Senior LevelAuthentication & Authorization
What is the future trajectory of Authentication & Authorization (Universal Passkeys, Decentralized Identity, Agentic IAM)?
❓ Interview Prompt: Summarize the future evolution of identity systems: universal Passkeys, Decentralized Identity (DIDs/VCs), Agentic IAM, and Post-Quantum Security.
2026+ Identity & Security Engineering Trajectory:
1
Universal Passkey Adoption: Passkeys complete the elimination of legacy passwords, becoming the universal consumer and enterprise login default.
2
Decentralized Identity & Verifiable Credentials (W3C DIDs): Users control sovereign identity wallets, presenting cryptographically verifiable credentials (VCs) using Zero-Knowledge Proofs (ZKPs).
3
Agentic IAM & Machine Identity: Autonomous AI Agents possess dedicated short-lived cryptographic identities, tool access delegation scopes, and real-time execution boundaries.
4
Continuous Access Evaluation (CAEP / SSF): Real-time, event-driven identity revocation standard across all SaaS and cloud networks.
5
Post-Quantum Cryptography Migration: Transitioning key exchanges and digital signatures to NIST ML-KEM and ML-DSA lattice algorithms.

quantumDefense: 'NIST ML-KEM-768 + ML-DSA-65';
}💡2026+ Modern Enterprise Identity & Security Architecture stack.
🎯 Interview Key Takeaway
Future identity systems unite universal Passkeys, Graph ReBAC, SPIFFE workload identities, ZKPs, and Post-Quantum cryptography.
