monipassinen

Monipassinen is a term used in speculative discussions of digital identity and in some science fiction works to denote a hypothetical single, portable credential that would grant access across multiple online services and physical locations. The name blends elements of Finnish language roots, such as mono meaning single and passinen related to pass or passport, to express the idea of a universal credential.

Conceptually, a monipassinen would function as a portable identity token issued by a trusted authority. It could be stored in a secure device or digital wallet and designed to enable authentication across different domains, with mechanisms for selective disclosure of attributes, revocation, and portability. Implementations in fiction often explore either centralized or decentralized governance models, and may incorporate cryptographic techniques such as verifiable credentials or zero-knowledge proofs to balance usability with privacy.

In discourse, monipassinen appears as a thought experiment used to illustrate both the potential benefits and the risks of universal identity systems. It is referenced in academic discussions about privacy, consent, and governance, as well as in science fiction to probe social and political implications of pervasive authentication.

Advantages commonly discussed include reduced credential fatigue for users and streamlined access control across services. Criticisms focus on security risks, single points of failure, potential for mass surveillance, governance complexity, and the challenge of achieving interoperability without compromising user privacy.
