What is Identity as a Service (IDaaS) primarily used for?

Identity as a Service (IDaaS) is a cloud-based approach to identity and access management that provides organizations with solutions for managing digital identities. It enables the secure authentication and authorization of users across various cloud applications and services. IDaaS solutions typically include features such as single sign-on, multi-factor authentication, and user provisioning, making it easier for organizations to manage user access and ensure compliance with security policies.

The focus of IDaaS is on streamlining identity management processes through cloud services, which allows organizations to reduce the overhead associated with maintaining on-premises identity systems. This service is especially beneficial for businesses that rely heavily on cloud applications, as it provides a scalable and flexible way to manage user identities securely.

The other options focus on areas that do not pertain to the primary function of IDaaS. Physical security systems are concerned with physical access control rather than digital identity management. Developing mobile applications involves software development practices that are separate from identity management solutions. Encrypting sensitive information is related to data security rather than the management of user identities and access rights. Thus, the emphasis on managing identities through cloud services accurately captures the core purpose of IDaaS.
