Best CIAM Software (2026): Top 8 Compared

Descope is a CIAM platform built around Flows, a drag-and-drop workflow editor for sign-up, login, MFA, SSO and step-up authentication. A flow controls both the user-facing screens, with granular styling controls, and the backend logic behind them. Descope states that teams can change authentication journeys without touching their codebase, and it also offers SDKs and APIs for teams that prefer code.

The platform splits its use cases into B2C and B2B. For consumer apps, Descope lists passwordless authentication, A/B testing of journeys and anonymous user tracking, with 1 million anonymous users included on Growth. For B2B apps, it lists self-service SSO and SCIM setup, zero-downtime SSO migration, multi-tenancy, delegated administration and fine-grained authorization. The Free plan already includes role-based access control, MFA and step-up authentication, secure session management and self-service admin widgets.

Security features include adaptive MFA that is enforced only on risky logins, using native and third-party risk signals, and bot protection on Growth. Identity orchestration connects user journeys to more than 50 third-party tools for provisioning and data syncs. Growth adds multi-region data residency, a HIPAA BAA and a FedRAMP High add-on.

Descope also prices AI agent use cases. It meters monthly active consents for MCP authentication and monthly active tokens for outbound app connections. In October 2026 its site banner announced Agentic Identity Hub 3.0, described as governance and control for AI agents.

Auth0 is the customer identity platform of Okta, Inc., which holds the copyright on its site. It positions customer identity around three goals: converting more sign-ups with passwordless authentication, social login, embedded login and progressive profiling; protecting accounts with adaptive MFA, risk-based authentication and attack protection; and keeping identity, consent and preferences connected across a brand's digital experiences.

The pricing page splits plans into B2C and B2B views. Free covers up to 25,000 monthly active users with passwordless login, unlimited social connections, basic attack protection, five Organizations and one enterprise connection, with self-service SSO and SCIM. Essentials adds Pro MFA, role-based access control per Organization, streaming of audit logs to Datadog, Splunk, AWS and Azure, and separate production and development environments. Professional adds logins against an existing user database, Enterprise MFA, custom token exchange and enhanced attack protection.

Enterprise adds custom user and SSO tiers, a 99.99% SLA and enterprise rate limits. Auth0 sells several add-ons: Fine-Grained Authorization, Attack Protection with breached password detection and bot protection, Adaptive MFA, machine-to-machine tokens, Private Cloud deployment, Highly Regulated Identity, and AI identity products for connecting AI agents to apps, APIs and MCP servers with human confirmation of critical agent actions.

Developer resources include quickstarts for more than 30 languages and frameworks, Actions and Forms for extensibility, and tools such as a JWT decoder and a passkeys playground.

Microsoft Entra External ID is Microsoft's CIAM product and, according to Microsoft's documentation, represents the convergence of business-to-consumer features into the Microsoft Entra platform. Microsoft states that Azure AD B2C has not been available for purchase by new customers since 1 May 2025, and it describes External ID as its next-generation CIAM solution.

Setup starts with a dedicated external tenant, separate from the employee tenant but following the same Entra tenant model. The external tenant holds a directory of customer credentials and profiles, application registrations using OpenID Connect or SAML, user flows for self-service sign-up, sign-in and password reset, and encryption keys. Custom authentication extensions add user attributes and data from external systems. Sign-in methods include username and password, one-time passcode, and Google, Facebook, Apple, Microsoft Entra ID and custom OIDC federation.

Microsoft's product page lists conditional access policies and multifactor authentication for external users, customisable branding and components, and lifecycle governance for business collaborators. Integrations cover Microsoft 365 collaboration across Teams, SharePoint and OneDrive, Visual Studio Code and Azure App Services.

Pricing runs through Azure. Microsoft's pricing page says the Basic tier is free for the first 50,000 monthly active users and that premium features are add-ons without a free tier. Microsoft Entra ID Governance for External Identities applies only to business guest scenarios.

Ping Identity sells customer identity as PingOne for Customers, alongside separate workforce identity packages. Its pricing page lists three customer packages: Essential, Plus and Passwordless.

Essential is built on a no-code identity orchestration engine with a drag-and-drop interface for building, testing and optimising identity experiences. It includes single sign-on across a company's digital properties, centralised authentication policies, customisable registration and sign-on screens, a unified customer profile accessible through REST and SCIM APIs, and self-service preference management. Ping states that all customer data is encrypted in every state. Inbound SCIM provisioning and an on-premises gateway for existing LDAP directories support organisations with older identity stores.

Plus adds adaptive multi-factor authentication that prompts only when context calls for it, with SMS, email, biometrics with mobile push, authenticator apps and FIDO2 security keys. A mobile SDK embeds MFA into customer apps and can make it invisible on trusted devices, and customers manage their own trusted devices through a self-service portal. Plus also includes transaction approvals for high-risk actions and API access management.

The Passwordless package combines SSO, user management, MFA and risk management with a getting-started wizard and pre-built flow templates, including migration of password users to passwordless. Ping also sells PingOne Verify for identity verification during registration and PingOne Protect for real-time risk scoring.

Stytch is an API-first authentication platform offering pre-built frontend components, headless SDKs and backend APIs, so teams can hand off as much or as little of the login experience as they choose. Its pricing page separates B2B SaaS and consumer use cases but states that features are not gated by plan.

The B2B product uses a multi-tenant, organization-first data model. Each organization can have its own primary and secondary authentication policies, multiple SSO identity providers over SAML and OIDC, SCIM provisioning and deprovisioning with automatic role management, and just-in-time provisioning by email domain or SSO connection. An embeddable admin portal lets a company's customers configure their own SSO, SCIM and user settings. Features are exposed through fine-grained APIs, so a single PUT request can change an organization's allowed authentication methods.

Fraud and risk prevention is a distinct part of the platform. Stytch lists bot detection, invisible CAPTCHA, device fingerprinting, customisable authorization verdicts and intelligent rate limiting, aimed at account takeover, credential stuffing and AI-driven attacks.

Stytch also markets a platform for AI agent authentication, authorization and consent management, with tooling for MCP authentication and detection of malicious or misbehaving agents. AI agents count toward the same 10,000 free monthly allowance as users.

FusionAuth describes itself as a CIAM platform built to deploy anywhere. Its homepage lists self-hosted, dedicated, on-premises, hybrid and air-gapped deployments, and every identity capability is available through an API. The Community edition is free and unlimited for self-hosting, while FusionAuth Cloud offers hosted plans.

Core features in every edition include unlimited users, groups and tenants, custom user and registration fields, JWTs and refresh tokens, lambdas, and full API access. Supported standards are OAuth 2.0, OpenID Connect and SAML v2. Authentication covers login, registration, single sign-on, passwordless magic links, passkeys and WebAuthn, social login, federated login, account locking and brute-force detection.

Paid plans add premium features: breached password detection, gaming identity providers, SAMLv2 IdP-initiated login, LDAP and legacy database integration, the client credentials grant, a self-service account portal, application themes, custom scopes, SCIM, threat detection and FIPS compliance. A HIPAA BAA is available. Advanced MFA methods include email, SMS and voice, and intelligent MFA policies include an impossible-travel signal.

Support scales by plan. Starter relies on community forums and GitHub. Essentials adds email tickets and engineering assistance, and Enterprise adds 24/7 phone support, a dedicated Slack channel with contract, solution architect guidance and a 99.99% SLA option. FusionAuth lists industry pages for healthcare, gaming, entertainment, fintech and retail.

Frontegg describes itself as a low-code CIAM platform and positions it mainly for B2B SaaS. The company states that multi-tenancy was part of the design from the start, so organisational structures, configurations, policies and branding can be managed per customer account.

Authentication features include a customisable login box and login builder, password, passwordless, social and enterprise SSO login, passkeys, MFA, session management, user impersonation and bot detection. For B2B use, Frontegg adds user invitations and groups, MFA and session policies per tenant, custom login boxes per tenant, and tenant-level IP and domain restrictions. A self-service admin portal can be embedded in the customer's app, so its customers manage their own users, roles, permissions and SSO setup.

Entitlements go beyond role-based access. Frontegg lists custom roles, permissions, ReBAC, feature flags, subscription management and ABAC, so access can follow a customer's plan or a feature flag. Hierarchies support nested tenant structures with granular access per level. Multi-app features cover several products under one identity layer, with external user pools and a federation broker.

Identity protection includes brute-force protection, new-device and suspicious-IP detection, impossible-travel detection, stale-user detection, step-up authentication and consent management. Frontegg also runs Agen.co, which governs AI agent access to enterprise context.

Clerk is a user management platform for developers, sold as APIs and prebuilt UI components for sign-up, sign-in and user profiles. Clerk manages the full session lifecycle, including active device monitoring and session revocation.

Authentication options include more than 20 social sign-on providers, email and SMS one-time passcodes with brute-force prevention, magic links and passwords with breach detection. Clerk states that built-in machine learning reduces fraudulent sign-ups through bot detection. Pro adds MFA, removal of Clerk branding, custom session lifetimes and satellite domains. Clerk also issues API keys and M2M tokens for users and machines, and the Clerk CLI lets AI coding agents set up Clerk from a terminal.

For B2B SaaS, Organizations provide multi-tenancy with custom roles and permissions, auto-join by email domain, invitations and organization UI components. Organization membership is capped at 20 members on Hobby and unlimited on paid plans. Clerk Billing adds subscription plans to B2C or B2B apps through React components, so access can be gated by plan without separate payment code.

Clerk's billing unit differs from most vendors. It counts monthly retained users, meaning users who return 24 or more hours after signing up, rather than every user who signs in. Startup discounts are offered through partners including Stripe Atlas, Y Combinator and South Park Commons, for companies up to one year after launch and $5 million in venture funding.
