Why secure sign-in matters

Your KuCoin account controls trading access, balances, and (potentially) API keys that can move funds or trade programmatically. A compromised sign-in can mean lost assets, unauthorized trading, or data exposure. Protecting the sign-in process means hardening passwords, enabling robust multi-factor authentication, keeping devices safe, recognizing phishing, and preparing recovery steps. Together these practices greatly reduce the chance an attacker can gain access.

1. Use a password manager and unique passwords

Create a single, unique password for KuCoin using a password manager. Choose length over memorability — 16+ characters with mixed types is ideal. Let the manager autofill only on verified pages; don’t paste passwords into unfamiliar prompts. Avoid reusing passwords across exchanges, email accounts, or trading APIs.

2. Two-factor authentication (2FA): prefer apps and hardware

Enable an authenticator app (TOTP) rather than SMS-based codes to mitigate SIM-swap attacks. For the strongest protection, use a hardware security key (U2F/WebAuthn) where supported — it prevents phishing and forces physical presence. Always store recovery/backup codes securely offline in a safe place.

3. Verify domains and avoid phishing

Always reach KuCoin via a bookmark you created or by typing the known domain into your browser. Don’t click links in unsolicited emails or social messages. Confirm the browser’s padlock and domain, and be suspicious of typosquatted sites. If an email urges immediate login, pause and verify the message through your saved support channels.

4. Device hygiene and dedicated profiles

Sign in from devices you control. Keep OS, browser, and security tools updated. Use a dedicated browser profile for trading sites with minimal extensions enabled. Consider using a separate machine or sandboxed profile for high-value accounts to reduce cross-site risk.

5. API keys, session management & recovery planning

When creating API keys, restrict IPs and scopes (read-only vs trade/withdraw). Periodically review active sessions and authorized apps and promptly revoke anything unfamiliar. Store recovery steps and backup codes offline, and document an incident plan: freeze activity, rotate keys, contact support, and provide evidence timelines.
