Enable Two-Factor Authentication
Use an authenticator app (TOTP) rather than SMS when possible — it’s more secure against SIM-swap attacks.
Strong Unique Passwords
Use a password manager to create and store a unique password for your exchange account.
Device Hygiene
Keep your phone and computer updated, use reputable antivirus, and avoid public or shared devices for account access.
Watch for Phishing
Never enter credentials or 2FA codes on pages reached from unsolicited email links. Verify sender addresses and phone numbers.
Extra Precautions
Review and revoke API keys or connected apps you no longer use, enable withdrawal whitelists if KuCoin supports them, and monitor account activity regularly.
