Why Passwords and SMS 2FA Fail under Attack
Account takeovers on centralized exchanges rarely stem from cryptographic breaches. They happen because passwords are leaked in external database breaches, and SMS 2FA is easily intercepted through SIM swaps. To protect your accounts, eliminate SMS authentication across all financial services.
The Phishing Proof Standard:
FIDO2/WebAuthn hardware keys use public-key cryptography tied directly to the browser's verified domain name. If you are tricked into visiting a fake exchange domain, the hardware key will not authenticate because the domain origin does not match.
Step-by-Step Security Key Setup
- Step 1: Purchase two identical FIDO2/U2F hardware keys (e. G., YubiKey 5 Series). One serves as your daily key, the other as an offline backup.
- Step 2: Log in to your exchange accounts (Binance, Coinbase, Kraken, Bybit) and navigate to Security Settings.
- Step 3: Register both hardware keys under 'Security Key' / 'FIDO2 / WebAuthn'.
- Step 4: Disable SMS 2FA and remove your phone number as an account recovery fallback method.
- Step 5: Store your backup hardware key in a secure, fireproof home safe.
