Problem
Security keys are registered but no spare key is stored in a secure offline location.
Solution
Root Cause / Diagnostic:
Hardware security keys (FIDO2 / WebAuthn) provide the highest tier of phishing resistance, but registering only one physical key introduces catastrophic single-point hardware failure risk. If that key is lost, crushed, or damaged, the user faces severe Google account recovery hurdles.
Actionable Fix:
1. Dual Security Key Pairing: Always register a minimum of two identical hardware security keys (e.g., YubiKey 5C NFC) to the Google account simultaneously.
2. Safe Enclave Key Storage: Keep the primary key on your daily keychain or workstation, and place the spare backup key inside a fireproof, locked home safe.
3. Multi-Key Registration Verification: Check Google Account > Security > 2-Step Verification to confirm that both primary and secondary security keys are registered and labeled accurately.
Pro Tip:
When buying hardware keys like YubiKeys, always buy two at the same time. Register both to your Google account, put one on your keychain, and lock the second one in a safe as your unbreakable backup.
