About Us

We are a global and remote team who believes that privacy matters in technology.

Our Name

“Least Authority” is derived from “the principle of least authority” (PoLA) — also known in information security as “the principle of least privilege” or “the principle of minimal privilege” — a security best practice requiring system components to only have the privilege necessary to complete their intended function and not more.

Our History

Least Authority was formed in the U.S. in 2011 to create freedom-compatible technologies. Since then, we have been working on decentralized systems (sometimes referred to as Web3) and began our security auditing work in 2014. The following year, a report we did for Ethereum identified the issues that lead to the DAO hack. In 2016, the company relocated to Berlin with Liz Steininger as CEO / Managing Director.

Our Mission

Least Authority is committed to building and supporting the development of usable technology solutions and ethical business practices to advance digital security and preserve privacy as a fundamental human right. We do this through:

Security Consulting

Conducting security audits and providing consulting services for software development projects, especially within Free and Open Source Software (FOSS) communities. This allows us to advance the security of systems and contribute to the community of developers who build them (see published audits).

Product Development

Building products with a specific focus on increasing the security of the data and systems, along with enhancing and preserving privacy. We build on open source software to expand the access to them and provide sustainability that is built on ethical business models.

Community Matters

We develop free and open source software (FOSS) and engage with and contribute to various communities (human rights organization, NGOs, privacy activists) to promote the use of secure systems and privacy-protecting technology, including zero-knowledge proofs.

We prioritize security and try to avoid only security by policy.


We prioritize users’ privacy and try to avoid only privacy by policy.
