Analyst Chat #285: Future-Proofing Authentication in a Post-Quantum World
Mon Feb 02 2026
Quantum computing isn’t just a future threat to encryption, it’s a direct risk to identity and authentication. In this week's episode, Matthias is joined by Jonathan Care to explore why identity is the quantum bullseye and what organizations must do now to prepare for a post-quantum world.
You’ll learn:
✅ Why authentication protocols depend entirely on cryptography
✅ How “harvest now, decrypt later” (HNDL) already puts identity data at risk
✅ Why identity, not data encryption, is the weakest point in a quantum future
✅ What post-quantum cryptography standards (FIPS 203, 204, 205) change — and what they don’t
✅ How Passkeys and FIDO2 are quietly becoming post-quantum ready
✅ Why PKI, certificates, federation, and non-human identities face massive scale challenges
✅ What crypto agility really means for IAM and Zero Trust
✅ A practical 4-phase roadmap for CISOs to start preparing today
The biggest risk isn’t a future quantum computer — it’s the long-lived certificates and identity data issued today.
