Claims-based authentication is a type of authentication that uses a set of claims, or attributes, to establish the identity of a user. Claims are pieces of information about the user, such as their username, email address, role, or group membership.
In claims-based authentication, when a user attempts to access a resource, the resource owner requires the user to provide a set of claims that are associated with their identity. The resource owner then validates the claims to verify the user’s identity and determine whether they have the necessary permissions to access the resource.
Claims-based authentication can provide several benefits over traditional authentication methods. For example, it can simplify the process of managing user identities and access control by delegating the responsibility to identity providers, such as Azure Active Directory. Claims-based authentication can also support multi-factor authentication and can be used across different applications and systems, making it easier to integrate different systems and share resources securely.
