In this day and age, it is more important than ever to implement SSO authentication. Through a unified authentication and authorization protocol known as single sign-on (SSO), users are granted access to several enterprise applications with just a single username and password. With federated single sign-on (SSO), a user can log in to multiple domains’ worth of applications or websites with just one set of credentials. <\/p>\n\n\n\n

What is SSO?<\/span><\/h2>\n\n\n\n

Users can log in to numerous websites and applications using a single set of credentials thanks to a technique called single sign-on, or SSO. SSO simplifies the user authentication process. Logging into one app automatically logs the user into all other apps in the user’s ecosystem that share the same domain, platform, or technology. This simplifies the process of remembering and reusing login credentials for a wide range of online resources.<\/p>\n\n\n\n

By signing in once with Google, for instance, a user’s credentials are verified across all of Google’s affiliated services, including Gmail<\/a> and YouTube<\/a>, eliminating the need for the user to log in again and again. As long as there is a shared identity provider (IdP) that authenticates users and issues tokens or certificates granting access to the connected services, SSO can also function across domains or organizations.<\/p>\n\n\n\n

Single sign-on (SSO) is an integral part of many IAM and access control systems. Understanding who needs what access requires verifying users’ identities. Service and identity providers exchange and validate login credentials for SSO to function. Generally speaking, a service provider (SP) is a vendor that offers goods and services to individuals and groups, like websites or applications. An identity provider (IdP) is a system that establishes, controls, and upholds user identities in addition to offering services for user authentication. Through the reduction of password fatigue, these reputable providers enhance the user experience by enabling users to use SSO to access websites and apps. <\/p>\n\n\n\n

How does Single Sign-On (SSO) Work?<\/span><\/h2>\n\n\n\n

SSO is an identity federation tool that is also a part of federated identity management (FIM). Identity and access management (IAM) is a framework that helps businesses securely authenticate new users and devices when they connect to a network. One of the main functions of IAM is identity verification. Assigning user access permissions and making sure users only have the minimal amount of access necessary to perform their jobs well depends on this. <\/p>\n\n\n\n

The SSO service generates an authentication token to keep track of the user’s verification status each time they sign in. This digital information is kept on the user’s browser or the servers of the SSO service, and it works much like a temporary ID card for the user. Every app that the user opens will request the SSO service. When the user logs in, the SSO service sends the app its authentication token. In contrast, should the user not have already logged in, they will be directed to do so via the SSO service. <\/p>\n\n\n\n

Because it does not store user identities, an SSO service may not always be able to recall a user’s identity. Rather, they function by comparing a user’s login details with those already on file in an identity management service or database. <\/p>\n\n\n\n

View SSO as a mediator that can verify if a user’s login credentials correspond to their identity within the database, all without the need for database management.<\/p>\n\n\n\n

Benefits of Single Sign-On (SSO)<\/span><\/h2>\n\n\n\n

#1. Increased Productivity<\/span><\/h3>\n\n\n\n

SSO makes sure that users can access numerous apps or services with just one password. By doing this, you can prevent password fatigue, which is the inability of individuals to recall unique passwords for various accounts, which can result in the reuse of login credentials across various services. This poses a serious security risk since hackers can access other accounts by using passwords that are frequently used. <\/p>\n\n\n\n

Users save time by only having to sign in once to access applications. This enhances productivity levels by reducing the likelihood that they will use weak passwords or forget their login information.<\/p>\n\n\n\n

#2. Fewer Help Desk Tickets<\/span><\/h3>\n\n\n\n

Since users only need to remember a single login to access all of their accounts, the IT support team sees a decrease in requests for password resets. IT staff will have less of a need to respond to requests to reset passwords via the help desk. Instead, they have more time to dedicate to projects that matter to the company.<\/p>\n\n\n\n

#3. Stronger Security<\/span><\/h3>\n\n\n\n

SSO prompts users to use a stronger password. This aids them in not using the same password for different accounts. It is simpler for users to recall their passwords when they only need to use one login for multiple services. Since websites no longer need to store user credentials, this lowers the risk of cyberattacks against organizations.<\/p>\n\n\n\n

However, two-factor authentication (2FA), which adds additional assurance that the user is who they claim to be, should at the very least support passwords. <\/p>\n\n\n\n

#4. Less Shadow IT Risks<\/span><\/h3>\n\n\n\n

When people utilize software, hardware, services, or apps that are not authorized for official use, they are engaging in shadow IT\u2014a practice that involves circumventing security policies within their organization. By keeping an eye on which apps staff members are using, SSO helps businesses prevent this. It also enforces compliance policies and lowers the risk of data loss and identity theft. <\/p>\n\n\n\n

What is the SSO Federation?<\/span><\/h2>\n\n\n\n

SSO is a function of FIM that allows users to log into a wide variety of services with just one set of credentials. The benefit of using a single sign-on (SSO) service is that once a user logs in, they will have access to all of the associated applications and websites. SSO is a part of FIM’s process of granting users safe access to their accounts.<\/p>\n\n\n\n

The resources that users can access are what make FIM and SSO different. For example, SSO lets users access different systems and apps that are connected to the same organization, while FIM lets users access resources from different organizations.<\/p>\n\n\n\n

Users can safely access numerous online applications with a single set of login credentials thanks to a system called single sign-on, or SSO. For example, it’s what lets you browse your Gmail account in one tab and use YouTube in another tab when you sign in to your Google account. To facilitate the exchange of identities and the authentication of users across domains, a trusted relationship must be established between autonomous organizations and third parties, such as partners or application vendors, through federated identity management, also known as federated single sign-on (SSO). Through federation, users only need to log in once to a single domain to gain access to all of the services and resources available across both domains. Single Sign-On (SSO) is a subset of FIM. <\/p>\n\n\n\n

You can use the terms SSO and FIM interchangeably, but they have important distinctions. Signing in once grants you entry to all of the services and content you need within the same domain. Federated identity management facilitates single sign-on to applications from different domains or organizations. <\/p>\n\n\n\n

How does it Work? <\/span><\/h2>\n\n\n\n

Federated identity management is an extension of single sign-on that enables us to gain access to multiple providers’ services with just one set of login credentials. Similar to Single Sign-On (SSO), Federated Single Sign-On (SSO) is compatible with a wide variety of authentication protocols. Using metadata and certificate configurations, trust is built between the identity provider\u2014a system that keeps track of and authenticates user identity\u2014and the service provider\u2014the system the user wishes to use. After establishing a trustworthy connection, users can log in to service providers using their identity providers’ credentials. <\/p>\n\n\n\n

Range of Access and Scalability<\/span><\/h3>\n\n\n\n

The access that each mechanism allows is the main difference between them. While both methods grant users access to a wide variety of resources after a single login, SSO restricts that access to just one or a small group of affiliated businesses. Identity federation, on the other hand, allows users to access resources from multiple domains within the federated network.<\/p>\n\n\n\n

Complexity and Cost<\/span><\/h3>\n\n\n\n

FIM solutions are typically more complex and expensive to run because of the much greater access they provide. They call for more careful management of resources and may necessitate specialized knowledge for setup and upkeep. For FIM to work, it is also necessary for different identity providers to develop trustworthy connections with one another.<\/p>\n\n\n\n

Ultimately, FIM or SSO costs depend on your company’s size, the number of apps you want to integrate, and your security and compliance laws. With the help of federated single sign-on (SSO), users with accounts on Cloud Identity Service can easily access services offered by one or more partner companies without having to log in separately at each partner’s website.<\/p>\n\n\n\n

With this setup, employees who require access to multiple services at once (Zoom<\/a>, Office 365, Google Workspaces, HR Portal, etc.) only need to remember and use one set of login credentials to access them all.<\/p>\n\n\n\n
