What does SSO (Single Sign-On) mean and How It Works in Enterprise Environments

Every day, employees face dozens of login screens. Each one demands a password, and each one slows them down. Single sign-on, or SSO, changes that. It lets users log in once and move freely across multiple applications. We are often asked, “What is single sign-on?” And this is important to understand, because understanding how SSO works means recognizing a shift – from scattered credentials to unified access. In enterprise environments, this simple idea transforms security and productivity alike.

Tired of multiple logins? Akku’s SSO/IDP offers one-click access to all your apps – secure, efficient, and enterprise-ready.

Single Sign-on (SSO) Meaning: One Login, Multiple Benefits

Let’s begin with the meaning of SSO. The full form of SSO is Single Sign-On. At face value, it’s a convenience tool. Log in once and you’re in to everything. But its essence is deeper. SSO is not just about reducing logins. It’s about streamlining identity, about turning chaos into clarity.

So, what is SSO? What is single sign-on? It’s the idea that authentication should be unified. You prove your identity once, securely, and gain access to multiple systems. Think of it as a backstage pass. Instead of knocking at every door, you’re granted a badge. That badge, cryptographically signed and verified, opens every room you’re authorized to enter.

How Does SSO Work? – A Unified Login Solution Explained

The Core Components Behind SSO

To understand how SSO works, imagine an office building. You enter through the main door and show your ID at reception. After that, you walk freely between departments. That’s the idea behind SSO integration.

Step-by-Step SSO Authentication Flow

Here is a step-by-step overview of the SSO authentication process:

  • The user requests access to a protected application.
  • The application redirects the user to an identity provider.
  • The identity provider checks for an active authentication session.
  • If none exists, the user is prompted to enter credentials.
  • After verification, the identity provider issues a secure token.
  • The token returns to the application, which validates it and grants access.

This process happens almost instantly. Technologies like SAML, OAuth, and OpenID Connect make sure identity information moves safely and reliably. These protocols build the trust that modern systems depend on.

If you’re considering how to approach SSO implementation, the answer lies in building trust between systems, leveraging token-based communication, and ensuring encrypted interactions between identity and service providers.

Common SSO Protocols

The widely adopted protocols supporting SSO include

  • SAML (Security Assertion Markup Language): Common in enterprise environments.
  • OAuth: Designed for authorizing third-party access without sharing passwords.
  • OpenID Connect: Built on OAuth for richer identity information and enhanced user experience.

Why Do Enterprises Need SSO Today?

Increased Productivity Through Reduced Login Fatigue

Imagine an employee who needs to check Salesforce, Zoom, Jira, and Notion – all before their first coffee. Without SSO, that’s four logins. With it, just one. That’s time saved. Focus preserved. And that mental energy is redirected toward work that matters.

Improved Security (No Password Reuse, Better Authentication)

Having many passwords often leads to poor security. Users tend to reuse passwords, write them down, or choose weak ones. With SSO, there is only one password to protect. And it’s easier to remember one strong password than multiple weak ones.

Better It Efficiency (Centralized Control And Fewer Reset Requests)

Ask any IT admin what the most common ticket is. Password resets. SSO drastically reduces these. With SSO integration, access becomes a switchboard. IT can turn permissions on or off, audit usage, and streamline offboarding – all from a central dashboard.

Support For Hybrid/Remote Workforces

Whether an employee logs in from the office, their home, or a café, SSO applications deliver a consistent experience. That’s the power of centralized identity. Location no longer dictates access. Trust does.

Single Sign-On (SSO) Applications & Examples

Consider this single sign-on example: a new hire joins your company. On day one, they sign in with their corporate credentials. Instantly, they’re in Gmail, Slack, Trello, and the company wiki. They don’t need to ping IT. They don’t need setup guides. They just start.

That’s the magic of SSO. It’s invisible when it works. And indispensable once adopted. Here are some more examples…

Finance: One Login, Instant Access

A junior analyst walks into the office on day one. She logs in with Akku SSO. Instantly, she’s inside the trading platform, the reporting dashboard, and the compliance portal. No waiting. No IT calls. In a business where milliseconds cost millions, this isn’t convenience – it’s strategy.

Healthcare: Saving Time to Save Lives

A doctor moves between patients, tablets in hand. With a single sign-on, she pulls up scans, lab results, and schedules without breaking stride. Akku SSO makes it seamless. The fewer seconds spent logging in, the more time she has to do what matters – care for people.

IT: Build and Deploy Faster

An engineer flips between Jira, GitHub, and AWS. With Akku SSO, it’s one login for everything. No sticky notes, no reset links. Workflows. Security holds. Akku doesn’t just streamline – it gives IT what it always wanted: control without compromise.

What are some alternatives to Okta?

In this new world of remote working and cloud enterprises, Identity and Access Management (IAM) has been thrust to the fore. It’s almost as if the economy now relies on agile and automated IAM systems to enable rapid and seamless digital transformation.

Okta is the leading player in the area of IAM, and has made major strides forward in the field by harnessing artificial intelligence, and thus going beyond merely using the password and other multi-factor authentication options.

Okta has several advantages such as its security, scalability, and simplicity. But cost-wise, Okta works better for larger enterprises and can prove to be quite expensive for smaller organizations.

Though Okta is a popular choice, that doesn’t mean it is your only option. There are several other options out there for enterprises looking to go the IAM way, each with its own advantages. 

Some of these alternatives include Active Directory Federation Services (ADFS), OneLogin, and Akku for instance and we’re going to give you the lowdown on each of them.

1. Active Directory Federation Services (ADFS)

Developed by Microsoft, ADFS is a Single Sign-On (SSO) solution and is a component of Windows Server operating systems.

ADFS is preferred by many enterprises as it is perceived to be more stringent on privacy issues when compared to other tech majors; and more convenient as most enterprises use Windows Active Directory (AD) for user management already, meaning there is no environment change if you are adding on ADFS.

But like with Okta, initial costs are high, and there are hidden infrastructure and maintenance costs as well. For instance, commissioning ADFS requires a Windows Server license, which comes at a cost. 

Also, ADFS tends to be complex and needs substantial technical know-how to use properly. Commissioning, configuring, and maintaining an ADFS solution is time-consuming and customer support too, though free, is not very user-friendly. 

2. OneLogin

OneLogin, another market leader, brings to the table secure, one-click access, through all device types. Advantages are that OneLogin comes pre-integrated with over 4000 apps, offers multiple language options, and integrates with popular directories such as Active Directory (AD) and G Suite, thereby offering flexibility for growing businesses. 

But like with Okta and ADFS, here too, pricing can be steep for smaller enterprises. It is also complex to use and though it integrates with AD, it offers limited analytics on the admin console, user support time is not ideal, and adding new apps can be tricky.

3. Akku

Akku (yes, that’s us) is an emerging player in the Asia Pacific region. While it comes with all IAM features, it has been developed specifically keeping the needs of small and medium sized businesses in mind. It is therefore ideal for teams of 10-300 people and companies looking for high ROI and responsive support. 

So, if you are a smaller enterprise, a fast-growing start-up, or a business in any industry where value for money is an important consideration, Akku presents a sensible option. Another advantage here would be that it provides enterprises with complete control over data access and privacy on the cloud while staying compliant with statutory standards.

Akku isn’t a one size fits all option and because of the bespoke nature of the solution, it takes more time than Okta to purchase and set up. But once you are all set up, it is simple to use, and offers all the IAM functionalities you will need at a fraction of the cost of the other options listed here.

So, there are options out there for IAM beyond Okta. And while a strong IAM strategy is integral to productivity and security, you’ve got to choose one that fits your requirements and your budget. If you are a small or medium-sized business looking for an IAM solution, with an eye on customization, contact Akku today.
