There’s a quiet philosophical change happening in how software systems think about the people using them. For most of computing’s history, the assumption was simple: identify yourself, then get access. But that default is eroding, and not because of any single decision. It’s the accumulated result of years of design choices that prioritize function over identity.
Linux has always been the clearest example. Install any major distribution today, and you’ll encounter zero mandatory identity checks. No account linked to a phone number. No government ID. Just a username you invented five minutes ago and a password. That design philosophy, anonymous by default, was once considered a quirk of open-source culture. Increasingly, it looks like a template.
Why have OS setup screens stopped asking who you are
The transition away from identity-linked setup flows started with a practical problem: verification creates friction, and friction drives users away. Early versions of Windows and macOS tied activation to hardware fingerprints and product keys, but neither actually confirmed human identity. Over time, optional cloud accounts replaced mandatory registration, and many users simply skipped them entirely.
What drove this further was developer pressure. Distributing software through curated stores meant the platform, not the individual app, handled authentication. The app itself no longer needed to know who you were, only whether you had a valid install. That separation quietly removed identity from the core OS experience.
How sandboxing replaced trust-based identity models
Sandboxed environments, think macOS app containers or Flatpak on Linux, operate on a different logic entirely. Instead of trusting a user’s identity, the system trusts nothing by default and grants access only to explicitly declared resources. It’s a permission model, not an identity model. The difference matters enormously in practice.
This same logic has spread well beyond desktop software. Platforms built around pseudonymous or permissionless access now span everything from developer APIs to financial tools.
No KYC Casinos, for example, are one visible example in the online casino space, where operators have adopted the same permissionless-access philosophy. Using blockchain and crypto’s decentralised nature, these online platforms are validating capability rather than identity. It’s similar to how sandboxed apps request only what they need, without requiring the user to prove who they are first.
Where anonymous access is spreading beyond computing
The irony is that this drift toward anonymous-by-default design is now colliding with serious legislative pushback. A bipartisan US House bill introduced in April 2026 would require OS providers running Windows, macOS, and Linux distributions to verify every user’s age at setup. California has already moved separately, mandating that OS providers collect age data and share categorized results with apps.
Privacy researchers have flagged real concerns here. Moving verification into the OS layer hands an extraordinary amount of user data to a small number of platform companies, Apple, Google, and Microsoft, whose decisions then affect billions of people. The Proton blog analysis from 2026 outlines how this concentration of identity infrastructure creates systemic privacy risks that app-level verification never could.
What this means for software design going forward
The tension between these two directions, systems engineered to know less about you versus legislation demanding they know more, is going to define OS development through the rest of this decade.
Developers building on Linux or creating cross-platform apps will increasingly need to architect around compliance requirements that sit at the OS level, not the application level. That’s a significant structural change.
What’s clear is that “identity-lite” design was never ideological for most engineers; it was simply practical. Age attestation meant fewer identity dependencies mean fewer failure points, fewer regulatory surface areas, and faster deployment.
Whether that practical advantage survives the current legislative moment is an open question. But the underlying logic isn’t going away, and the platforms that figure out how to satisfy compliance demands without centralizing identity data will have a meaningful architectural edge.
