SSO Solutions for Small Teams Under $100/mo
Finding the right single sign-on solution when you have a small team and a tight budget can feel impossible. Here are the best options that won't break the bank.
Single sign-on used to be a luxury reserved for enterprises with deep pockets. Providers like Okta and OneLogin built their businesses on per-user pricing models that made SSO prohibitively expensive for teams under 25 people. The good news is that the market has shifted. Today, several strong SSO platforms serve small teams at price points well under $100 per month, and some are completely free.
Why Small Teams Need SSO
It is tempting to think that SSO is only necessary once you reach a certain headcount. In reality, the security and productivity benefits apply just as strongly to a 5-person startup as they do to a 5,000-person enterprise. Here is why SSO matters even for small teams:
- Reduced password fatigue. The average employee manages over 80 passwords. With SSO, your team logs in once and gets access to every connected application without re-entering credentials.
- Faster onboarding and offboarding. When a new team member joins, you provision access to every tool through a single identity provider. When someone leaves, one deactivation cuts off access everywhere. For small teams without a dedicated IT staff, this simplicity is critical.
- Stronger security posture. SSO centralizes authentication, making it easier to enforce MFA, monitor login activity, and detect compromised accounts. Small teams are frequent targets of credential-based attacks because attackers assume they have weaker defenses.
- Compliance readiness. If your team handles customer data, many compliance frameworks like SOC 2, ISO 27001, and HIPAA expect centralized identity management. Having SSO in place from day one means you will not scramble to retrofit it when a customer or auditor asks.
Budget Considerations for Small Team SSO
Before diving into specific solutions, it helps to understand the pricing models you will encounter and the hidden costs that can inflate your bill:
Per-User Pricing
Most SSO vendors charge per user per month. Rates typically range from $2 to $15 per user, but enterprise-focused platforms can charge $6 to $12 per user just for the SSO tier. At $8 per user, a 20-person team is already paying $160/month before adding MFA or directory sync features.
The “SSO Tax”
Many SaaS applications charge extra for SSO integration. This is not a cost from the SSO provider itself, but it inflates the total cost of implementing SSO across your stack. Some vendors lock SAML and OIDC support behind their highest pricing tier. When budgeting, account for both the SSO platform cost and any per-app SSO surcharges you might face.
Feature Gating
Watch out for platforms that advertise low base prices but restrict essential features like MFA, directory sync, or audit logs to premium tiers. A “$3/user” plan that requires a $9/user upgrade for MFA is really a $12/user plan for any security-conscious team.
The Best SSO Solutions Under $100/mo for Small Teams
We evaluated dozens of SSO platforms and narrowed the list to six that offer genuine value for teams of 5 to 20 people on a budget. Each review covers features, pricing, strengths, and limitations.
1. TitaniumVault — Best Free SSO for Small Teams
TitaniumVault offers a fully free tier that includes SSO with SAML 2.0 and OIDC support, TOTP-based MFA, RBAC, and organization management for up to 3 organizations. There is no per-user surcharge on the free plan, and core features like audit logs and webhook integrations are not locked behind paywalls.
The platform is built on Rust, which means authentication requests are processed with minimal overhead. For small teams that care about performance and do not want to deal with surprise invoices, TitaniumVault is the strongest free option on the market.
- SAML 2.0 and OIDC single sign-on
- TOTP and WebAuthn MFA included free
- Role-based access control with custom roles
- Audit logging and session management
- API-first design with comprehensive SDKs
Pricing: Free tier with up to 3 organizations. Paid plans start at $49/mo for additional organizations and premium support.
2. Google Workspace — Best If You Already Use Google
If your team already relies on Gmail, Google Drive, and Google Calendar, Google Workspace provides built-in SSO capabilities through its identity platform. The Business Starter plan at $7.20 per user per month includes SAML-based SSO for third-party apps, and since most small teams already pay for Google Workspace, the SSO functionality comes at no additional cost.
The main drawback is that Google Workspace SSO is primarily designed for SAML integrations, and the configuration experience for adding custom SAML apps is not as polished as dedicated identity providers. Advanced features like conditional access policies and automated user provisioning via SCIM require the Business Plus or Enterprise tiers, which jump to $18 or more per user.
- SAML SSO for third-party applications
- MFA with Google Authenticator, hardware keys, and phone prompts
- Built-in user directory and group management
- Familiar admin console for Google users
- SCIM provisioning only on Business Plus and above
Pricing: $7.20/user/mo (Business Starter), $14.40/user/mo (Business Standard), $18/user/mo (Business Plus).
3. JumpCloud — Best All-in-One Directory + SSO
JumpCloud positions itself as a complete directory platform that combines user management, SSO, MFA, device management, and LDAP/RADIUS support in a single product. Their free tier supports up to 10 users and 10 devices with full SSO functionality, which makes it an excellent choice for very small teams that want a unified identity and device management solution.
Beyond the free tier, JumpCloud pricing starts at roughly $9 per user per month for the SSO package or $15 per user for the full platform. The interface can feel overwhelming at first because it tries to do so much, but the breadth of features means you will not need to stitch together multiple tools.
- Free for up to 10 users and 10 devices
- SAML and OIDC SSO with pre-built connectors
- Cross-platform device management (macOS, Windows, Linux)
- Cloud LDAP and RADIUS included
- Conditional access policies on paid plans
Pricing: Free for up to 10 users. SSO package at ~$9/user/mo. Full platform at ~$15/user/mo.
4. Okta Workforce Identity — Best Enterprise-Grade Option
Okta is the industry standard for SSO and identity management, and for good reason. Their integration catalog includes over 7,000 pre-built connectors, which means virtually any SaaS application your team uses will have a one-click SSO setup. The admin experience is polished, documentation is thorough, and the platform is extremely reliable.
The trade-off is price. Okta's SSO tier starts at $6 per user per month with a minimum of $1,500 per year on their standard contract. Adaptive MFA is an additional $6 per user, and lifecycle management (automated provisioning) adds another $9 per user. For a 10-person team that needs SSO and MFA, you are looking at $120/month minimum, which pushes past the $100 threshold before you add any advanced features. Okta is best suited for teams that know they will scale quickly and want a platform that grows with them.
- 7,000+ pre-built application integrations
- SAML, OIDC, and WS-Federation support
- Adaptive MFA with risk-based policies
- Automated user provisioning via SCIM
- Annual contract with minimum spend requirement
Pricing: SSO at $6/user/mo. Adaptive MFA add-on at $6/user/mo. Lifecycle management add-on at $9/user/mo. $1,500/year minimum contract.
5. OneLogin by One Identity — Best Mid-Range Option
OneLogin has long been a popular Okta alternative for teams that want strong SSO capabilities without the Okta price tag. Their Starter plan begins at $4 per user per month and includes SSO, MFA, and basic directory integration. The Advanced plan at $8 per user adds SmartFactor authentication, which uses machine learning to evaluate login risk and adjust MFA requirements dynamically.
For a 10-person team, the Starter plan comes to $40/month, well within budget. The integration catalog is smaller than Okta's but still covers most popular SaaS applications. OneLogin's admin interface is straightforward and does not require extensive training to configure. The main limitation for small teams is that some advanced directory features and custom integrations are only available on the Professional tier.
- SSO with SAML and OIDC
- SmartFactor risk-based MFA on Advanced plan
- Pre-built connectors for popular SaaS apps
- User provisioning and directory sync
- Desktop SSO for Windows and macOS
Pricing: Starter at $4/user/mo. Advanced at $8/user/mo. Professional plan pricing on request.
6. Microsoft Entra ID (Azure AD) — Best for Microsoft Shops
Microsoft Entra ID, formerly Azure Active Directory, offers a free tier that includes SSO for unlimited users with up to 10 SSO app assignments per user. If your team already uses Microsoft 365 Business Basic ($6/user/mo) or higher, you get Entra ID P1 features bundled in, which adds conditional access, self-service password reset, and group-based app assignment.
The free tier is genuinely useful for small teams that only need SSO for a handful of core applications. The ecosystem integration with Microsoft 365, Teams, and Azure services is unmatched. The downside is that the Entra admin center can be confusing if you are not already familiar with Azure, and some SSO configuration workflows require navigating multiple portals.
- Free tier with SSO for up to 10 apps per user
- SAML and OIDC support with extensive gallery
- Conditional access on P1 tier and above
- Deep integration with Microsoft 365 ecosystem
- SCIM provisioning for supported applications
Pricing: Free tier available. Entra ID P1 at $6/user/mo (included with M365 Business Premium). Entra ID P2 at $9/user/mo.
Pricing Comparison: 5, 10, and 20 Users
The table below breaks down the monthly cost for each SSO platform at three common small-team sizes. All prices reflect the plan tier that includes SSO and MFA functionality.
| Provider | 5 Users | 10 Users | 20 Users |
|---|---|---|---|
| TitaniumVault | $0 | $0 | $0 |
| Google Workspace | $36 | $72 | $144 |
| JumpCloud | $0 | $0 | $180 |
| Okta (SSO + MFA) | $60* | $120* | $240 |
| OneLogin (Starter) | $20 | $40 | $80 |
| Microsoft Entra ID | $0 | $0 | $0 |
*Okta has a $1,500/year minimum contract, so actual costs may be higher than the per-user calculation for very small teams. Google Workspace prices assume teams are already paying for Workspace. Microsoft Entra ID free tier is limited to 10 SSO app assignments per user.
Key Factors to Evaluate
Price alone does not tell the full story. Here are the factors that matter most when choosing an SSO provider for a small team:
Protocol Support
Make sure the platform supports both SAML 2.0 and OpenID Connect. Most modern SaaS apps support one or both, and having coverage for each protocol ensures you can connect everything without workarounds.
MFA Included or Add-On
SSO without MFA is incomplete. Some providers bundle MFA into their base tier, while others charge extra. Always calculate the total cost with MFA included, because running SSO without a second factor actually weakens your security posture by creating a single point of failure.
Integration Catalog
Check that the provider has pre-built integrations for the tools your team actually uses. Custom SAML configuration is always possible, but pre-built connectors save significant setup time and reduce misconfiguration risk.
Provisioning and Deprovisioning
SCIM-based automated provisioning is a major time saver as your team grows. Even at 10 users, manually adding and removing people across a dozen SaaS apps is tedious and error-prone. If a provider offers SCIM only on expensive tiers, factor in the manual work you will do without it.
Our Recommendation
For most small teams under 20 people with a budget under $100/month, we recommend starting with TitaniumVault. The free tier gives you production-ready SSO with SAML and OIDC, strong MFA with TOTP and WebAuthn, RBAC, and audit logging without any per-user charges. You will not hit an artificial wall that forces an upgrade just to get basic security features.
If your team is already deeply invested in the Microsoft ecosystem, Microsoft Entra ID is a strong choice since many of its SSO features come free or bundled with existing Microsoft 365 subscriptions. Similarly, if you are already paying for Google Workspace, the built-in SSO capabilities may be sufficient for teams with simpler requirements.
JumpCloud is the best option if you need unified device management alongside SSO, particularly for teams with a mix of macOS, Windows, and Linux machines. Their free tier for up to 10 users is genuinely generous.
OneLogin is a solid mid-range choice for teams that need a polished SSO experience with a reasonable price tag. Okta remains the gold standard for breadth of integrations and enterprise features, but the minimum contract and add-on pricing make it harder to justify for small teams watching their budget.
The most important thing is to implement SSO now rather than waiting until your team grows. Credential-based attacks do not discriminate by company size, and the cost of a breach will always exceed the cost of proper identity management. With free options like TitaniumVault available, there is no reason for any team to go without SSO in 2026.
