Security Assertion Markup Language. Security Assertion Markup Language ( SAML, pronounced SAM-el, / ˈsæməl /) [1] is an open standard for exchanging authentication and authorization data between parties, in particular, between an identity provider and a service provider.
Single sign-on. Single sign-on ( SSO) is an authentication scheme that allows a user to log in with a single ID to any of several related, yet independent, software systems. True single sign-on allows the user to log in once and access services without re-entering authentication factors. It should not be confused with same-sign on (Directory ...
The Registration Data Access Protocol ( RDAP) is a computer network communications protocol standardized by a working group at the Internet Engineering Task Force in 2015, after experimental developments and thorough discussions. It is a successor to the WHOIS protocol, used to look up relevant registration data from such Internet resources as ...
Hardware authentication security keys. Multi-factor authentication ( MFA; two-factor authentication, or 2FA, along with similar terms) is an electronic authentication method in which a user is granted access to a website or application only after successfully presenting two or more pieces of evidence (or factors) to an authentication mechanism.
Federated identity. A federated identity in information technology is the means of linking a person's electronic identity and attributes, stored across multiple distinct identity management systems. [1] Federated identity is related to single sign-on (SSO), in which a user's single authentication ticket, or token, is trusted across multiple IT ...
Platform as a service (PaaS) or application platform as a service (aPaaS) or platform-based service is a category of cloud computing services that allows customers to provision, instantiate, run, and manage a modular bundle comprising a computing platform and one or more applications, without the complexity of building and maintaining the infrastructure typically associated with developing and ...
Mutual authentication or two-way authentication (not to be confused with two-factor authentication) refers to two parties authenticating each other at the same time in an authentication protocol. It is a default mode of authentication in some protocols ( IKE, SSH) and optional in others ( TLS ). Mutual authentication is a desired characteristic ...
The Central Authentication Service ( CAS) is a single sign-on protocol for the web. [1] Its purpose is to permit a user to access multiple applications while providing their credentials (such as user ID and password) only once. It also allows web applications to authenticate users without gaining access to a user's security credentials, such as ...
