KuCoin uses a separate six-digit Trading Password to authorize sensitive actions after login. It is not the account password, Google Authenticator code, email code or passkey. Confusing these credentials can block a trade, withdrawal or API action; changing security settings can also trigger an intentional 24-hour withdrawal restriction. This guide explains setup, verification, recovery and safe troubleshooting without exposing the secret to fake support.

1. What the KuCoin Trading Password is
It is a six-digit numeric password used to confirm important account operations. It adds a transaction layer after sign-in so possession of the login password alone is not enough for many actions.
Because it is reusable, it must be protected more carefully than a short-lived verification code.
2. Why KuCoin separates login and transaction authorization
Login answers whether someone may enter the account. The Trading Password confirms sensitive activity inside it. Separate credentials can slow an attacker who stole only one secret.
The protection fails if both values are stored together or reused elsewhere.
3. Credential comparison
| Credential | Purpose | Behavior |
|---|---|---|
| Login password | Account sign-in | User-created text password |
| Trading Password | Sensitive transactions | Reusable six-digit number |
| Google 2FA | Time-based verification | Changing one-time code |
| Email/SMS code | Channel verification | Short-lived code sent on request |
| Passkey | Device-bound authentication | Cryptographic approval |
4. Trading Password versus login password
The login password can contain a complex mix of characters; the Trading Password is six digits. Entering one where the other is expected produces an error and repeated guesses can create additional risk controls.
5. Trading Password versus Google 2FA
A Google Authenticator code changes with time. The Trading Password stays the same until changed or reset. Never replace a requested Trading Password with the current authenticator code.
6. Trading Password versus passkey
A passkey can authenticate setup or account access on a trusted device, while the Trading Password remains an operation-specific secret. Enabling a passkey does not mean the six-digit credential should be forgotten.
7. Where KuCoin requires it
Current KuCoin guidance identifies spot, margin and futures transactions, withdrawals and API-related actions. P2P selling and Red Packets can also depend on this security layer or be affected by its reset.
The exact prompt varies by product and verification-frequency setting.
8. Spot trading
The password can authorize order activity after the session is opened. An order can still fail afterward because assets are in Funding rather than Trading, are reserved, or do not meet size rules.
9. Margin and futures
Authorization does not confirm that leverage, direction or margin mode is safe. Read the order preview independently before entering the credential.
10. Withdrawals
A withdrawal may require the Trading Password plus other verification. A correct password cannot override a 24-hour lock, network suspension, unavailable balance or risk review.
Read each field separately before confirming. The withdrawal address and network determine the blockchain destination; the Trading Password merely authorizes the request. It cannot correct a wrong address, missing MEMO or incompatible network.
11. API actions
Creating or changing API access can require sensitive verification. The API secret and Trading Password are separate; neither should be placed into an untrusted bot or shared with an integration’s support agent.
12. Initial setup workflow
- Open KuCoin from a trusted bookmark.
- Go to Account Security.
- Select Configure beside Trading Password.
- Complete the requested passkey, 2FA, email or SMS verification.
- Create and confirm a six-digit value.
- Store it securely and close the settings page.
13. Choosing a safer six-digit value
Avoid birthdays, phone fragments, repeated digits, sequences such as 123456 and values displayed in screenshots. A six-digit space is limited, so secrecy and separation matter.
14. Do not reuse a banking PIN
Reusing a card PIN links the security of two financial accounts. Choose a KuCoin-only value that is not used for a phone, password-manager PIN, wallet device or building access.
15. Safe storage
A reputable password manager can store it as a protected custom field. An offline written record can also be appropriate if physically secured and not labeled with enough information for easy misuse.
Do not keep it in plain-text email, cloud notes, screenshots or chat history.
Recovery storage should survive loss of one phone without exposing every account secret together. Keep password-manager recovery material, email recovery and the KuCoin Trading Password in appropriately separated locations. Periodically confirm that the record is readable without repeatedly entering the value into KuCoin.
16. Verification frequency
Some KuCoin interfaces allow a frequency such as every action, one hour or a longer session period. Longer intervals improve convenience but increase what an unattended unlocked session can do.
Choose the shortest interval compatible with your workflow, especially on shared or mobile devices.
17. Changing a known password
Use Change in Account Security, enter the current value, then confirm a new six-digit value. The new credential becomes effective immediately under current guidance.
Schedule the change when you do not need an urgent withdrawal.
18. Change versus reset
| Path | Use when | Main verification |
|---|---|---|
| Change | Current value is known | Old password and security checks |
| Reset | Value is forgotten | Identity and account-control review |
19. The 24-hour withdrawal lock
KuCoin normally suspends withdrawals for 24 hours after a Trading Password change or reset. The purpose is to prevent an attacker from replacing security credentials and immediately removing assets.
The countdown is a protective delay, not evidence that funds were lost.
20. Other functions affected
Official Trading Password guidance also mentions P2P selling and Red Packets after a change. Read the notice shown in your own account before depending on any outflow.
Incoming deposits can behave differently from outgoing activity, but depositing more crypto does not shorten the protection period. Avoid adding funds solely to “test” whether the account has returned to normal.
21. Other security changes that trigger restrictions
KuCoin lists deletion of a passkey; change, unlink or reset of Google 2FA; phone or email changes; account unfreezing; and certain login-password resets among events that can suspend withdrawals for 24 hours.
22. Check the remaining countdown
The withdrawal page may show the time remaining. Take the displayed unlock time and timezone as the operational reference instead of repeatedly attempting withdrawals.
23. Planning before a security change
- Finish legitimate urgent withdrawals first.
- Close no position merely to bypass a future lock.
- Confirm access to email, 2FA and identity documents.
- Notify nobody of the new secret.
- Allow an additional buffer after the displayed time.
24. Forgot Trading Password workflow
Use Forgot password or Reset Authentication through the authenticated Security Settings or official Help Center. Select Trading Password and complete the requested verification.
Do not use a reset link delivered by an unsolicited message.
25. Identity Verification during recovery
KuCoin may request identity documents, photos or other account-control evidence. Upload only through the official workflow and follow framing and quality instructions closely.
26. Manual review time
Current KuCoin guidance estimates approximately one to three business days for a Trading Password reset appeal. This is separate from the 24-hour withdrawal restriction after the reset completes.
Do not promise funds based on the shortest estimate.
Business-day review time and the automatic lock should be planned consecutively. For example, approval after two business days can still be followed by the security countdown. Weekends, requests for clearer documents or account-specific investigation can make the total elapsed time longer.
27. Why a reset request can be rejected
Unreadable documents, inconsistent identity information, wrong requested credential or incomplete instructions can cause rejection. Read the notification email inside a verified context before resubmitting.
28. Lost Trading Password and 2FA access
If both are unavailable, use KuCoin’s official ticket or Reset Authentication process. Expect stronger identity review. Do not create a second identity or pay a third party to “unlock” the account.
29. Password appears correct but fails
Confirm that the prompt asks for Trading Password, that Num Lock and keyboard input are correct, and that you are in the intended KuCoin regional product. Stop repeated guesses and use recovery if uncertain.
30. Withdrawal remains blocked after 24 hours
Check the exact countdown, later security changes, account notices, withdrawal network and available balance. A second security change can create a new restriction period.
If no explanation appears, submit an official ticket with non-sensitive evidence.
Useful evidence includes the time of the last security change, the displayed message, coin, network and whether the balance is in Funding. Do not include the Trading Password, full identity document or complete API secret in an ordinary support message unless the authenticated workflow explicitly requests the relevant document.
31. “User Forbidden” is different
KuCoin’s withdrawal guide distinguishes a timed suspension from a User Forbidden notice. The latter requires official support to identify the account-specific cause and is not guaranteed to clear at the end of 24 hours.
32. Available balance after the lock
Once withdrawals resume, assets still need to be in the appropriate Funding Account and available. Open spot, margin, futures or lending obligations can prevent movement.
A correct Trading Password authorizes an action; it does not create transferable balance.
33. Funding and Trading Account confusion
A deposit may be held in Funding while spot orders use Trading. Internal transfer can resolve location, but it does not bypass a security restriction.
See the dedicated account-types guide for the full map.
34. Fake support warning
KuCoin states that support will never ask for the Trading Password through communication channels. Anyone requesting it by Telegram, phone, email or screen-sharing software should be treated as hostile.
A common impersonation pattern claims that a withdrawal is “stuck” and asks the user to reveal the six digits, install remote-access software or transfer a verification amount. None of these steps proves account ownership. Stop the conversation and open the official Help Center independently.
35. Anti-phishing code and domain checks
Enable an anti-phishing phrase so authentic KuCoin communications can be easier to distinguish. Bookmark the official domain and inspect the address before entering any credential.
A correct logo and page design are not proof of authenticity.
36. Official contact verification
Use KuCoin’s official verification tools and Help Center for domains or contacts. Search results and social profiles can contain impersonators. KuCoin’s security notice warns that fake support phone numbers are used for theft.
37. Emergency workflow after suspected exposure
- Stop entering credentials on the suspected page.
- Open KuCoin from a clean device and trusted bookmark.
- Freeze the account if unauthorized access is plausible.
- Secure the connected email and device.
- Change compromised credentials through official settings.
- Review sessions, API keys, orders and withdrawals.
- Submit an official support ticket.
Also inspect the email account for forwarding rules, unfamiliar recovery methods and active sessions. An attacker with persistent email access may intercept confirmations even after the KuCoin credential changes. Preserve suspicious URLs and message headers for the support case without reopening malicious links.
38. Do not “test” exposure with a withdrawal
If a phishing page received the Trading Password, assume compromise. A small test withdrawal does not prove safety and may alert an attacker to available assets.
39. Troubleshooting map
| Symptom | Likely cause | First safe action |
|---|---|---|
| 2FA code rejected in trade prompt | Prompt needs Trading Password | Read the field label |
| Withdrawal locked with countdown | Recent security change | Wait for displayed expiry |
| User Forbidden | Account-specific restriction | Contact official support |
| Reset pending | Manual identity review | Monitor verified ticket/email |
| Password works but funds unavailable | Account location or reservation | Check Funding balance and orders |

42. Frequently asked questions
Is the KuCoin Trading Password the Google 2FA code?
No. It is a separate reusable six-digit password.
Does changing it block trading for 24 hours?
The new password takes effect immediately. KuCoin specifically documents temporary restrictions on withdrawals and certain outflows; check the current account notice.
Can support tell me my old password?
No legitimate support agent should request or disclose it. Use the official reset process.
How long does reset review take?
Current guidance estimates about one to three business days, but individual review can vary.
Why is withdrawal still unavailable?
The countdown, another security change, User Forbidden status, network state, account location or reserved balance can be responsible.
