What is AutheoID and how do developers integrate it?

AutheoID is a core Autheo protocol component — not a third-party integration — built by the same team that designed the network's consensus and cryptographic architecture.

Direct Answer

AutheoID is Autheo's post-quantum sovereign identity layer, giving users a single portable digital identity across all applications built on the Autheo network. Developers integrate it via the Autheo SDK using standard OIDC/OAuth patterns for authentication, with selective disclosure for privacy-preserving data sharing — secured by CRYSTALS-Dilithium signatures instead of traditional ECDSA.

What AutheoID Provides

AutheoID gives every Autheo user a self-custodied identity anchored on-chain. Unlike traditional email/password or even Web3 wallet-based login, AutheoID supports: (1) cross-application portability — one identity that works across all Autheo dApps; (2) selective disclosure — users share only the identity attributes each app needs; (3) post-quantum cryptographic signatures using CRYSTALS-Dilithium; and (4) zero-knowledge proof support for privacy-preserving age, credential, and access verification.

Integration Guide Overview

Integrating AutheoID is designed to feel familiar for developers who have used OAuth2 or OIDC before. The Autheo SDK exposes `AutheoID.authenticate()` and `AutheoID.getProfile()` methods with a standard token-based flow. For server-side apps, the SDK provides a JWT validator that checks Autheo's on-chain identity registry. Full integration documentation, code samples, and a sandbox environment are available at docs.autheo.com/autheoid.

Post-Quantum Protection for User Identity

Traditional web identity is protected by ECDSA (secp256k1 or P-256), which is vulnerable to Shor's algorithm on a sufficiently powerful quantum computer. AutheoID uses CRYSTALS-Dilithium, a NIST-selected post-quantum signature scheme, meaning user identities are protected against both current and future cryptographic attacks. Developers building on AutheoID inherit this protection without any additional cryptographic implementation.

Portable across all Autheo apps

A single AutheoID works seamlessly across every application deployed on the Autheo network — eliminating identity fragmentation for users and developers.

Expert Perspective

“
Post-quantum cryptography is not a future concern — it is a present architectural decision. Systems designed today with classical cryptography will need to be re-engineered or replaced as quantum computing matures.
