Microsoft says it will embrace decentralized identity systems based on Bitcoin and other public blockchains through the Microsoft Authenticator app
In a new post today, Microsoft announced their embrace of public blockchains, such as Bitcoin and Ethereum, for use in decentralized identity systems.
Context & Ripple Effects
This announcement is the consumer-facing turn in an identity program Microsoft has been assembling since 2016, when it began working with Blockstack Labs and ConsenSys on a blockchain-based ID framework slated for Azure. In between came the UN-backed personal ID network with Accenture aimed at people without official documents, showing Microsoft treating identity as infrastructure rather than a login feature.
What changes here is the delivery vehicle: instead of an enterprise cloud service, decentralized identifiers anchored to Bitcoin and Ethereum land inside Microsoft Authenticator — the same app Microsoft has been steadily upgrading into a password replacement, first with phone authentication and later full passwordless logins.
First-order effects
- Microsoft Authenticator users become the test population for self-sovereign IDs anchored to public blockchains, giving Bitcoin and Ethereum their first mainstream identity workload rather than a payments one.
- Blockstack Labs and ConsenSys gain distribution through a consumer app with hundreds of millions of potential touchpoints, converting their Azure-era developer framework into an end-user product surface.
Second-order effects
- Rival identity providers — Google and Apple above all — face pressure to answer with user-controlled credential support of their own, or cede the 'portable identity' framing to Microsoft.
- Enterprises running Azure Active Directory get a roadmap toward accepting externally verifiable credentials, which begins to pull partners and suppliers toward issuing compatible proofs rather than managing separate account provisioning.
Third-order effects
- If the pattern holds, account ownership migrates from provider-held databases to credentials users carry themselves, making the authenticator/wallet app the control point of digital identity — and interoperability standards, not any single company's directory, the competitive battleground.
- Public blockchains would settle on a role beyond value transfer: timestamping and anchoring identity state, which entrenches the chains with the strongest immutability guarantees regardless of token economics.
The trend: Platform companies are relocating digital identity from proprietary account databases onto public-blockchain-anchored credentials, with the authenticator app emerging as the user's point of control.
