TL;DR: Key Points
- SSO is only available for Squarespace Enterprise plans
- Use authentication apps like Okta, Google, or Microsoft Entra ID for setup
- Customise the SSO login page to match your brand
- Enable SSO for specific pages or your entire site
- Work with your IT team for proper setup and configuration
- Each authentication provider has specific requirements
What Is SSO?
Single Sign-On (SSO) is a security system that lets users log in once to access multiple applications or sites. On Squarespace, SSO means your team or clients can access protected pages without juggling multiple passwords.
Setting Up SSO for Your Squarespace Site
Choose Your Authentication Provider
First, pick and configure an authentication application. Your options include Okta, Microsoft Entra ID, ClassLink, or Google. Each provider needs specific details:
- Okta: You'll need the client ID and client secret
- Google: Requires the X.509 certificate
- Microsoft Entra ID: Setup uses your tenant ID
- ClassLink: Only works if you're already using it with your Squarespace account
Customise the SSO Login Page
Your login page should look like part of your brand. Here's how to customise it:
- Go to your site settings and open the Design panel
- Click "SSO Login Screen" to edit background images, fonts, and colours
- Use the Branding & Text panel to add your logo and adjust text styles
This keeps your brand consistent, even on login screens.
Setting Up Site-Level SSO
This protects your entire site:
- Go to Site Availability settings
- Choose "SSO protected" then "Select SSO" to pick your method
- Save changes to protect all pages
Setting Up Page-Level SSO
For protecting specific pages (useful when different people need access to different areas):
- In the Pages panel, hover over a page and click its settings
- Toggle "Require SSO to access page" and select your SSO method
- Save your settings
Testing tip: Always test your SSO setup in a private browser window. This simulates how real users will experience it and avoids any cached login states that might hide problems.
