At-a-glance comparison
Microsoft Entra ID
Microsoft Entra ID (Azure AD) is identity and access management for organizations built on Microsoft 365/Azure. It’s the default workforce identity layer when conditional access and Microsoft ecosystem integration are priorities.
- ✓ Tight integration with Microsoft 365, Azure, and Windows management
- ✓ Conditional access and policy controls fit enterprise security teams
- ✓ Works well for workforce identity at scale with directory integration
OneLogin
OneLogin is workforce IAM for SSO and MFA across SaaS apps, often evaluated as an alternative to Okta or Entra in mixed enterprise environments. It’s a fit when governance and centralized workforce access are the goal.
- ✓ Workforce SSO across common SaaS apps with directory integrations
- ✓ MFA options suitable for standard enterprise security baselines
- ✓ Admin-centric workflows designed for IT/security ownership
What breaks first (decision checks)
These checks reflect the common constraints that decide between Microsoft Entra ID and OneLogin in this category.
If you only read one section, read this — these are the checks that force redesigns or budget surprises.
- Real trade-off: Entra is Microsoft-first workforce identity; OneLogin is a vendor-alternative workforce IdP for mixed environments.
- Workforce IAM vs Customer IAM (CIAM): Are you authenticating employees to many SaaS apps, or customers to your product?
- Build primitives vs buy a platform: How much engineering time can you spend on auth UX and edge cases?
Implementation gotchas
These are the practical downsides teams tend to discover during setup, rollout, or scaling.
Where Microsoft Entra ID surprises teams
- Microsoft-centric: non-Microsoft stacks can feel second-class
- Complexity increases across tenants, subscriptions, and governance needs
- Some advanced identity governance features require upgrades
Where OneLogin surprises teams
- Not designed for product-embedded customer CIAM use cases
- Governance maturity varies by org needs (access reviews/lifecycle depth)
- Integration depth depends on your SaaS estate and attribute mapping needs
Where each product pulls ahead
These are the distinctive advantages that matter most in this comparison.
Microsoft Entra ID advantages
- ✓ Strongest fit for Microsoft-first orgs (M365/Azure alignment)
- ✓ Conditional access integrates with Microsoft tenant and device controls
- ✓ Lower adoption friction where Microsoft identity is already default
OneLogin advantages
- ✓ Vendor-alternative workforce IdP option in mixed environments
- ✓ Workforce SSO/MFA focus for baseline identity consolidation

Pros and cons
Microsoft Entra ID
Pros
- + You are standardized on Microsoft 365/Azure and want lowest rollout friction
- + Conditional access needs to align with Microsoft device/tenant controls
- + You want identity to be part of the Microsoft security stack
- + You want fewer vendors and simpler procurement for workforce IAM
- + Your org has strong Microsoft admin expertise already
Cons
- − Microsoft-centric: non-Microsoft stacks can feel second-class
- − Complexity increases across tenants, subscriptions, and governance needs
- − Some advanced identity governance features require upgrades
- − Developer-first CIAM flows may be heavier than Auth0/Clerk/Firebase
- − Feature sprawl can make “what plan includes what” hard to manage
- − Cross-tenant and hybrid directory scenarios add operational work
- − Customization of login UX may be less flexible than CIAM-first tools
OneLogin
Pros
- + You have a mixed SaaS environment and want a non-Microsoft IdP option
- + Your needs are workforce SSO/MFA first, governance evaluated second
- + You want to compare vendor-alternative IAM workflows against Entra
- + You can clearly own app onboarding, attribute mapping, and policy rollout
- + You want flexibility in identity vendor selection over ecosystem coupling
Cons
- − Not designed for product-embedded customer CIAM use cases
- − Governance maturity varies by org needs (access reviews/lifecycle depth)
- − Integration depth depends on your SaaS estate and attribute mapping needs
- − Policy complexity can become operational debt without ownership
- − Switching costs increase once many apps depend on the IdP
- − Advanced enterprise requirements may push evaluation toward Okta/Entra
- − Migration/cutover still requires careful planning to avoid SSO outages
