KuCoin® — Clean Guide & Fresh Style

Start here — the quick snapshot

If you only have two minutes, do these: (1) enable MFA (prefer hardware or authenticator), (2) secure your email with MFA, (3) set a strong unique password (use a password manager), (4) enable withdrawal whitelist and a withdrawal delay. This minimal set reduces most account-takeover risks.

Fresh setup — step by step

1. Confirm domain and app source. Use bookmarks and official app stores; never paste credentials from unknown links.
2. Create a unique password. Use a password manager and a long, randomly generated string or passphrase.
3. Enable MFA. Register a hardware key (WebAuthn/U2F) if you have one; otherwise use an authenticator app (TOTP). Keep backup codes offline.
4. Secure email first. The email tied to your exchange account is the recovery anchor—protect it with MFA and unique credentials.
5. Set withdrawal protection. Enable address whitelisting and withdrawal delays where possible.

Why this order? Compromised email or phone often becomes the weakest link. Secure the recovery channel before adding exchange protections.

Multi-factor authentication — modern choices

MFA reduces risk drastically. Here’s a practical ranking:

• Hardware security keys (WebAuthn/U2F): Highest protection; phishing-resistant and recommended for high-value accounts.
• Authenticator apps (TOTP): Strong and convenient—Authy, Google Authenticator, or hardware TOTP devices are good options. Make a secure backup of the seed.
• SMS / phone codes: Better than nothing but susceptible to SIM swaps—use only if stronger options are unavailable.

Tip: Register two factors (e.g., a hardware key + TOTP) so you have an immediate fallback without calling support.

APIs, bots, and third-party tools

If you automate trading, treat API keys like credentials. Follow least privilege and lifecycle practices:

• Give each service its own API key; do not reuse keys across tools.
• Restrict permissions — use read-only keys for analytics and trading-only keys for bots; avoid enabling withdrawals unless absolutely required.
• Use IP whitelisting when supported and rotate keys regularly.
• Vendor vetting — choose reputable bot providers and prefer open-source or auditable solutions.

Withdrawal safety & custody separation

Withdrawals move value out of your control; apply friction:

• Whitelist trusted addresses and avoid approving new addresses while stressed or rushed.
• Enable withdrawal delays (e.g., 24–72 hours) for first-time or recent-address withdrawals to create a reaction window.
• Keep large balances in cold storage or split funds: operational balance on exchange, bulk reserves offline.

For sensitive assets, combine whitelisting with manual multi-person approval processes where possible.

Device hygiene — practical checklist

• Keep OS, apps, and browser up to date.
• Limit browser extensions — remove unnecessary ones.
• Use full-disk encryption on laptops and strong PIN/biometric on phones.
• Use a reputable VPN when on untrusted networks; prefer your mobile data over café Wi-Fi.

Incident playbook — what to do if something looks wrong

1. Change your exchange password immediately and sign out of other sessions.
2. Revoke all active API keys and rotate secrets.
3. Disable withdrawals if the exchange supports it; enable address freeze if available.
4. Secure linked email (change password, enable MFA) and check its account activity.
5. Contact KuCoin support through verified channels; prepare to provide account verification documents if requested.

Privacy and operational notes

Exchanges see metadata: which addresses you check, which markets you watch, and sometimes IP/location. If privacy matters, consider:

• Using different accounts for distinct strategies or jurisdictions.
• Running your own node or a trusted relay when supported to reduce third-party scanning of addresses.
• Minimizing address reuse and preferring fresh deposit addresses where possible.
