B2B SaaS tool list
Best B2B SaaS Customer-Identity Tools in 2026
Written by the editorial team. Pricing information is taken from each vendor's own pricing page or quoted by sales; this guide does not publish prices we could not confirm at the vendor.
For most B2B SaaS teams that need to add enterprise single sign-on, directory sync and audit logs without rebuilding login from scratch, WorkOS is the most direct first candidate, because it is built around the enterprise features that B2B buyers ask for during procurement. Its pricing is on request, so the right first step is to request a quote based on your organization count and the connections you need, not on a per-seat guess.
Customer identity sits on two boundaries at once. It is a security boundary, because a mistake in login, recovery or tenant isolation exposes customer data. It is also a product experience, because a slow or confusing sign-in flow costs trials and renewals. The tools below cover both sides, but they differ widely in how much engineering they expect your team to own.
This guide covers identity and authentication tools only. It does not rank workflow automation or email platforms, and it does not treat any vendor as a security certification. Confirm every security claim against your own threat model and the controls you actually configure.
How this shortlist was built
The shortlist has twelve tools. Each one is listed because it addresses a recognizable B2B SaaS identity problem: authenticating end users, serving enterprise customers who require SSO, managing organizations and roles inside a multi-tenant product, or giving an engineering team control over the identity stack. The list is not a ranking by quality. A tool that suits a five-person product team can be the wrong choice for a company selling to regulated enterprises, and the reverse is also true.
Each vendor is described from its public product information. Where a vendor publishes a price, the price should be read from its pricing page on the day you evaluate it, because identity pricing commonly depends on monthly active users, organizations, enterprise connections, authentications and support tier. Where no price is published, we say so and do not estimate one.

Choosing by the problem you actually have
Most buying mistakes in customer identity come from choosing a tool for the feature list rather than for the first problem it has to solve. A B2B SaaS product usually hits one of four triggers. The first is the first enterprise prospect who asks for SSO through their identity provider. The second is a self-serve product that needs social login, passwordless sign-in and account recovery that does not generate support tickets. The third is a multi-tenant product where one customer must never see another customer’s data, which puts the weight on organization modeling and role design. The fourth is a compliance or procurement review that asks where identity data lives and who can administer it.
Name your trigger before you open a vendor page. If the trigger is enterprise SSO, the candidates are mainly WorkOS, Okta, Ping Identity and the enterprise capabilities of Auth0. If the trigger is a self-serve login rebuild, Clerk, Stytch, Descope and Auth0 are the usual starting points. If the trigger is control over hosting and data location, FusionAuth, Ory, Zitadel and Authgear deserve a longer look. If you already run on AWS, Amazon Cognito is worth a direct comparison because it sits inside the same account, billing and IAM model as the rest of your infrastructure.
Pricing: what to request before you compare numbers
None of the twelve vendors in this guide has a price that we can state here with confidence for your situation, so the table below lists the quantities you should put in a quote request. Identity vendors commonly price on a mix of users, organizations, connections, authentications and support level. A quote for a small product and a quote for an enterprise tenant base can differ in structure, not just in size, so ask every vendor to price the same scenario in writing.
| Team profile | What to put in the quote request | Price |
|---|---|---|
| Early B2B product, a few hundred accounts | Monthly active users, number of organizations, social login, one SSO connection for a pilot customer | Pricing on request |
| Growing mid-market product, several thousand end users | Monthly active users across organizations, SSO connections, SCIM directory sync, audit log retention, support tier | Pricing on request |
| Enterprise platform with complex tenancy | Tens of thousands of users, many enterprise connections, custom domains, data residency requirements, uptime commitments | Pricing on request |
Where a vendor publishes a self-serve price page, read it for the billing unit it uses. Where it does not, expect a sales conversation. Either way, do not compare a per-user figure from one vendor with a per-organization figure from another until both have been converted into the same scenario from the table above.
Tool-by-tool notes
WorkOS
WorkOS is the most common first answer for a B2B SaaS team whose sales cycle has started to hit SSO questions. Its public product information centers on SSO, directory sync and audit logs, which are the three things enterprise buyers usually request before signing. For a team that already has a working login system but cannot yet serve a large customer, that focus can shorten the path to the first enterprise deal.
Where it falls short is the part that stays with you. WorkOS can handle the connection to a customer’s identity provider, but your product still decides which roles map to which permissions, what happens when a user is removed from a directory, and how an admin recovers a locked-out organization. Plan that design before the first integration. Pricing is on request, so ask for a quote that includes the number of enterprise connections you expect in the first year.
Okta
Okta is a large identity platform that many enterprises already use for employee access. Its value for a SaaS company is most visible when your customers are also Okta customers and expect the same administrative model, lifecycle controls and multi-factor policies they run internally. It covers authentication, lifecycle management, MFA and access governance, which makes it a broad platform rather than a narrow login component.
The tradeoff is that workforce identity and customer identity are different problems. Staff accounts, contractor access and the accounts your own customers create in your product have different lifecycles and different risks. Before adopting Okta for customer-facing login, confirm which use cases it is being bought for and whether one design can serve both without making customer sign-up harder than it should be. Pricing is on request.
Auth0
Auth0 is aimed at product teams that want to embed authentication and authorization into their own application rather than sending users to a separate login experience. Its developer orientation makes it a practical choice for teams with strong engineering capacity who want to control the sign-in flow, the token model and the way users are linked across social and enterprise connections.
The planning burden is real. Tenant design, environment separation between development and production, and the way you model organizations all affect what you can change later. Pricing is on request, and it is worth asking how the price changes as your user base grows, because a plan that fits a pilot can look very different at full production volume.
Stytch
Stytch offers authentication, fraud and identity APIs aimed at product teams that want to assemble their own login experience. It suits a team that has a clear design for passwordless sign-in, step-up checks and fraud signals and needs an API layer to implement that design rather than a complete hosted login page.
Because the APIs give you flexibility, they also give you responsibility. Engineering ownership and a security review of the flows are required before launch, particularly around account recovery and session handling. Pricing is on request.
Descope
Descope targets teams that want to build identity flows with little code, combining visual flow building with API access for the parts that need custom logic. For a product team that changes its sign-up journey often, that split can keep product and engineering aligned without a release for every copy or step change.
Evaluate how the flows are versioned, tested and promoted between environments, and whether governance over who may change a production flow is clear. Those questions matter more as the number of teams touching identity grows. Pricing is on request.
Clerk
Clerk is built for web teams that want user management, organizations and ready-made interface components without building the account pages themselves. For a product that needs a working sign-in and organization switcher quickly, the component approach saves a large amount of front-end work.
The question to settle early is data-model fit. If your product needs an unusual relationship between users, accounts and billing entities, confirm that the organization model can express it before you build on top. Customization limits and how far you can change the default interface should be tested with your real design. Pricing is on request.
FusionAuth
FusionAuth is an option for teams that want authentication, authorization and user management with control over where the system runs. Self-hosting can matter for buyers who require data to stay in a specific environment, and the managed option can matter for teams that do not want to run identity infrastructure themselves.
Self-hosting moves operational work onto your team: patching, backups, scaling, and planned upgrades. Price the people time alongside any license cost. Pricing is on request, so ask for both the managed and self-managed scenarios if you are still undecided.
Ory
Ory provides open-source identity, authentication and authorization components for engineering teams that want to assemble their identity layer from parts. It fits organizations that have a platform team and treat identity as core infrastructure, not as a feature bought from a vendor.
The cost is ownership. Integration, upgrades and incident response sit with your engineers. For a small product team without that capacity, a managed service is usually the safer starting point. Pricing information is on request for the commercial offerings.
Zitadel
Zitadel offers identity management, authentication and organization-level access control with open-source options. Teams that want an open codebase and the freedom to host it themselves, or to use a managed deployment later, find it a useful middle path.
When self-managed, hosting and governance take more effort than with a fully managed product. Check how backups, key management and tenant administration are handled in your chosen deployment model before committing. Pricing is on request.
Ping Identity
Ping Identity serves large enterprises whose customer access needs involve complex authorization, many partner relationships and strict governance. For a SaaS company selling into very large organizations, it may be the platform those customers already know, and that familiarity can matter in procurement.
Enterprise architecture and implementation can be substantial, and the project usually needs dedicated identity engineers rather than a part-time owner. For a company at an earlier stage, this scale of platform is rarely the first step. Pricing is on request and is typically scoped with a sales team.
Authgear
Authgear provides authentication, single sign-on, multi-factor authentication and user management, with deployment options that allow self-hosting. It suits teams that want a hosted or self-hosted authentication service without building the whole stack.
Operations and security maintenance stay with your team when you self-host. Confirm which deployment model fits your data requirements before you build the integration, because moving identity data between hosting models later is slow. Pricing is on request.
Amazon Cognito
Amazon Cognito provides managed user pools, federation, authentication and authorization for applications. For a product already built on AWS, it keeps identity inside the same account structure, IAM model and billing relationship as the rest of the stack, which simplifies procurement and access reviews.
Configuration, the built-in login interface and the operational limits of user pools need testing against your own flows. Teams often find that custom sign-in journeys take more work than they expect. Check the current Cognito pricing page for the billing dimensions that apply to your user count and features.
Feature decision table
Use this table to narrow the list before running a trial. It names the common requirement and the kind of tool that usually meets it. Confirm each row against the vendor’s documentation, because feature sets change.
| If you need | Start with | Because |
|---|---|---|
| Enterprise SSO added to an existing login | WorkOS | Its public focus is SSO, directory sync and audit logs for B2B buyers |
| Hosted customer login matching your workforce provider | Okta | Same administrative model for customers who run Okta internally |
| Authentication built into your own app code | Auth0 | Developer-oriented tenant, token and flow control |
| Passwordless and fraud signals behind your own UI | Stytch | API-first authentication and fraud building blocks |
| Visual flow changes without a release each time | Descope | No-code flow building with API access for custom logic |
| Ready-made sign-in and organization switcher | Clerk | Prebuilt components and organization management for web apps |
| Data residency through self-hosting | FusionAuth, Authgear or Zitadel | Self-hosting options, with operations taken on by your team |
| Open-source components in a platform team | Ory | Modular open identity infrastructure |
| Complex enterprise customer access | Ping Identity | Enterprise-scale authorization and governance |
| Identity inside an existing AWS account | Amazon Cognito | Managed user pools within the AWS account and IAM model |
How to choose
Start with three questions. First, who will own identity after launch: a product engineer, a platform team, or nobody in particular? A tool that needs a platform team should not be chosen for a team of three. Second, does any customer contract require data to stay in a specific region or environment? If so, narrow the list to tools with a matching deployment option before comparing features. Third, what does the first enterprise deal need? If it needs SSO and directory sync within weeks, that requirement usually decides the order of work.
After those questions, run a trial on a single representative tenant rather than a demo account. Use a real customer domain for the SSO test, a real organization with several roles, and a deliberately removed user to check deprovisioning. Record how long each step takes and where the vendor documentation was unclear. Those notes will carry more weight in the decision than any feature list.
Setup and migration checklist
Moving customer identity is slower and riskier than moving most other tools, because existing sessions, password hashes and organization links all have to survive the change. The checklist below is a planning aid. Adapt it to the vendor’s own migration guidance and your data-protection obligations.
| Stage | Action | Done when |
|---|---|---|
| 1. Inventory | List every login method, session type, organization model and admin role in the current system | Each method has an owner and a documented fate |
| 2. Data mapping | Map user, organization and role fields to the new tool, and decide which identifiers are the source of truth | A written mapping has been reviewed by engineering and support |
| 3. Pilot | Move one internal tenant and one friendly customer through every flow, including recovery and deprovisioning | Pilot users complete sign-in, recovery and removal without manual intervention |
| 4. Session plan | Decide whether existing sessions are kept, forced to re-authenticate, or phased out | Customers have been told what to expect and support scripts exist |
| 5. Cutover | Switch in a planned window with rollback steps written down | Rollback has been rehearsed and the owner is on call |
| 6. Review | Compare login completion, support tickets and provisioning errors with the baseline from stage 1 | Metrics are reviewed at a set date after cutover |
Keep the audit trail continuous during the move. Enterprise customers will ask who changed access and when, and a gap in the logs during migration can delay a security review far longer than the migration itself.
Frequently asked questions
Which tool should a B2B SaaS team add first for enterprise SSO?
WorkOS is the most direct first candidate for many teams, because its public focus is SSO, directory sync and audit logs, which are the requirements enterprise buyers raise most often. Pricing is on request, so request a quote that includes the number of enterprise connections you expect in the first year.
Is customer identity the same as workforce identity?
No. Employees, contractors and your own customers have different lifecycles, approval paths and risks. Some platforms serve both, but you should confirm that one design does not make customer sign-up harder than it needs to be.
Should I self-host my identity service?
Self-hosting can be necessary when customer contracts require data to stay in a specific environment. It also moves patching, backups, scaling and upgrades onto your team. If no contract requires it, a managed service is usually the lower-risk choice for a small team.
How do I compare prices between identity vendors?
Ask each vendor to price the same scenario in writing: monthly active users, number of organizations, enterprise connections, authentications and support tier. Compare totals for that scenario rather than list figures that use different billing units.
What breaks most often during an identity migration?
Usually it is session handling, password or credential transfer, and organization links that were modeled differently in the old system. Map those three areas first, and pilot account recovery and deprovisioning before any production cutover.
Does an identity tool make my product secure by itself?
No. The security of the result depends on the flows you configure, the protocols you enable, how you handle recovery and tenant boundaries, and how you monitor the audit log. A vendor can provide the controls, but your team still has to use them correctly.
Where should identity sit in our security review?
Treat it as a core system with its own owner, threat model and change process. Review it alongside your wider security program, and read the related guides on security tools and data governance before deciding who owns which control.
