If you want to improve security on your store, then you can activate SSL certificates in your Shopify admin. SSL certificates encrypt your store's content and publish it securely using HTTPS instead of HTTP.
For example, if your store's URL is
http://www.example.com, it will be updated to
https://www.example.com after you activate SSL certificates. Customers who use the original URL will be redirected to the encrypted online store.
Having SSL certificates on your online store lets you:
- add a new layer of security to your online store by using HTTPS instead of HTTP
- build customer trust by displaying the SSL padlock icon beside your online store's URL:
If your online store displays content (including images, videos, or webfonts) that's hosted somewhere other than Shopify, then you can verify it on the Domains settings page in your Shopify admin to make sure it doesn't invalidate your SSL certificate.
Best practices for SSL content
There are a few things you can do to make sure your online store's content stays secure:
- host all of your online store's content on Shopify or a server that publishes over HTTPS (learn about uploading files to your Shopify admin)
- host your video content on a service that publishes over HTTPS
- if you're using webfonts, make sure they're published over HTTPS from their source.
HTTP Strict Transport Security (HSTS) is a mechanism that forces browsers to access a website with an HTTPS connection only. Using a secure connection in this way prevents certain kinds of network attacks, which helps ensure the safety of your information and your customers' information.
An HSTS policy can be set on a domain for a fixed length of time. Shopify's default length is 90 days.
If you remove a domain or leave Shopify entirely, then this policy will remain in effect on the domain for a further three months, but you won't need to take any additional steps as long as you move the domain to another platform that uses HTTPS.
If you move the domain to a platform that doesn't use HTTPS, then for the next three months after removing the domain from Shopify, anyone attempting to access the site will see an error message in their browser that says the site is not trusted or the certificate is not valid.
