SAML (Security Assertion Markup Language) employs transient identifiers to enhance user privacy and prevent user identification during Single Sign-On (SSO) operations. Transient identifiers are temporary and unique for each user session, which means they do not retain information about the user once the session ends.

This mechanism ensures that even if the identifier is intercepted, it cannot be reused for tracking the user across sessions or different applications. By using transient identifiers, SAML minimizes the risk of user identification and enhances overall security during SSO, supporting the principle of minimal data exposure.

In contrast, persistent identifiers remain the same across sessions and can be used to track user activity over time, which does not align with the privacy goals SAML aims to achieve. Direct user tokens and static session keys do not provide the same level of anonymity and can expose user identity or session data, undermining the mechanism's intent to protect user identity during authentication processes.
