SAML SSO
Also written: SAML, Single Sign-On
SAML SSO is a standard for secure single sign-on, letting users access multiple applications with one login.
SAML Single Sign-On (SSO) is a way for businesses to manage user access to different software applications. Instead of creating and remembering separate usernames and passwords for each tool, employees can use one set of credentials to log into everything.
Imagine you have a company account that gives you access to your email, your company's internal wiki, and a project management tool. With SAML SSO, you log in once to your company's main system, and that single login automatically grants you access to all those other applications without needing to log in again. This makes it easier and more secure for employees to work.
Security Assertion Markup Language (SAML) Single Sign-On (SSO) is an open standard protocol that enables identity providers (IdPs) to pass authentication and authorization data to service providers (SPs). It uses XML-based assertions to communicate user identity and access rights, allowing users to access multiple independent software systems with a single set of credentials. SAML SSO simplifies user management and enhances security by centralizing authentication and reducing the number of credentials users must manage.
As AI models become more integrated into enterprise workflows, secure access and user management are critical. SAML SSO allows organizations to manage access to these powerful AI tools through their existing identity systems, simplifying administration and enhancing security for sensitive data.

You can't directly try SAML SSO in 5 minutes as it requires setup by an IT administrator. However, if your workplace uses SAML SSO for tools like Google Workspace or Microsoft 365, you are already experiencing it. Log in to your work account once, and then try accessing another work application like your email or calendar without logging in again.

Questions people ask
- What is the main benefit of SAML SSO?
- The main benefit is improved user experience and security. Users only need to remember one password, and administrators can manage access centrally.
- Is SAML SSO the same as just logging in with Google or Facebook?
- It's similar in concept, but SAML SSO is typically used for enterprise applications and is managed by the company's IT department, whereas Google/Facebook logins are consumer-focused.
