LimenStart free
Signed DPA included on every paid plan

Authentication,
built in Europe.

Limen handles sign-in, MFA, API keys, and agent identity for EU teams that need GDPR by default — not by checkbox. Hosted in the EU, never anywhere else.

What you get

Three things we got tired of waiting for someone else to build.

GDPR is the default

Data stays in the EU because we run nowhere else. Signed DPA included on every paid plan, sub-processor list short and public, erasure and export built in.

EU · eu-central

Easy on purpose

One tenant, one console, readable docs and an OpenAPI spec. Built by engineers who got tired of fighting Okta and Auth0 to do simple things.

cURL → live in minutes

Ready for AI

First-class agent identity over MCP, scoped API keys, and machine-to-machine flows. Auth that understands half your users are not people.

MCP · API keys

Sovereignty by default

Your users' data does not leave the EU. Ever.

Limen runs on EU infrastructure, and only there. Backups are encrypted at rest in the same region that wrote them. No US parent company, no Schrems exposure, no quiet sub-processor in Virginia.

Capabilities

The auth you need. Nothing you didn't ask for.

Sign-in that works

Email and password hashed with Argon2id, plus Google sign-in — with tenant-configurable policy.

MFA

TOTP authenticator apps and email one-time codes, enforced or optional per tenant.

API keys

Scoped live and test keys for server-to-server calls, revocable from the console.

Audit log

Every auth event recorded, searchable in the console, and scoped to your tenant.

Agent identity

Connect Limen to Claude Desktop over MCP and drive scoped, read or write operations.

GDPR tooling

Right to erasure and JSON data export built in, with a 30-day grace period before hard delete.

Pricing

One number, no add-ons.

MFA, API keys, the audit log, and the signed DPA are in every paid tier.
