LinOTP: sovereignty score and 8 European alternatives

LinOTP is an open-source one-time password solution for two-factor and multi-factor authentication. It is offered as a turnkey virtual appliance for operation on an organisation's own infrastructure, and the vendor also refers to a LinOTP Cloud option alongside enterprise support. The software is licensed under AGPLv3 and GPLv2, so the organisation can inspect and run the source code itself.

LinOTP is developed by netgo software GmbH, with its registered office in Berlin, Germany. Because the company is German and the software can run on an organisation's own servers, authentication data can stay under European jurisdiction. The vendor's website does not state where LinOTP Cloud hosts data, and its privacy statement describes netgo's own websites and services. European buyers should therefore request the hosting location and a data processing agreement for any cloud service.

Why digital sovereignty matters with LinOTP

LinOTP is headquartered in DE and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so LinOTP scores best on data residency.

LinOTP is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

What this means for your organisation depends on your whole stack and context. The free assessment weighs LinOTP together with your other vendors and gives a total score, a heatmap and the main risk drivers.
