Squarespace offers free SSL certificates for all Squarespace Domains and third-party domains connected to a site. With SSL enabled automatically, your visitors can access a constant, secure connection on every page of your site. Through SSL, your visitors see a lock icon next to your URL in the browser, showing that their information is safe.
Use the Security & SSL panel to customize your settings, and follow this guide to learn how to ensure a secure connection throughout your site.
Note: If you're currently using a third-party SSL provider, like CloudFlare, you can switch to Squarespace's certificate. See the FAQ below for details.
Note: We don’t offer the ability to install custom SSL certificates at this time.
What is SSL?
Secure Sockets Layer, or SSL, is a technology that secures the connection between your browser and the website you’re visiting. To verify that SSL is protecting a page, look for a URL beginning with https://, instead of http://, and a green, closed padlock icon. This allows visitors to navigate the website and submit information through a secure connection.
SSL provides three important security benefits:
- Privacy: Encrypts the connection between the browser and web server and securely transmits information (like login credentials) to prevent unauthorized parties from eavesdropping.
- Data integrity: Prevents unauthorized parties from altering data during transmission (like during a Form Block submission).
- Authentication: Protects against impersonation by requiring web server proof of identity.
Enabling SSL may help your site load faster, as Squarespace uses HTTP/2 for SSL-enabled sites. It may also help more visitors find your site: in 2014, Google announced that SSL-secured websites would potentially enjoy a rankings boost in their search results.
How Squarespace uses SSL
If you have custom domains linked to your Squarespace site, we automatically generate an SSL certificate for your site. This allows visitors to view your site over an HTTPS connection. This is automatically included for Squarespace Domains and third-party domains.
If you’re using a third-party domain, ensure that it’s correctly connected to your site to allow a secure SSL connection. Specifically, confirm that you’re using our required CNAME records and A records and that the domain points to Squarespace.
When your site loads with SSL protection enabled, you’ll see a lock icon and https:// next to the URL in the browser bar:
Your site includes two SSL-related security settings, depending on what you need:
- Secure (Preferred) - All visitors are redirected to HTTPS, even if they entered the HTTP version in their browser. Sitemaps contain HTTPS links and search engines index the HTTPS version. Unsupported browsers can’t load your site.
- Insecure - Visitors can access your site over both the standard connection (HTTP) and SSL secure connection (HTTPS). Sitemaps contain HTTP links and search engines index the HTTP version.
Choose a setting in the Security & SSL panel:
- From the Home Menu, click Settings.
- Under Website, click Security & SSL.
- Under Security Preference, choose a setting.
Note: If you're using a parking page, click Security & SSL in the main parking page menu, then choose a setting.
After enabling a security preference, your site can take up to 72 hours to process the update.
Some older browsers don’t support the high security standards required by our SSL certificates.
Unsupported browsers include:
- All versions of Internet Explorer on Windows XP
- Internet Explorer versions older than 7
- Firefox versions older than 2.0
- Safari versions older than 2.1
- Any Google Chrome version older than 6
Unsupported mobile browsers include:
- All versions of Safari running iOS older than 4.0
- Any Android browser running on a version older than 3.0 (Honeycomb)
- Any Windows Phone browser running on a version older than 7
Visitors loading your site on these browsers may have trouble loading the secure, HTTPS version of your site. In some cases, they might not be able to load it at all.
To avoid these issues, we recommend using a supported browser to visit or edit any Squarespace site.
Some pages on your site may have mixed content, meaning that the page loads over a secure HTTPS connection, but integrated content or third-party customizations load over an insecure HTTP connection. Mixed content on your website degrades HTTPS site security.
If you choose the Secure SSL setting for your site, your browser may display a warning when it loads mixed content. To avoid this, you can use the Insecure SSL setting, or experiment with other blocks that support your content securely.
SSL and Commerce
If you sell products with Squarespace Commerce, your checkout page is protected by SSL to keep your customers’ credit card data safe and secure. On checkout pages, we’re Level 1 PCI compliant and use 128 bit SSL encryption.
When a customer checks out on your store, they’ll see two signs that they're checking out securely:
- A lock icon in their browser
- A URL starting with https://secure.squarespace.com…
Here’s an example of a secure checkout page on Chrome:
Which setting should I use?
The best setting for your site depends on your site’s content and the type of visitors you anticipate. Most users will benefit from Secure, which provides a secure connection to all supported browsers.
Do I need a Squarespace Domain to use SSL?
No. SSL is available for any Squarespace Domains and third-party domains connected to your site. If you have a third-party domain, ensure that the domain is properly connected to your site by confirming your CNAME records and A records.
Can I use a custom certificate?
It isn’t currently possible to install a custom SSL certificate on a Squarespace site.
Will SSL work for subdomains?
Yes. Squarespace generates a certificate for each custom domain and subdomain connected to your website, whether it’s a Squarespace Domain or hosted by a third party.
If you have a third-party domain, ensure that it’s connected in your site’s Domains panel and not forwarded from another location.
Will SSL work on mobile browsers?
Yes. Your site is still protected by SSL as long as your visitors are using a supported browser.
Will SSL slow down my site?
You may notice a slight difference in site load time over HTTPS, as the secure connection takes time to authenticate the certificate and validate the site. In most cases, the difference is only a few seconds.
If you’re noticing a big difference in load time, use our troubleshooting steps to rule out other possible site issues, like content-heavy pages or custom code integrations.
I see a browser warning when I visit my domain.
If you've enabled the Secure setting in your Security & SSL panel, you may still see a privacy warning when you visit your domain. Depending on your browser, the message may be "Your connection is not private, "Your connection is not secure," or something similar. This happens when your browser detects insecure content on the page.
My Security & SSL panel shows a certificate status error. How do I fix this?
There are a couple error messages you might see in your Security & SSL panel.
If the message has a blue !, we're still processing the SSL certificate for your domain. You'll usually see this if you recently registered a Squarespace Domain, transferred a domain to Squarespace, or connected a domain. New domains may take up to 72 hours to fully connect to your site and generate a certificate.
If the error message has a red !, we couldn’t generate an SSL certificate for the listed domains. This usually happens when the domain isn’t properly pointing to your site.
- If you’re using a Squarespace Domain, ensure that your default records are intact.
- If you connected a third-party domain, double check your domain-mapping records to ensure your domain has the correct A records to work with Squarespace.
I’m using a third-party SSL provider for my site. Should I disable it?
If you’re using an external provider for SSL, like CloudFlare, you can disable this and use Squarespace’s automatic SSL protection for custom domains. However, note that Squarespace can’t generate a certificate for your domain until you point your domain to our servers. Your site’s existing HTTPS traffic will be unavailable while your DNS changes propagate and Squarespace generates the certificate. During this time, you may see a certificate error in your Security & SSL panel.
Will my custom domain appear during Commerce checkout?
No, but checkout is still secure and over HTTPS. When your customers check out on your site, they’ll see a URL starting with https://secure.squarespace.com.
Can I enable SSL on my Squarespace 5 site?
No. Squarespace only enables SSL for custom domains on Squarespace 7 sites.
Can I disable SSL?
It’s not possible to remove SSL certificates for your custom domains, as this keeps your site secure and ensures the best experience for your visitors. However, you can choose the Insecure option for your site, which still allows traffic over the standard HTTP connection.
