The best SSO providers in 2025 are solving three core problems: fragmented access, rising credential-based attacks, and poor user experience across cloud and on-prem systems. They support standards like SAML, OIDC, and SCIM, offer robust MFA options, and provide centralized policy control across thousands of endpoints.
Whether you’re looking to modernize legacy infrastructure or standardize identity in a zero-trust model, these providers offer more than just convenience. They deliver operational efficiency and stronger security outcomes. This guide breaks down the 10 best sso solutions that are leading the market in 2025, with a focus on capability, reliability, and enterprise readiness.
But before we get to the list, let’s address a foundational question: What exactly is Single Sign-On?
What is a Single Sign-on (SSO)?
Single Sign-On (SSO) is an authentication method that lets users access multiple applications with one set of login credentials. It works by centralizing login through a trusted identity provider, which verifies the user and grants access across platforms. For users, it means fewer logins and less password fatigue. For IT and security teams, it means stronger control, simplified management, and reduced risk from weak or reused passwords. If your organization uses multiple applications, SSO is one of the fastest ways to improve both user experience and security posture.
In this blog, let’s look into some of the best SSO providers out there in 2025. We will also touch upon the importance of SSO-MDM integration.
10 Best SSO Solutions to Enhance Your Security
In a traditional authentication system, users are required to enter their credentials (a combination of username/user ID and password) for each separate application or system they want to access. With SSO, a user only needs to authenticate once with a central identity provider, and then they can access multiple systems or applications configured to trust the identity provider.
There are many SSO tools in the market. But, We have handpicked some of the top single sign-on solutions businesses must consider in 2025 to level up their security and access management game.

Each of these single sign-on solutions providers brings its unique strengths and features to the table. Businesses should evaluate their specific needs and consider scalability, integration capabilities, security requirements and user experience when choosing the most suitable single sign-on software.
Importance of Single Sign-On (SSO) & UEM Integration
The integration between SSO and MDM solutions is crucial for businesses for several reasons:
Enhanced Security
The integration of single sign-on and MDM allows for stronger security measures. MDM solutions enable businesses to enforce device-level security policies, such as data encryption, passcode requirements, and remote data wipe. These actions need to be performed with extreme caution.
When the MDM platform is integrated with a single sign-on solution, users can authenticate themselves using their preferred single sign-on before accessing the dashboard, ensuring that only authorized individuals can gain access. This reduces the risk of unauthorized access and inappropriate actions on the MDM platform.
Simplified User Experience
SSO and MDM integration creates a seamless and convenient user experience. IT teams managing devices using an MDM solution can log in to their corporate dashboard using their work email credentials once and gain automatic access to all authorized applications and resources via single sign-on solution. This eliminates the need for users to remember and repeatedly enter multiple usernames and passwords, streamlining the authentication process and improving productivity.
Centralized and Remote User Management
Integration between SSO and MDM provides centralized user management capabilities. User provisioning and deprovisioning can be automated, ensuring that access to the MDM platform is granted or revoked based on employee role and association with the company.
This simplifies the administration process, reduces manual efforts, and enhances security by promptly removing access for users who no longer work for the organization or are no longer required to access the MDM platform.
Cost and Time Savings
SSO-MDM integration reduces administrative overhead and saves time and costs associated with managing user accounts, passwords, and device configurations separately. Centralized user management, automated provisioning, and consistent security policies streamline processes and minimize the need for manual intervention.
How to Choose the Best SSO Provider: A Simple Guide
Choosing the best SSO provider is not just about tech specs. It is about making logins safer, smoother, and stress-free for everyone in your organization. Whether you are looking for the best single sign-on solution or comparing the top SSO providers, here is what really matters when picking the right one:
1. It Should Work Well With What You Already Have
The best SSO solutions don’t make you change everything. They work smoothly with your current tools, systems, and apps. They should support login standards like SAML, OIDC, or OAuth so your IT team can plug them right in.
Also, make sure the SSO tool doesn’t need special hardware or network changes. Ask questions like “Can it connect with what you already use like Active Directory or LDAP?” If yes, you are off to a good start. A good single sign-on solution should save time, not create more work.
2. Strong Security Comes First
The best SSO software should make your life easier without cutting corners on security. Look for providers that use strong encryption and support multi-factor authentication (MFA). This keeps accounts safe even if someone’s password is stolen.
And don’t forget about compliance. A top SSO provider should meet rules like:
- HIPAA for healthcare
- PCI DSS for companies handling credit cards
A good single sign-on software protects your users and your business.
3. It Should Make Life Easier for Users
The single sign-on provider should keep things simple. Logging in once should give users access to everything they need, there should not be any need for extra passwords or constant prompts.
It is even better if users can handle things on their own, like changing passwords or checking their login history without needing help from IT. A good SSO tool makes things easy so your team can get work done without distractions.
4. It Should Be Fast and Scalable
You don’t want logins to slow down your day, especially when everyone signs in at once. A good SSO provider should handle peak times without crashing or lagging.
Make sure the system can grow with your business too. Whether you add more apps, more users, or expand to new locations, the single sign-on solution should scale effortlessly.
5. Flexibility Matters
No two businesses are the same. That is why the best SSO tool should give you the flexibility to:
- Customize login rules
- Change the user interface
- Add new platforms or apps as you grow
The best SSO solution is one that fits into your current setup, keeps your logins secure, makes life easier for users, and grows with you. Keep these basics in mind while searching for a single sign-on provider because when SSO works well, it disappears into the background making your login experience seamless, secure, and stress-free.

SSO requires an identity provider (IdP), user directory, supported applications, authentication protocols like SAML or OpenID Connect, and security measures like MFA to manage and secure centralized authentication effectively.
4. What Problems Does SSO Solve?
SSO addresses password fatigue, reduces password-related support requests, simplifies onboarding/offboarding, improves productivity, and enhances security by centralizing user authentication and enforcing consistent policies across applications.
5. How Does SSO Contribute to Preventing Shadow IT?
SSO prevents Shadow IT by offering users secure, convenient access to approved applications. By simplifying access, it encourages employees to use authorized tools, ensuring IT oversight, security compliance, and streamlined resource management.
