A Chennai bank’s call-centre had a chronic problem: agents shared passwords because typing the 16-character compliance-required password 80 times a shift was painful. After deploying YubiKey FIDO2 authenticators, the same agents tapped a hardware key, hit a PIN, and were in. Help-desk tickets dropped 71%, phishing-related credential compromises went to zero, and agents stopped sharing keys (because they’re physical and you don’t share your house key). Passwordless isn’t aspirational — it is shipping in 2026 production. This module covers FIDO2 / passkeys end-to-end.
Why passwordless
Passwords have inherent weaknesses no security awareness training fixes:
- Phishable — a fake login page steals them
- Reusable — one breach contaminates many sites
- Forgettable — drives password reset support load
- Shareable — frictionless to give away
- MFA-bypassable — push fatigue, MFA-prompt bombing, SIM swap, OTP phishing
FIDO2 + passkeys solve all of these by binding authentication to a private key the user can never type, never share, and that’s bound to the legitimate origin.
