Biometric Login (If Enabled):

  • After initial login, you can enable fingerprint or facial recognition

  • Future logins can use biometric authentication for faster access

  • This provides both convenience and security 

Understanding Multi-Factor Authentication (MFA) on KuCoin

KuCoin uses Multi-Factor Authentication to add extra protection beyond your password. When MFA is enabled, you perform a second type of verification after entering your username and password .

MFA methods supported by KuCoin: 

  • Email verification codes – Sent to your registered email

  • SMS verification codes – Sent to your registered phone number

  • Google Authenticator (Google 2FA) – 6-digit codes from an authenticator app

Additional security measures:

  • If the system detects significant anomalies in device or IP address, email verification links are sent as extra reinforcement 

  • These measures help prevent phishing attacks and telecom fraud 

Part 4: Security Settings on KuCoin

KuCoin offers multiple security layers to protect your account.

1. Login Password Requirements

To effectively protect user accounts, KuCoin enforces strong password requirements. Your password must include :

  • An uppercase letter

  • A lowercase letter

  • A number

  • Length of 10 to 32 characters

2. Multi-Factor Authentication (MFA)

MFA is a simple but effective measure that adds an extra layer of protection. When enabled, you must provide a second verification method in addition to your username and password .

3. Trading Password

The Trading Password is a six-digit code set by users to verify all transactions on KuCoin, including :

  • Spot trading

  • Withdrawals

  • API-related actions

4. Biometric Authentication (Mobile App)

The KuCoin app offers biometric authentication options, such as fingerprint and facial recognition, for quick and secure identity verification .

Part 5: How to Set Up Google Authenticator 2FA

Google Authenticator is the most secure 2FA method supported by KuCoin.

  8. Google 2FA is now enabled for your account

What If You Lose Access to Google 2FA?

If you lose your phone or cannot access your authenticator app:

  • Use your backup key to restore access

  • If you no longer have the backup key, use the "Security verification not available" option during login

Part 7: Troubleshooting Common KuCoin Login Issues

Even reliable platforms sometimes present login challenges. Here is how to resolve the most common issues.

Issue 1: Incorrect Verification Information – Account Lockout

Problem: Entering incorrect verification information more than 5 times will result in a 2-hour account lockout .

Solution:

  • Wait for the 2-hour lockout period to expire

  • Do not continue attempting during lockout—it may extend the restriction

  • Use this time to double-check your credentials and verification codes

Issue 2: Cannot Receive Email or SMS Verification Code

If you are not receiving verification codes :

Possible causes and solutions:

  • Check spam/junk folder – Search for emails from KuCoin

  • Verify correct contact information – Ensure you're checking the registered email/phone

  • Wait a few minutes – Delivery can sometimes be delayed

  • Request a new code – Use the "Resend" option

  • Check phone signal – SMS requires network connectivity

  • Add KuCoin to contacts – Prevents spam filtering

Issue 3: Google 2FA Code Not Working

If your authenticator app code is being rejected:

Solutions:

  • Time sync issue – Ensure your phone's time is set to automatic (network time)

  • Wait for new code – Google Authenticator codes refresh every 30 seconds

  • Try restarting – Close and reopen the authenticator app

  • Use backup codes – If you saved them during setup

For persistent issues, refer to KuCoin's guide on "How to Unbind or Change Google 2FA" .

Issue 4: Unable to Log In with Phone

If you are having issues logging in with your phone number :

Solutions:

  • Verify you are using the correct registered phone number

  • Check that the country code is correct

  • If you have changed your phone number, refer to "How to Change Your Phone Number" guide

  • Consider logging in with email as an alternative

Issue 5: Forgot Password

If you cannot remember your password :

  1. Click "Forgot password?" on the login page

  2. Enter your registered email or phone number

  3. Check your email/SMS for reset instructions

  4. Create a new strong password (meeting the 10-32 character requirement with uppercase, lowercase, and number)

  5. Log in with your new credentials

Issue 6: Platform Login Unavailability (Regional Notices)

Important regional notice (KuCoin Thailand):

On April 22, 2026, KuCoin Thailand announced a temporary system closure. Users cannot log in to their accounts starting April 22, 2026, at 13:00 (UTC+7) until further notice .

During this period:

  • Customers cannot log in to their accounts

  • Customers cannot view asset balances or transaction history via the system

  • Customers cannot withdraw assets via the system

What you can do:

  • Request transaction details by contacting support at happy@kucoin.th

  • Submit a request for manual withdrawal via email

  • Refer to the End-of-Day Asset Balance Report sent to registered emails 

Note: This notice applies specifically to KuCoin Thailand. Other regions should check their local KuCoin platform status.

Issue 7: Account Frozen or Restricted

KuCoin may temporarily freeze or restrict accounts for security and compliance reasons, including :

  • Suspicious login activity or unusual transactions

  • Incomplete identity verification (KYC)

  • Recent security changes (password, phone number, 2FA changes)

  • Compliance checks for regulatory reasons

What to do if your account is frozen:

  1. Check your email for notifications from KuCoin explaining the reason

  2. Complete any pending verification steps

  3. Reset security settings if needed

  4. Contact KuCoin Support for assistance 

Important: Your funds are usually safe during restriction periods, and most issues are temporary .

Part 8: KYC Verification – When and Why

While KuCoin does not require KYC for basic trading, completing identity verification unlocks features and higher limits.

Why Complete KYC?

  • Higher withdrawal limits

  • Access to additional features

  • Faster customer support resolution

  • Required for certain transactions

Common KYC Rejection Reasons

According to KuCoin support resources, KYC verification may be rejected for :

  • Unclear or blurry documents – Low quality, cropped, or shadowed images

  • Details do not match – Name, date of birth must exactly match your ID

  • Expired ID – Using an expired passport or ID card

  • Face verification issue – Selfie does not match ID or poor lighting

  • Too many attempts – Multiple failures can temporarily block the process

How to Fix KYC Issues

  1. Upload clear documents using a high-quality camera and good lighting

  2. Ensure all information exactly matches your ID

  3. Use valid, non-expired government ID

  4. Retry face verification in a well-lit place

  5. Wait for a response before submitting again to avoid temporary blocks 

Part 9: Security Best Practices for KuCoin Users

Protecting your KuCoin account requires proactive security habits.

1. Enable Google Authenticator 2FA

App-based 2FA is more secure than SMS. Set up Google Authenticator immediately after creating your account .

2. Set a Trading Password

Create a six-digit trading password for all transactions, including withdrawals and API actions .

3. Save Backup Codes and Recovery Keys

Store your Google Authenticator backup key offline (written down in a secure location, not just on your phone).

4. Enable Biometric Login on Mobile

Use fingerprint or facial recognition on the KuCoin app for faster, more secure access .

5. Never Share Credentials

KuCoin will never ask for your password or 2FA codes. Be wary of phishing attempts.

6. Monitor Active Sessions

Regularly check your account activity and terminate any unrecognized sessions.

7. Complete KYC Verification

Even if not required, completing KYC adds legitimacy to your account and unlocks higher limits .

8. Avoid Multiple Failed Attempts

Entering incorrect verification information more than 5 times results in a 2-hour account lockout. Be careful during login .
