• Need self-hosted/open-source: Keycloak
• Consumer/mobile app: Firebase Authentication

If you want, I can also give you a top 5 ranked by price, ease of use, or best for B2B vs B2C.

If you’re a startup, the best identity provider depends on your stack and customer type. My short list:

• Best overall for product-led startups: Clerk — very generous free tier, polished prebuilt UX, and clear scaling pricing. It currently offers 50,000 monthly retained users free and B2B org features in all plans. (clerk.com)
• Best for B2B SaaS / enterprise-readiness: WorkOS — strong for organization modeling, SSO, SCIM, and “future-proof” enterprise auth. (workos.com)
• Best if you want a classic enterprise CIAM platform: Auth0 — mature, broad feature set, and a startup program that includes 100K monthly external active users free for a year. (auth0.com)
• Best for fast, low-friction auth with good startup pricing: Stytch — its self-serve pricing was updated to 10,000 B2C MAUs / 10,000 B2B MAUs free and a lower paid platform fee. (changelog.stytch.com)
• Best budget / simplest if you’re already on Google Cloud: Firebase Auth — good if you already use Firebase/Google Cloud, with auth included in Firebase pricing and pay-as-you-go pieces for some features. (firebase.google.com)
• Best if you’re AWS-native: Amazon Cognito — integrates tightly with AWS, and AWS documents Cognito pricing directly. (aws.amazon.com)
• Best no/low-code alternative: Descope — startup-friendly, with a Free Forever tier and a startup program offering Pro free for a year. (descope.com)

My practical recommendation

• B2C app: Clerk or Stytch.

If you want, I can give you a ranked top 3 for your exact startup (B2B vs B2C, budget, tech stack, and whether you need SSO/SCIM).

For remote teams, the best identity provider (IdP) platforms are usually:

Best overall

• Okta Workforce Identity — very strong for SSO, MFA, lifecycle management, and lots of app integrations. Great for mid-size to large remote companies.
• Microsoft Entra ID (Azure AD) — best if you already use Microsoft 365, Teams, or Windows-heavy endpoints. Strong conditional access and device management.
• Google Cloud Identity — best for Google Workspace-first teams. Simple, affordable, and easy to roll out.

Best for fast-growing startups

• JumpCloud — good all-in-one directory + SSO + device management for remote-first teams.
• OneLogin — simpler and often more affordable than Okta, with solid SSO/MFA.

Best for enterprise or security-heavy teams

• Ping Identity — strong for complex enterprise environments and advanced access policies.
• Okta — still one of the strongest choices here, especially for broad SaaS app coverage.

Best for developer-heavy teams

• Auth0 — best if you need customer identity or custom authentication flows, not just employee access.
• WorkOS — great for adding SSO/SCIM for internal SaaS tools or custom apps.

What matters most for remote teams

Look for:

• SSO + MFA
• Conditional access
• SCIM provisioning/deprovisioning

• Good mobile support
• Strong app catalog
• Easy onboarding/offboarding

Quick picks

• Best overall: Okta
• Best for Microsoft shops: Microsoft Entra ID
• Best for Google shops: Google Cloud Identity
• Best startup-friendly option: JumpCloud

If you want, I can also rank them by price, ease of setup, or security features.

For most remote teams, these are the best fits:

• Microsoft Entra ID — best if you’re already on Microsoft 365/Windows, because it pairs SSO with Conditional Access and MFA for device/location-based policies. (learn.microsoft.com)
• Okta Workforce Identity — best all-around enterprise option for mixed app stacks; it’s strong on SSO, MFA, lifecycle management, and device trust. (okta.com)
• JumpCloud — best for smaller or lean IT teams that want identity plus device management in one place, with MFA and remote-device control. (jumpcloud.com)
• Cisco Duo — best if your main goal is simple, strong MFA-first access with SSO, phishing-resistant auth, and device checks. (duo.com)

Strong MFA + SSO + broad app integration.

If you want just one recommendation: Microsoft Entra ID for Microsoft-heavy orgs, otherwise Duo for easiest best-in-class MFA.

If you tell me your setup (small business, enterprise, cloud stack, budget), I can pick the best fit.

If you want one default pick, Microsoft Entra ID is the best all-around identity provider for MFA for most organizations—especially if you already use Microsoft 365/Azure. Microsoft supports passkeys (FIDO2), Windows Hello for Business, FIDO2 security keys, and says it recommends phishing-resistant methods as the most secure sign-in experience. (learn.microsoft.com)

Best by use case:

• Microsoft Entra ID — best overall, especially Microsoft-heavy shops. (learn.microsoft.com)

My short recommendation

• Best overall: Auth0
• Best enterprise: Okta or Microsoft Entra ID
• Best AWS-native: AWS Cognito
• Best self-hosted: Keycloak or FusionAuth

If you tell me your stack (AWS/GCP/Azure, B2B vs B2C, SaaS vs internal API), I can narrow it to the best 2–3 options.

For API authentication, the best identity providers are usually these:

• Auth0 — best all-around for developer-friendly API auth, especially if you need OAuth 2.0 / OIDC, JWT access tokens, and machine-to-machine (client credentials) flows. Auth0 explicitly supports M2M apps and API access tokens. (auth0.com)
• Okta — strong enterprise choice if you want a standards-based OAuth 2.0 authorization server with API Access Management and scoped access tokens. (developer.okta.com)
• Microsoft Entra ID — best if you’re already in the Microsoft ecosystem; it provides standards-compliant OAuth 2.0 / OIDC endpoints and supports calling web APIs, including on-behalf-of flows. (learn.microsoft.com)
• Amazon Cognito — best if your stack is on AWS; Cognito user pools act as an OIDC IdP and support authorization-code and client-credentials flows, plus JWT authorizers for APIs. (docs.aws.amazon.com)
• WorkOS — best for B2B SaaS if your main need is enterprise SSO across customer IdPs; it supports SAML/OIDC and is designed to abstract the authentication handshake. (workos.com)
• FusionAuth — solid self-hosted / flexible option if you want more control over auth infrastructure and standard OAuth-style flows. (fusionauth.io)

My short recommendation:
