The standard recommended for ensuring identity portability in cloud setups is SAML (Security Assertion Markup Language). SAML is an open standard for exchanging authentication and authorization data between parties, particularly between an identity provider and a service provider.

SAML enables single sign-on (SSO) solutions, which means that once users authenticate through a single identity provider, they can access multiple services without needing to log in again. This feature is particularly valuable in cloud environments, where users often interact with various applications and services provided by different vendors.

One of the significant advantages of SAML is its capability to facilitate secure exchange of user identity information across different domains, making it easier for organizations to utilize multiple cloud services while maintaining consistent identity management practices. By providing a standardized way to declare user identities and permissions, SAML allows organizations to achieve greater interoperability and flexibility when integrating various cloud-based applications.

While OAuth, XML, and JWT are also related to identity and access management, they serve different roles. OAuth primarily focuses on delegated access (allowing third-party applications to access user data without sharing passwords), XML is a markup language used for data interchange, and JWT (JSON Web Token) is a compact method for representing claims to be transferred between two parties. Each of these has its
