SSO stops Shadow IT by letting IT teams check which apps employees use. This lowers the risk of identity theft¹.

What is Single Sign-On (SSO)?

Single Sign-On (SSO) lets users log into many applications with just one set of login details³. This means no more remembering different passwords for each service. It makes logging in easier³. Both big and small organizations, as well as individuals, use SSO to make accessing platforms simpler³.

Definition and Overview of SSO

SSO checks a user’s identity and lets them into many connected applications or systems³. When a user tries to get into a service, they’re redirected to an Identity Provider (IdP) for checking³. After verifying the user, the IdP gives an SSO token back to the user and the service provider checks this token to let the user in³.

How SSO Works: The Basic Workflow

The basic steps of SSO are as follows:³

User tries to get into a service.
The service asks the user to log in and sends them to the IdP.
The IdP asks for the user’s login info and checks it.
After checking, the IdP gives an SSO token to the user’s browser.
The browser sends the SSO token to the service.
The service checks the token with the IdP and lets the user in.

This makes it easy for users to get into many platforms without logging in each time³.

Some SSO services use Kerberos or SAML to make logging in and checking permissions easier³. Big tech companies like Google, LinkedIn, Apple, Twitter, and Facebook also offer SSO. This lets users log into websites and apps with their social media accounts³.

Overall, SSO makes it easy and safe for users to get into many applications and services. It also makes the login process more secure³⁴⁵.

The History and Evolution of SSO

The story of single sign-on (SSO) technology started with early identity management tools in the 1990s⁶. These tools helped connect computers, networks, and servers securely. Companies used systems like Microsoft’s Active Directory (AD) and Lightweight Directory Access Protocol (LDAP) to manage user identities.

Now, with the move to cloud services and new cybersecurity threats, old identity management tools are outdated. Cloud-based SSO solutions have become popular for their quick and secure access to applications⁶. These solutions offer many features, including managing user accounts and access, all in one package⁶.

Standards like SAML, SCIM, and JIT have helped SSO evolve, making it easier for different systems to work together⁶. But, IAM solutions have gotten more complex and expensive, making them hard for small businesses to afford⁶.

So, smaller companies are looking for simpler and cheaper identity management tools. YeshID is one option that offers clear pricing and smart defaults to help with digital identity management⁶.

“The shift to cloud-based services has necessitated the evolution of traditional identity management tools, leading to the rise of comprehensive SSO solutions that provide secure, convenient access to a wide range of applications.”

Protocols and Standards for SSO

The IAM world uses many industry-standard protocols and frameworks for secure, easy single sign-on (SSO). SAML, OAuth, and OpenID Connect (OIDC) are key in this area.

SAML (Security Assertion Markup Language)

SAML is an open standard that makes user info readable for machines. It helps apps check if a user is who they say they are⁷. SAML 2.0 is great for web apps, sending identity info through a browser.

OAuth and OpenID Connect (OIDC)

OAuth lets users share their data with apps without re-entering their info⁷. OIDC adds user checks on top of OAuth 2.0, making SSO possible across many apps.

⁷ OIDC uses JSON Web Tokens for info sharing between providers, making logging in easier⁷. SAML is an XML standard for SSO within companies and across domains.

⁷ OAuth 2.0 has many parts like the Resource Owner and Authorization Server⁷. It helps with social logins and accessing APIs, making things easier for users.

Protocol	Purpose	Use Cases	Technology	Tokens	Actors
OIDC	Authentication	Social login, Enterprise SSO	JSON Web Tokens	ID Token, Access Token	Identity Provider, Client, Resource Owner
SAML	Authentication, Authorization	Enterprise SSO, Federated SSO	XML	SAML Assertion	Identity Provider, Service Provider
OAuth 2.0	Authorization	Social login, API access	JSON	Access Token	Resource Owner, Client, Authorization Server, Resource Server

These protocols and standards help IAM solutions offer secure, easy SSO for users across different apps and services.

Benefits of Implementing single sign-on (SSO)

Single sign-on (SSO) makes identity and access management (IAM) better for organizations. It cuts down on the need for remembering many usernames and passwords. This makes the user experience and productivity better⁸.

With SSO, employees can easily access all their work tools with just one set of login details. This saves time and reduces frustration, making employees happier and more engaged⁸. It also cuts down help desk calls by 75%, making things more efficient and saving money on IT costs⁸.

Improved User Experience and Productivity

SSO makes logging in easier, letting users get to all their work apps and services with one set of login info. This saves time and cuts down on password-related stress, making employees more satisfied and engaged⁸. Plus, it reduces help desk calls by 75%, boosting productivity and cutting IT costs⁸.

Enhanced Security and Reduced Attack Surface

SSO is more secure than old password systems. It uses a single strong password, lowering the chance of password-related data breaches. These breaches make up 61% of all data breaches, says the Verizon Data Breach Investigations Report⁸.

SSO also cuts down on the risk of phishing and other security threats by reducing password fatigue and bad password habits⁸. It can automatically log users off and quickly take away access, meeting compliance needs and stopping unauthorized data access⁹.

This level of control and visibility makes IAM strategies stronger, creating a safer and more efficient IT setup.

In conclusion, a strong SSO system brings many benefits. It improves user experience, productivity, security, and meets regulatory needs. With the IAM market expected to nearly triple by 2028⁸, SSO is key to the digital growth of businesses today.

Types of SSO Implementations

Identity and access management (IAM) has seen a big change with single sign-on (SSO). It makes logging into many applications and websites easy and safe. There are three main ways to use SSO: Enterprise SSO, Web-Based SSO, and Federated SSO.

Enterprise SSO

Enterprise SSO helps big companies with lots of IT stuff. It uses one identity provider (IdP) to check who you are and let you into all the apps and websites you need¹⁰. Big names like Google, Microsoft, Amazon, and IBM use it. It lets their workers move easily between different tools and services.

Web-Based SSO

Web-Based SSO makes it easier to get into many websites. It uses one IdP to check who you are, so you don’t have to log in over and over¹⁰. For example, “Sign in with Google” lets users use their Google account to get into different websites and apps.

Federated SSO

Federated SSO is like SSO on steroids. It lets you log in with one IdP and get into apps and websites from different companies¹⁰. It’s great for companies working with partners or having lots of different apps and websites. It makes things more secure and easier to manage across different groups.

SSO Implementation	Characteristics	Adoption
Enterprise SSO	Single IdP for all applications within an organization	¹¹ 37% of SSO implementations are specifically for enterprise use
Web-Based SSO	Single IdP for accessing multiple websites	¹¹ 7% of SSO implementations are social-based
Federated SSO	Single IdP for accessing applications across organizational boundaries	¹¹ 4% of SSO implementations are used by academic institutions

Choosing the right SSO depends on what an organization needs. Things like IT setup, security, and working with others outside the company matter. Knowing about these options helps companies pick the best way to improve authentication, authorization, and access control in their identity and access management (IAM) plans.

On-Premises vs. Cloud-Based SSO Solutions

Organizations have two main choices for single sign-on (SSO): on-premises or cloud-based solutions. Each has its own benefits and things to consider. It’s important for organizations to think about their security, compliance, and how they work before choosing.

On-premises SSO means setting up and running hardware and software in your own place. It gives you full control over your SSO setup. This is good for companies with strict authentication and authorization rules or special access control needs. But, it can be expensive upfront and needs a lot of work to keep it running and growing.¹²

Cloud-based SSO is on someone else’s servers, making it flexible and cheaper. Cloud providers use SSO to give easy and safe access to cloud services.¹² By 2022, Gartner says 80% of access management will use IDaaS.¹³ This way, companies don’t need to worry about hardware or upkeep. They can rely on the cloud provider for security and following rules.

On-Premises SSO	Cloud-Based SSO
Complete control over the SSO environment Suitable for organizations with specific security and compliance requirements Higher upfront costs and significant resources for maintenance and scaling	Hosted on a provider’s infrastructure More flexible and cost-effective approach Reduced hardware and maintenance needs Leverages the cloud provider’s security and compliance measures

Traditional on-premises SSO is costly to run and maintain, needing a lot of time and resources just to work.¹³ Okta can cut the number of servers needed for traditional on-premises SSO by up to 90%.¹³

The choice between on-premises and cloud-based SSO depends on what an organization needs, its budget, and its IT setup. By looking at these things, organizations can pick an identity and access management strategy. This strategy should meet authentication, authorization, and access control needs while being cost-effective and good for users.

Challenges and Considerations for SSO Adoption

Single sign-on (SSO) brings many benefits, but its adoption has challenges. Security and privacy issues, along with the complexity of setting it up, are key factors to think about when using an SSO solution.

Security and Privacy Concerns

If an SSO system’s login details are hacked, it could let bad actors into many systems. 51% of users forget or reset their passwords weekly,¹⁴ and 57% reuse passwords on different sites,¹⁴ making them more vulnerable. To fix this, using SSO with Multifactor Authentication (MFA) is crucial to keep out unauthorized users.

Implementation Complexity

Setting up an SSO system is hard and takes a lot of time. Security teams must link their systems with Identity Providers (IdPs), set up trust, and make sure it works with various apps. Most SaaS startups aren’t ready for an enterprise’s SSO needs,¹⁵ and SSO setup for big companies can take weeks or months.¹⁵ To overcome this, having the right experts and a solid plan is key to avoid problems and keep the system safe.

SSO has big benefits, but it’s important to consider security, privacy, and setup complexity for a successful and safe use of this IAM solution.

Real-World Examples of SSO in Action

Many organizations and platforms now use single sign-on (SSO) for its ease and security¹⁶. By 2022, 87% of EMEA organizations had adopted SSO¹⁶. Big names like Google, Microsoft Azure AD, and Amazon Web Services (AWS) use it. So do popular social sites like Facebook Login and big business tools like Salesforce¹⁶.

These companies use protocols like SAML, OAuth, and OpenID Connect to make signing in easy across many apps and services¹⁶¹⁷. This has made things better for users, more secure, and easier to manage access¹⁶.

Google lets users get into Gmail, Google Drive, and Google Docs all with one set of login info¹⁷. Microsoft Azure AD gives a full IAM platform for SSO with Microsoft and other apps¹⁷. Amazon Web Services (AWS) also has SSO, letting users get into many AWS services with one set of login details¹⁷.

SSO has big benefits but also needs careful thought on security and privacy. It must also fit well with what’s already there¹⁶. Yet, real-world examples show how SSO makes things smoother, better for users, and more secure¹⁶.

Securing SSO: Best Practices and Risk Mitigation

Using a strong Single Sign-On (SSO) system is key for any company’s IAM. But, it also brings risks that need to be fixed. To lower these risks, adding SSO with MFA and strong IGAM practices is a must.

Integrating SSO with Multi-Factor Authentication (MFA)

Adding MFA to SSO makes it more secure. MFA asks for more proof of who you are, like a code or your face, besides your SSO login. This stops hackers even if they get your login details¹⁸.

Identity Governance and Access Management

Strong IGAM practices keep an eye on who can do what in a company. IGAM sets up access based on job, department, and level, making sure everything is clear. This way, access can be taken away fast if needed¹⁹.

By doing these things, companies can make their SSO safer and avoid big security problems. It’s also important to check security often, manage user accounts well, and follow privacy laws closely.

Best Practices for Securing SSO	Benefits
Integrate SSO with Multi-Factor Authentication (MFA)	Adds an extra layer of security to prevent unauthorized access
Implement Identity Governance and Access Management (IGAM)	Maintains control and visibility over user access rights and privileges
Regularly audit and monitor the SSO system	Ensures ongoing compliance and identifies potential security risks
Manage user lifecycle and session management	Reduces the attack surface and minimizes the risk of unauthorized access
Comply with data privacy regulations	Protects personally identifiable information (PII) and maintains trust

“Securing SSO is crucial, as a single point of failure can have widespread consequences. Integrating MFA and implementing robust IGAM practices are essential to mitigate the risks and ensure the overall security of the IAM infrastructure.”

By following these tips, companies can enjoy the benefits of SSO safely. They keep a tight grip on their IAM systems¹⁸¹⁹.

Conclusion

Single Sign-On (SSO) has changed how organizations handle identity and access management (IAM), authentication, and authorization. This tool makes it easier for users to get into systems, makes things more secure, and helps businesses work better²⁰.

SSO uses protocols like SAML, OAuth, and OIDC. This means users can log into many apps and services with just one set of login info, cutting down on password hassles²¹. More and more, SSO is key in both new and old apps, showing it’s a big chance for SSO companies²⁰.

SSO brings many upsides, like better user experience, more security, and easier management. But, it’s important for companies to think about security, privacy, and other issues to make SSO work well²¹. Adding SSO to a strong access management strategy can make things more secure, improve how users feel, make things run smoother, and cut IT costs on passwords²².
