AuthenticationAuthentication Verifying the identity of a user, process, or device, often as a prerequisite to allowing access to a system’s resources. is the act of determining that a person is who they claim to be.
When an end user logs in successfully (for example, using a username and password), the authentication system (the identity providerIdP An Identity Provider (IdP) is a software tool or service that offers user authentication as a service. The Identity Provider (IdP) manages the user's primary authentication credentials and issues assertions derived from those credentials. At UT Austin, the primary IdP used to authenticate the UT EID and EID Password is Enterprise Authentication, which is managed by the IAM Team.) will then certify to a consuming service (the service provider) that the end user is who they claim to be.
Not to be confused with authorizationAuthorization Access privileges granted to a user, program, or process or the act of granting those privileges., authentication only determines the identity of an end user. Authentication makes no decisions whether an end user should have access to a resource. The identity provider may, however, provide the service provider with information which allows the service provider to make an authorization decision.
The University’s authentication solutions can be found under Authentication in the service catalog.
Enterprise Authentication
The IAM Team offers the Enterprise Authentication service for campus-wide, web-based single sign-on. Enterprise Authentication is powered by a Security Assertion Markup LanguageSAML Security Assertion Markup Language (SAML) is a standard, XML-based language for exchanging authentication and authorization data between identity providers and service providers. This standard is currently used by Enterprise Authentication (as well as hundreds of service providers that integrate with our identity provider).

Multi-Factor AuthenticationMFA Authentication makes use of one or more factors of authentication: something you know (e.g., a password), something you have (e.g., your smartphone), or something you are (e.g., a fingerprint). Multi-Factor Authentication (MFA) makes use of two or more factors when authenticating you.
