Logging into KuCoin is straightforward:
- Go to the official KuCoin website or open the mobile app.

Why You Can’t Log In to KuCoin – Causes & Fixes
Even with proper setup, several issues can block access to your KuCoin account. Below are the most frequent causes and how to resolve them.
1. Incorrect Login Information
Typing errors in your email, phone number, or password are the most common login barriers. Double-check:
- Caps Lock status (passwords are case-sensitive).
- Use of full-width vs. half-width characters (especially on non-English keyboards).
- Whether you're using the correct login method (email vs. phone).
Ensure you're entering details exactly as registered.
2. Forgotten Password
If you’ve forgotten your password:
- Click “Forgot your password?” on the login screen.
- Request a reset link via email or SMS.
- Follow the instructions to create a new password.
⚠️ Important: Entering an incorrect password five times will lock your account for two hours as a security measure. Wait or contact support if urgent.
3. Two-Step Verification Code Error
Using Google Authenticator? The 6-digit code refreshes every 30 seconds. Make sure you’re entering the current code—not one from a previous cycle.
Entering the wrong code five times also triggers a temporary lockout. To avoid this:
- Sync your device’s time with internet time servers.
- Ensure your authenticator app is functioning correctly.

4. Unable to Access Your 2FA Code
Lost your phone or uninstalled the authenticator app? Don’t panic—you can recover access:
- On the login page, click “Can’t use Google Authenticator?”
- Choose “Send Code” to receive a recovery code via email.
- Use that code to log in and reconfigure 2FA.
For full reset requests, KuCoin may require identity verification through documents like a passport, driver’s license, or residence card.
5. Account Suspension or Freeze
KuCoin may freeze accounts due to:
- Suspicious login attempts
- Unusual transaction patterns
- Violations of terms of service
- Regulatory compliance checks
If you suspect your account is frozen:
- Check your registered email for notifications.
- Contact KuCoin support directly with identification proof.
Resolution times vary but typically involve verification and explanation of activity.
6. Network Connectivity Issues
Poor internet connection can prevent access to the KuCoin site or app. To troubleshoot:
- Restart your router or switch networks (e.g., from Wi-Fi to mobile data).
- Clear browser cache or try a different browser/device.
- Disable any ad blockers or firewalls temporarily.
Ensure no malware or unauthorized devices are accessing your network.
7. Server Maintenance or Outage
Occasionally, KuCoin performs scheduled maintenance or experiences unexpected downtime. During these periods:
- The site may be slow or inaccessible.
- Login attempts may fail without error explanation.
Check KuCoin’s official social media channels or status page for updates. Most outages are resolved within hours.
