Final Answer:
Certainly! The open standard for authorization used in websites and applications within Identity and Access Management is OAuth (Open Authorization).
Step-by-step explanation:
OAuth is an open standard protocol that allows secure authorization between different platforms, enabling users to grant access to their resources without sharing their credentials. It works by providing tokens to access specific resources on behalf of a user without exposing their password. The protocol operates through a series of steps: firstly, the client requests access from the resource owner; secondly, the resource owner authorizes the access request; and finally, the client is issued an access token by the authorization server, allowing access to the protected resources. This process ensures a secure and controlled access mechanism without compromising user credentials.
OAuth's significance lies in its ability to facilitate delegated access, enabling third-party applications to access resources on behalf of the resource owner with limited permissions, enhancing security and user control. It has become a widely adopted standard in the realm of identity and access management due to its versatility, security features, and ease of implementation. With OAuth, users can grant selective access to their data without sharing their credentials, maintaining a higher level of security and control over their information across various platforms and applications.
