What is SSO? A 2025 Guide to Single Sign-On for Businesses

Managing logins for multiple apps—email, CRMs, collaboration tools—can slow down employees and overwhelm IT teams. Single Sign-On (SSO) solves this by streamlining access while boosting security. In this guide, we’ll explain what SSO is, how it works, why it’s essential for businesses, and how 42Gears’ SureIdP with SureMDM delivers a powerful SSO solution for businesses, especially for mobile workforces.

What is Single Sign-On (SSO)?

Single Sign-On (SSO) allows users to log in once with a single set of credentials to access multiple applications. It’s like a master key: one login unlocks your email, project management tools, and cloud storage without needing separate passwords.For example, an employee logs in using an Identity Provider such as 42Gears’ SureIdP and instantly gets access to Google Workspace, Salesforce, and internal apps. This single sign-on solution saves time and reduces frustration, with studies showing employees can lose up to 20 hours annually on password-related issues.

How Does SSO Work?

SSO relies on an Identity Provider (IdP), like 42Gears’ SureIdP, to verify user identities. Here’s the SSO implementation process in simple terms:

1. User Logs In: The employee enters their credentials on the IdP’s login page.
2. Authentication: The IdP verifies the credentials, often using Multi-Factor Authentication (MFA) for added security.
3. Token Issued: The IdP sends a secure token to connected apps, confirming the user’s identity.
4. Seamless Access: The user accesses all apps without logging in again.

Why Businesses Need SSO

SSO boosts efficiency and security, and SureIdP with SureMDM makes it a top SSO solution for businesses. Here’s why it’s a must-have:

1. Skyrockets Productivity

Employees lose hours weekly on logins and password resets. SSO eliminates this, letting teams focus on work. For example, a retail chain using SureIdP with SureMDM cut login times by 25%, boosting in-store efficiency.

2. Strengthens Security

Fewer passwords reduce breach risks. SureIdP centralizes authentication, supporting MFA and real-time monitoring. If an employee leaves, disabling their SureIdP account revokes access instantly. SureMDM ensures secure device access, protecting mobile and desktop environments. Learn more about secure device management with SureMDM.

3. Simplifies IT Management

Managing accounts across apps is complex. SureIdP streamlines this through one platform, while SureMDM integrates SSO to manage app access on devices, saving time and reducing errors.

4. Delights Users

SureIdP eliminates password overload, meaning no more helpdesk calls or sticky notes. A smooth login experience boosts morale and app adoption, especially for remote teams.

SSO for Mobile Workforces: A Game-Changer

Remote and mobile workforces rely on apps accessed from various devices. SSO for mobile workforces ensures seamless, secure access to tools like CRMs or inventory systems, whether employees are in the field or at home. SureIdP with SureMDM excels here, enforcing SSO policies on mobile devices to prevent unauthorized access. For example, field technicians can log in once on their tablets and access all apps without repeated logins, saving time and reducing security risks.

SSO vs. Multi-Factor Authentication (MFA): What’s the Difference?

SSO and Multi-Factor Authentication (MFA) serve distinct roles:

• SSO simplifies access by reducing logins.
• MFA adds security with extra verification, like a phone code.

Together, they’re unbeatable. With SureIdP, employees can log in once with a password and MFA, then access all apps seamlessly.

Real-World SSO Success: A 42Gears Case Study

A mid-sized logistics company reported struggles with employees accessing apps on mobile devices, requiring password resets all the time, and even having weaker passwords causing security concerns. By implementing SureIdP with SureMDM, the company unified access to its communication, inventory, and CRM apps. The result? A 30% reduction in IT support tickets and faster onboarding for drivers and other warehouse workers, with SureMDM ensuring secure device management.This case highlights how SureIdP with SureMDM transforms workflows for mobile workforces.

What to Watch Out For

SSO is powerful, but consider these challenges:

1. Single Point of Failure: If the IdP fails, app access stops. SureIdP’s high uptime and backup authentication options mitigate this risk.
2. Legacy App Compatibility: Older systems may not support SSO. SureIdP offers tools to bridge gaps, and 42Gears’ support team can guide integration.

The long-term savings in IT support and security make SSO, powered by SureIdP, a smart investment.
