Multifactor

Freemium

Secure platform for trustless account sharing, authentication, authorization, and auditing between humans and AI agents.

Key features

  • Trustless Authentication & Authorization: Provides cryptography-first mechanisms to grant and verify access to online accounts without relying on shared plaintext credentials, enabling scoped and auditable access for humans and agents.
  • Enclave Attestation Verification (Trust Center): An open-source trust-center component and SDK that verifies hardware enclave attestation documents (CBOR/X.509) and can generate enclave secrets for secure secret provisioning.
  • Multi-Factor Key Derivation (MFKDF): Reference implementations (Rust, JavaScript) of a next-generation multi-factor key derivation function to bind secrets to multiple authenticators or factors, improving resilience and recoverability.
  • Deterministic Password & Secret Tools: Tools such as a Multi-Factor Deterministic Password Generator (MFDPG) and a demo centralized password-management application to produce reproducible, multi-factor protected credentials.
  • Developer SDKs & Offline Verification: SDKs enabling programmatic parsing and validation of attestation documents locally (no network dependency), suitable for embedding in apps and CI systems for automated trust checks.
  • Open Source Reference Implementations: Public GitHub repositories with reference code (MFKDF2, trust-center, demos) to enable auditability, customization, and integration into bespoke security workflows.
  • Trust Center to verify hardware enclave attestations and generate enclave secrets
  • Reference implementations of Multi-Factor Key Derivation Function (MFKDF) in JavaScript and Rust
  • Multi-Factor Deterministic Password Generator (MFDPG) and centralized password management demo
  • Reference custodial and self-custody wallet implementations using MFKDF
  • Open-source SDKs and demo code distributed via npm and embeddable script tags
  • Trust-center can be run offline and is hosted as auditable GitHub Pages content
  • Certificate validation in SDK uses crypto.X509Certificate (Node.js >= 15.6.0 required)
  • Support for programmatic attestation verification workflows (CBOR attestation document parsing)

Best for

  • Secure Agent Credentialing: Provision short-lived, auditable credentials to AI agents running in trusted enclaves after automated verification of enclave attestations.
  • Contractor and Vendor Access: Grant scoped, time-limited access to SaaS accounts for contractors or vendors with full authorization controls and audit trails instead of sharing static passwords.
  • Encrypted Secret Injection in CI/CD: Validate runner or enclave attestation in build pipelines and inject secrets only to verified execution environments to reduce risk of secret exposure.
  • MFKDF-Based Wallets and Recovery: Build wallets or custodial/self-custody solutions that use multi-factor key derivation to bind private keys to multiple recovery factors and devices.
  • Deterministic Password Management: Generate deterministic, multi-factor protected passwords for accounts to avoid storing plaintext credentials while enabling recoverability.
  • Compliance & Audit Reporting: Maintain cryptographic audit logs of who/what (human or agent) accessed which accounts and when, supporting security reviews and compliance needs.
  • Securely share account credentials with human collaborators and automated agents while retaining auditability
  • Verify hardware enclave attestations before provisioning secrets to remote enclaves
  • Generate enclave-bound secrets for confidential compute workflows
  • Integrate MFKDF into wallet applications for multi-factor key derivation (custodial and self-custody)
  • Implement deterministic password generation and centralized password management demos for teams

Paid

Turns a smartphone video of an open trench into a centimetre-accurate 3D point cloud, CAD as-built plan and GIS-ready digital twin of buried utilities.

Key features

  • Smartphone capture: Field crews record an open trench with a standard iPhone Pro — no specialist scanning hardware and no separate surveying appointment
  • Centimetre-accurate point clouds: Reconstruction algorithms developed at ETH Zurich build a high-resolution 3D point cloud of the excavation from the video alone
  • Standards-compliant CAD output: Generates as-built plans in DWG and DXF, with couplings and pipe runs identified and measurements simplified
  • 3D digital twin and GIS export: Produces a model of the pipe route including building entries that drops into existing GIS systems
  • Works without GPS: Captures basement sections and building entry points where GNSS-based surveying fails
  • Immediate backfilling: Because capture takes minutes, trenches close right after filming instead of waiting on a survey crew
  • Documentation in about 72 hours: Complete records arrive weeks earlier than conventional surveying, enabling prompt connection billing
  • Third-party utility capture: Records crossing utilities and as-laid geometry as unbroken 3D evidence, replacing hand sketches

Best for

  • A utility network operator documenting residential service connections without booking a surveyor for every site
  • A contractor closing a trench the same day instead of leaving it open pending a survey appointment
  • Capturing a building entry point in a basement where GPS-based surveying cannot get a fix
  • A district heating project producing as-built DWG plans for regulatory sign-off
  • Spotting a laying error in the 3D point cloud before backfilling, while the fix is still cheap
  • Feeding as-built pipe geometry into a GIS system for long-term network maintenance planning
