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.
