B2B identity layer for multi-tenant SaaS
LoginMaster is the multi-tenant identity layer for B2B SaaS companies: give your customers white-label login, enterprise SSO and self-service user management, while each organization's data stays isolated with dedicated cryptographic keys. A European alternative to Frontegg and Ory, compliant with GDPR and NIS2.
What is a B2B multi-tenant identity layer
In a B2B SaaS, every customer is an organization (tenant) with its own users, roles, security policies and branding. A multi-tenant identity layer handles this complexity for you: organization sign-up and onboarding, invitations, per-tenant roles, SSO with each customer's IdP and strict data separation between one tenant and another.
Instead of building and maintaining authentication, organization management and federation in-house, you integrate LoginMaster via SDKs and REST API. Unlike US providers such as Frontegg, Auth0 and Ory, LoginMaster's Tenant-Cloud architecture means personal data never leaves the customer's tenant: the Cloud operates only on encrypted and pseudonymized data, with full European data sovereignty.
Multi-tenant by design
Every customer is an isolated tenant with independent users, projects, roles and configurations. Add new organizations without touching existing ones and without bottlenecks.
White-label for your customers
Login pages, emails and authentication flows customizable with each tenant's brand. Your customers get an experience consistent with your SaaS, not with a third-party provider.
Cryptographic isolation
Dedicated keys per tenant and project: one customer's data is never accessible to another. The compromise of one tenant does not propagate and personal data stays on the tenant.
Everything a B2B SaaS needs
The platform pillars cover the entire multi-tenant identity lifecycle, from end-user login to administration of customer organizations.
White-label authentication
Brandable login pages, transactional emails and 2FA flows per tenant. Give your customers an authentication experience that feels like a native part of your product.
Cryptographic per-tenant isolation
Each customer organization has unique cryptographic keys. Personal data never leaves the tenant: the Cloud operates only on encrypted and pseudonymized data, not even the provider can access it.
SSO and enterprise login
Federation with Google Workspace and Microsoft Entra ID to give enterprise customers SSO with their own IdP. Reduce passwords and enforce consistent identity policies on every tenant.
Organization self-service
Customers manage their own users, invitations and organization settings, while no administrator can alter credentials or 2FA on behalf of a user. Less load on your support team.
Per-tenant roles and RBAC
Define roles and permissions per project and per tenant, enforcing least privilege. Each organization configures its own access policies without interfering with the others.
Integration via SDK and REST API
TypeScript and .NET SDKs, REST API and dual-signature tokens to integrate the identity layer into your SaaS in days, not months. Security events ready for your SIEM.

B2B IAM for SaaS frequently asked questions
It is the component that handles identity and access for a SaaS where every customer is an organization (tenant) with its own users, roles and policies. It manages organization onboarding, invitations, SSO, per-tenant roles and data isolation between customers, so you don't have to build this logic in-house.
LoginMaster is a European alternative with a Tenant-Cloud architecture: personal data never leaves the customer's tenant and the Cloud operates only on encrypted and pseudonymized data. It offers white-label, cryptographic per-tenant isolation, SSO and per-tenant pricing with no cost per user, with GDPR and NIS2 compliance by design.
