Nobody wants to juggle a dozen passwords anymore. Not your IT team. Not your users. Definitely not your CISO.
We’ve talked to a lot of teams recently who are asking the same thing: “What’s the best SSO solution for us?” And it’s a fair question, because in 2025, there are more options than ever, but only a few that actually deliver on security, usability, and long-term value.
This list isn’t just another roundup of big names. We’re highlighting the tools that stand out either because they’re innovating fast, making SSO solutions easier to adopt, or just building smarter access control.
Here’s what’s working right now, and what to consider before you pick your next identity solution.
1. AuthX
We’ve seen a surge in healthcare, education, and manufacturing organizations adopting AuthX—and it’s not just because of its passwordless single sign on solution (though that’s a big part of it).
AuthX takes a practical approach to identity and access management. You can integrate Badge readers, Biometrics, AuthX Authenticator and risk-based policied, all without ripping and replacing your existing systems. It plays nicely with VDI environments, supports SAML and OIDC out of the box, and nails Zero Trust fundamentals without overcomplicating your stack.
Why do we like it:
- Seamless Single Sign-On One secure login for all your apps—cloud, on-prem, and virtual. AuthX makes SSO truly universal.
- Passwordless Authentication Reduces friction and increases security with Passkeys, Biometrics, Badge Tap, and Push-based logins—no passwords, just easy access.
- Ideal for Hybrid Workforces Designed for teams that move between devices, networks, and locations—without compromising security.
- Fast Deployment with Strong Compliance Roll out quickly while meeting HIPAA, CJIS, and other industry standards right out of the box.
- Contextual MFA + SSO Smart MFA that adapts based on user risk, location, and device—layered right into the SSO experience.
- Seamless Integration with Leading Platforms With a single secure login, AuthX automatically initiates virtual desktop sessions across major platforms like Citrix, IGEL, VMware, and ChromeOS.
- Directory + App Integrations
Works with Azure AD, Okta, Google Workspace, and more. Easy SSO across apps using SAML, OIDC, or APIs.
Best for: Healthcare, Education, Manufacturing, Retail, Law Enforcement, Finance, etc. and teams ready to ditch the password chaos.
2. Auth0
Auth0 (now part of Okta) continues to be a favorite for teams that want deep customization. If you’ve got devs in-house and need to support complex user flows, Auth0’s flexible SDKs and rule-based logic are a dream.
It also supports a wide range of login options—social, enterprise SSO solutions, passwordless—and gives you the tools to build login experiences that feel native to your product.
Why do we like it:
- API-first design
- Customizable login flows
- Great docs and community
- Strong security and compliance
Best for: Tech-forward companies that want full control.
3. Microsoft Entra ID (formerly Azure AD)
If you’re already deep in the Microsoft ecosystem, Entra ID is a no-brainer. It ties into Microsoft 365, Teams, SharePoint, and Azure services with ease.
We’ve seen organizations lean on its Conditional Access features to manage risk and identity-based policies across devices.
The catch? It can get complex if you’re not already a Microsoft shop. But if you are—this is your lane.
Why do we like it:
- Deep Office 365 integration
- Conditional Access + Identity Protection
- Hybrid AD support
Best for: Enterprises running on Microsoft stacks.
4. Okta
Still one of the most recognizable single sign on providers, Okta has matured into a reliable, scalable SSO solution. With over 7,000 pre-built integrations, it supports pretty much every SaaS SSO solution out there.
What stands out in 2025? Okta’s Lifecycle Management and advanced policy controls are robust. But fair warning—pricing and complexity scale quickly.
Why do we like it:
- Giant integration catalog
- Lifecycle automation
- Enterprise-grade policies
Best for: Mid-to-large orgs with complex access needs.
5. OneLogin
OneLogin positions itself as a simpler, more intuitive SSO provider. And for teams that want strong security without endless config screens, it delivers.
Its SmartFactor Authentication uses AI to decide when a login is risky. And its cloud SSO solution makes it easy to manage users across different platforms.
Why do we like it:
- Clean admin UX
- AI-powered MFA
- Fast onboarding
Best for: Teams that want an SSO platform that’s powerful and approachable.
6. Ping Identity
Ping Identity offers serious security horsepower. You’ll get everything from federated web SSO solutions to fine-grained access control, and their cloud-native SSO solution now plays much nicer with modern stacks than it used to.
It’s a solid choice for enterprise SSO solutions in high-stakes environments—think finance, healthcare, or government.
Why do we like it:
- Real-time identity intelligence
- Strong B2B/B2C capabilities
- Great for hybrid IT environments
Best for: Enterprises with security-first cultures.
7. JumpCloud
JumpCloud is an underrated gem, especially for small to mid-size businesses. It’s like a modern directory and SSO solution in one—and includes MDM (mobile device management) for free.
We’ve heard great feedback from IT teams that want fewer tools and more value packed into a single platform.
Why do we like it:
- SSO + MDM + Directory = Less tool sprawl
- Cross-platform support
- Budget-friendly
Best for: SMBs and lean IT teams.
8. Keycloak
Keycloak is the go-to choice for dev teams who want a fully open source SSO solution. It’s free, powerful, and supports SAML, OIDC, and social logins.
The tradeoff? You’ll need strong internal expertise to maintain and scale it.
Why do we like it:
- Fully open source
- Identity brokering and federation
- Dev-friendly architecture
Best for: DevOps-savvy teams that want full control.
9. Infisign
Infisign is quickly becoming a favorite among startups and SMBs looking for clean, affordable single sign on solutions. Their pitch is simple: passwordless SSO with AI-powered access decisions, built for speed.
It’s refreshing to see a newer vendor actually listening to IT admins and keeping things simple and secure.
Why do we like it:
- Clean UI
- Passwordless-first
- Affordable pricing
Best for: Startups and growing companies.
10. Gluu
Gluu is another open source SSO solution that has built a loyal following among security-conscious enterprises. It supports everything from FIDO2 to SAML and even strong authentication policies for healthcare and finance.
Expect a steeper learning curve—but if you’ve got the team, Gluu gives you a ton of freedom.
Why do we like it:
- Open source + customizable
- Built-in support for modern protocols
- Good enterprise tooling
Best for: Security-focused orgs with in-house IAM pros.
Here’s How to Choose
SSO isn’t just about fewer passwords. It’s about smarter access, faster workflows, and a more secure perimeter.
Want something plug-and-play? Some free SSO solutions or web SSO solutions can get you started fast but may lack enterprise features.
Need deeper control? On-premises SSO solutions and single sign on providers like Gluu or Keycloak give you more flexibility—if you’ve got the team.
Here’s our cheat sheet:
| Need | Best Pick |
|---|---|
| Passwordless + Compliance | AuthX |
| Dev Customization | Auth0/AuthX |
| Deep Microsoft Integration | Entra ID |
| Massive App Ecosystem | Okta |
| Fast Deployment | OneLogin/ AuthX |
| High-Security Use Cases | Ping Identity/ AuthX |
| Budget-Conscious | AuthX/ JumpCloud / Infisign |
| Full Control | Keycloak / Gluu |
Our Recommendation
Don’t start with features. Start with your identity gaps.
Are you trying to eliminate passwords? Secure your VDI setup? Modernize a clunky IAM process? Once you’ve got your biggest pain point in focus, the right SSO solution becomes a lot easier to spot.
If you’re in healthcare, education, or manufacturing—and especially if you’re dealing with shared workstations, remote access, or badge-based logins—we’d recommend starting with AuthX. It’s practical, powerful, and doesn’t overpromise.
And if you’re not ready for a full rip-and-replace? Good. The best SSO platforms in 2025
