Passkeys Explained — How They Kill Phishing, Vishing & Password Theft

Every breach in our last episode died the same way it started — with a password. So this week: the fix that's finally winning. On World Passkey Day this May, the FIDO Alliance counted 5 billion passkeys in use. The password isn't dead yet — but we finally have the thing that kills it. What you'll hear: • How a passkey works — public/private keypair, private key never leaves your device, origin-bound signatures • Why passkeys defeat the 2026 attack playbook — phishing, credential stuffing, MFA fatigue, and the help-desk reset scam (CISA advisory AA23-320A names FIDO as the fix) • The numbers — 98% vs 32% sign-in success, ~1M passkeys/day, Gartner's 2027 call • Synced vs device-bound passkeys — and why device-bound = NIST AAL3 • The honest half — account recovery, device loss, and the real 2026 frontier • Network+/Security+ relevance — phishing-resistant MFA, by the book Sources: FIDO Alliance (World Passkey Day 2026) · Microsoft Security · CISA/FBI advisory AA23-320A · NIST SP 800-63B. — Andrés Sarmiento #passkeys #cybersecurity #passwordless #FIDO2 #SecurityPlus #TechUpdates
