Overview

Accessing your cryptocurrency account securely is critical. This guide focuses on general security best practices for logging into KuCoin (or any exchange). It covers how to prepare before login, the correct steps to authenticate, how to set up multi-factor authentication (2FA), how to recognize phishing, and what to do if you lose access.

Step-by-step login checklist

Before you begin

  • Ensure you are visiting the official exchange URL you trust: type it manually or use a saved browser bookmark.
  • Use a browser updated to the latest release and keep your OS patched.
  • Avoid public Wi-Fi; prefer your mobile data or a trusted private network when signing in.

Secure login flow

  1. Navigate to the official site via a bookmark or official mobile app. Do not follow email links unless verified.
  2. Check the browser lock icon and certificate (HTTPS) before entering credentials.
  3. Enter your email/username and password. Use a password manager to paste complex passwords instead of typing them.
  4. Complete 2FA — typically an authenticator app (TOTP) or SMS/phone verification if enabled.
  5. Confirm any new device or IP prompts only if you initiated the login.
Tip: Prefer an authenticator app (Google Authenticator, Authy, or similar) over SMS for stronger protection.

Session hygiene

  • Enable device management and review active sessions in account settings.
  • Log out when finished, especially on shared devices.
  • Use strong, unique passwords and a reputable password manager.

Setting up and using Two-Factor Authentication (2FA)

Two-factor authentication adds a second factor to the password. Recommended options:

  • Authenticator apps (TOTP): Most secure. Store your seed in a secure place. Consider an encrypted backup.
  • Hardware keys (U2F/WebAuthn): Best-in-class if supported — physical keys such as YubiKey provide strong protection.
  • SMS/phone: Better than nothing but vulnerable to SIM swap attacks — use only if no alternative is available.

Recovery codes

When enabling 2FA, save recovery codes offline — store them in an encrypted password manager or on paper in a safe place. Losing 2FA without recovery codes can create lengthy account recovery processes.

Recognizing phishing and scam attempts

Fraudsters often use fake websites, misleading emails, or social engineering to steal credentials. To defend yourself:

  • Never enter credentials on pages reached from unsolicited email links; navigate manually via bookmark.
  • Check domain spelling — small typos or extra words usually indicate a fake site.
  • Beware of urgent-sounding messages asking you to log in or "verify" details; verify via the official app or support channels first.
  • Support teams will never ask for your password or full 2FA code — if someone asks, it’s a scam.

Troubleshooting & account recovery

Common problems

  • Forgot password: Use the official password reset flow (email link expiry times are short — check spam folder).
  • Lost 2FA device: Use saved recovery codes or follow the exchange's official account recovery steps; prepare ID verification if requested.
  • Unable to receive SMS: Check carrier status, roaming settings, and SIM swap activity; consider switching to authenticator or hardware key.

When to contact support

Only contact support through the official site/app. Provide the minimum required information and avoid sharing sensitive secrets. If your account shows unauthorized activity, report it immediately and freeze withdrawals if possible.

Best practices summary

  • Use a password manager and unique passwords for every account.
  • Enable 2FA (authenticator or hardware key preferred).
  • Bookmark the official site; never use links from unsolicited messages.
  • Be cautious with browser extensions; only install trusted ones.
  • Keep backups of recovery codes securely and offline.
