Identity as a Service (IDaaS), also known as [identity and access management (IAM)](https://www.miniorange.com/iam/) as a service, is a cloud-based authentication solution managed by third-party providers. IDaaS firms offer cloud-based authentication or identity management services to enterprises on a subscription basis.

The concept of 'Anything-as-a-Service' (XaaS) in IT refers to delivering functionalities, such as identity management, through third-party providers via the cloud rather than deploying them on-site. For instance, Identity-as-a-Service (IDaaS) manages authentication and access control remotely, much like how Gmail provides email services over the cloud.

The primary objective of an identity service is to authenticate users—confirming they are who they claim to be—and to appropriately regulate their access to software applications, files, and other resources. Managing these services on-site can be difficult, particularly as new challenges arise, such as adapting identity provisioning systems to accommodate employees using a variety of devices under Bring Your Own Device (BYOD) policies. Conversely, IDaaS offers a streamlined, centralized cloud-based system developed by identity management experts. These specialists have extensive experience resolving common and complex identity issues across numerous organizations, making IDaaS a robust and efficient identity-as-a-service solution for modern enterprises seeking reliable access management without the complexity of in-house systems.


## Key Features of IDaaS {#Key Features of IDaaS}

Identity as a Service (IDaaS) provides a robust framework for managing identities and access in the digital age. Here are some key features that make IDaaS an important solution for modern enterprises:

- **Single Sign-On (SSO)**: [SSO](https://www.miniorange.com/products/single-sign-on-sso) simplifies the user experience by allowing individuals to access multiple applications and services with a single set of credentials. By minimizing the number of times users need to log in, the [SSO solution](https://www.miniorange.com/iam/solutions/sso-solution) enhances productivity and reduces the chances of password fatigue.
- **Multi-Factor Authentication (MFA)**: [MFA](https://www.miniorange.com/products/multi-factor-authentication-mfa) adds an extra layer of security by requiring users to provide two or more verification factors to gain access to resources, making unauthorized access significantly harder. With over [15+ MFA methods](https://www.miniorange.com/products/multi-factor-authentication-mfa-methods) available, organizations can tailor authentication processes to suit diverse user needs and scenarios, ensuring robust protection for sensitive data in various environments, particularly those involving Identity as a Service (IDaaS) providers.
