Yubikey 5

Yubico's YubiKey 5 is the gold standard for phishing-resistant MFA, having proven its mettle when Google mandated hardware keys for all 85,000 employees and achieved zero successful phishing attacks over two years. This FIDO2/WebAuthn key, adopted by Apple, Google, and Microsoft, replaces SMS-based 2FA entirely—a critical upgrade given that SIM-swapping attacks bypass SMS trivially. Outperforming #10's software-only defense, the YubiKey 5 provides a physical barrier that no remote exploit can penetrate, with each key costing around $50 for unmatched protection against credential theft.
