Quick summary

KuCoin is a cryptocurrency exchange where users sign up with an email or phone number, sign in via its login page, and then use optional security layers such as Google Authenticator (2FA), phone binding, and an anti-phishing code to protect their account.

Signing up & logging in (high level)

  • You can register with an email address or a phone number and create a password.
  • For login, KuCoin presents forms for Email/Phone and may support modern methods such as passkeys and 2-step verification.
  • After credentials, a second factor (SMS or authenticator code) is commonly required for sensitive actions.

Security features you should know

  • Two-Factor Authentication (2FA): Use an authenticator app (e.g., Google Authenticator) rather than SMS when possible — it’s more secure and time-based codes refresh every 30 seconds.
  • Anti-Phishing Code: A safety phrase shown on official emails to help you identify legitimate messages from the exchange.
  • Password hygiene: Use a unique, strong password and consider a hardware or software password manager.
  • Account binding: Link and secure your phone and email accounts — enable 2FA for your email too.

Common login snags & mitigation

“If your authenticator code fails, check that the app time is synced and that you’re using the code for the correct account.”

  • Authenticator apps generate short-lived codes — ensure device time is correct.
  • Keep backup codes in a secure place (offline) so you can regain access if you lose your phone.
  • Never share verification codes or your anti-phishing code with anyone claiming to be support.

Bitcoin — a short, friendly primer

Bitcoin is a decentralized digital currency that runs on a public ledger called the blockchain. Transactions are broadcast to the network and miners/validators bundle and confirm them in blocks. Bitcoin is managed by cryptographic keys: a public address for receiving and a private key for signing transactions. If you control the private key, you control the funds — so safeguarding keys is essential.

Practical safety tips for Bitcoin holders

  • For long-term holdings, consider using cold storage (hardware wallets) rather than leaving large balances on exchanges.
  • Use multi-factor protection for exchange accounts and withdraw to self-custody if you need full control.
  • Understand transaction fees and confirmations; time-sensitive payments may require higher fees for faster inclusion.
