apps that do more. Every app you drop is one less company that can push code to your storefront. Your pages usually load faster too, which is the same work behind our Shopify speed optimization.

Apps that run code on your checkout path need closer controls. We'll cover those in our next guide on stopping checkout hijacks.

5. Control Who Edits Your Theme Code

• Duplicate your live theme before any edit and name it with the date. If something breaks or looks wrong, you can publish the copy in minutes.
• Edit code only on an unpublished copy, and publish after you've reviewed it.
• Only let people you've vetted edit code. Pasting a script from a forum or an unknown freelancer into theme.liquid is how many stores end up with code nobody can explain.
• Export your products, customers and orders as CSV files on a regular schedule, so a bad edit or a rogue account doesn't cost you days of rebuilding.

If your theme has been patched by several developers over the years and nobody knows what all the code does, a clean rebuild is often safer than another round of fixes. That's where a Shopify store redesign makes sense.

6. Protect Your Domain and Customer Emails

If someone takes over your domain, they can point your store's address anywhere. If your email isn't authenticated, scammers can send messages that look like they came from your store.

• Turn on two step authentication and a transfer lock at your domain registrar.
• Authenticate your sender email in Shopify's notification settings, so Shopify adds the DNS records that prove your emails are real.
• Set up SPF, DKIM and DMARC records. They make it much harder for anyone to send fake order or refund emails in your name.

7. Train Your Team to Spot Phishing

Many store takeovers start with an email. Fake "Shopify" messages asking merchants to update payment details, verify a store or review a policy violation have circulated for years.

• Check the sender's domain and every link before clicking. Real Shopify emails come from shopify.com addresses.
• Log in by typing admin.shopify.com yourself, never through an email link.
• Report suspicious messages to Shopify, and tell your team when one shows up so nobody else clicks it.

8. Watch for Warning Signs

Shopify gives you the tools to spot trouble early. Few store owners look at them.

• Read every "new device has logged in" email. If it wasn't you, click "No, secure account" right away.
• Check the activity log at shopify.com/admin/activity for changes nobody on your team made.
• Look for unfamiliar staff accounts, apps, discounts or payout details. These are common signs that someone else has access.
• Use Shopify Flow to flag high risk orders automatically, so fraud attempts don't slip through on busy days.

Your Monthly Shopify Security Routine

Set a recurring 20 minute calendar reminder and work through this list.

Monthly Security Checklist

Confirm two step authentication is on for every staff account, not only the owner.

• Review users and collaborators. Remove anyone who no longer works with you.
• Review installed apps. Remove anything unused and clean up its leftover code.
• Scan the activity log for changes nobody on your team made.
• Check payout details, store contact email and domain settings.
• Duplicate your live theme and export products, customers and orders.
• Generate a new collaborator request code if any outside project ended.
