Add login, social login and SSO to your app without building them from scratch
LoginMaster is a European authentication-as-a-service: login, registration, social login, MFA and enterprise SSO ready to integrate over open standards, with identity data in your Tenant in the European Union.
In short
LoginMaster is a European authentication-as-a-service: add login, registration, social login, multi-factor authentication (MFA) and enterprise SSO to your application or SaaS via OAuth 2.0, OpenID Connect and SAML 2.0, without building and maintaining them from scratch. It is GDPR- and NIS2-compliant by design, and users' identity data stays in your Tenant in the European Union — nobody, not even LoginMaster, can access the credentials.
Everything you add with a single integration
Login, social login, SSO, MFA and provisioning ready to use, instead of authentication flows to build and maintain in-house.
Login and registration
Ready-to-use, white-label login, registration, email verification and password recovery pages, without building the flows from scratch.
Social login
Sign-in with social and business providers (Google, Microsoft) via OAuth 2.0 and OpenID Connect, configurable per project.
Enterprise SSO
Federated Single Sign-On with Google Workspace and Microsoft Entra ID via SAML 2.0 and OIDC: employees sign in with the credentials they already use.
MFA and 2FA
TOTP multi-factor authentication configurable per project (optional, mandatory or per role) and not disableable by administrators.
Provisioning and webhooks
Create, update and disable users via REST API and TypeScript/.NET SDKs; webhooks notify lifecycle events in real time.
Ready-to-use JWT tokens
LoginMaster issues JWT tokens signed with user and tenant claims: your app verifies the signature and applies its own authorization logic.
GDPR-compliant authentication-as-a-service, with data in the EU
Unlike US platforms, LoginMaster keeps identities and credentials in Europe and has no access to users' passwords.
Data in your EU Tenant
Identities and credentials stay in your Tenant in the European Union; the Cloud operates only on encrypted, pseudonymized data, with European data residency.
Zero-knowledge on credentials
Passwords are not accessible to anyone — not to you, not to LoginMaster: it is not a policy, it is an architectural constraint. No function can return or reset a user's password on their behalf.
GDPR and NIS2 by design
Cryptographic isolation between tenants, configurable mandatory MFA, audit logs and audit-ready ISO 27001 documentation to answer compliance questionnaires with technical evidence.
The European alternative to Auth0, Cognito and Firebase
If you are evaluating how to add authentication to your app, LoginMaster offers the same feature set as the US platforms — login, social login, SSO, MFA — but with EU data sovereignty, unlimited users and compliance by design. Compare LoginMaster with:
How you integrate it in three steps
From your app to production without building and maintaining authentication infrastructure.
Connect your app via OIDC/OAuth
Register your application and connect it to LoginMaster with standard OAuth 2.0 and OpenID Connect flows (or SAML 2.0), without proprietary SDKs.
Enable login, social login, SSO and MFA
Turn on the sign-in methods you need from the console and brand the pages with your own identity, per tenant.
Receive tokens and go live
Your app receives signed JWT tokens and lifecycle webhooks: no authentication infrastructure to maintain.
Frequently asked questions
You integrate LoginMaster via OAuth 2.0, OpenID Connect or SAML 2.0 and enable login, registration, social login (Google, Microsoft), MFA and enterprise SSO from the console. The pages are white-label and the JWT tokens integrate with any stack, without building and maintaining authentication in-house.
LoginMaster is a European authentication-as-a-service in which identity data stays in your Tenant in the European Union, credentials are not accessible to anyone (zero-knowledge), and GDPR and NIS2 compliance is by design, with audit-ready documentation.
The feature set is similar (login, social login, SSO, MFA), but LoginMaster is European: data in your EU Tenant, unlimited users instead of per-active-user (MAU) billing, and GDPR/NIS2 compliance by design.
Yes. Social login and federated SSO with Google Workspace and Microsoft Entra ID via OAuth 2.0, OpenID Connect and SAML 2.0, configurable per project.
No, not deeply. Any app that supports OAuth 2.0 and OpenID Connect — the majority of modern web and mobile frameworks — integrates without architectural changes: the app verifies the JWT token signature and uses the claims for its own authorization.
LoginMaster uses a per-tenant/project license with unlimited users included: the cost stays predictable as you grow, without the per-active-user (MAU) billing typical of AWS Cognito and Firebase.
