Overview
This guide explains how to use KuCoin’s self-service login features: standard login, password reset, 2-factor authentication (2FA) recovery, and account lock/unlock procedures. It focuses on steps you can take right now without contacting support, when those options are available — plus sensible security tips so you don’t accidentally compromise your account.
Quick Login Steps
- Open the official KuCoin site or app — confirm the URL is correct and you’re using the official app store download.
- Choose "Sign In" and enter your email or mobile number and password.
- Complete 2FA if enabled — enter the code from your authenticator app or SMS code.
- Optional: Device verification — you may need to complete device verification via email link or SMS code.
Self-Service Password Reset
If you forgot your password, use the password reset flow. Typical steps:
- Click Forgot password? on the sign-in screen.
- Enter the email or phone number registered with the account.
- Open the verification message (email or SMS) and follow the secure link to set a new password.
- Choose a strong, unique password and enable 2FA if you haven’t yet.
Important: password reset links expire. If a link doesn't work, request a new one and avoid reusing old passwords.
2FA (Authenticator) Lost? Use Recovery Options
Losing access to your authenticator app is common — there are safe recovery options:
- Backup codes: If you saved backup codes during 2FA setup, use them to regain access.
- SMS/Email fallback: Some accounts allow SMS or email as fallback verification for sign-in or 2FA reset.
- Self-service recovery: KuCoin offers a recovery process which may ask for identity verification and evidence of account ownership (trade history, deposit records). Follow the on-screen prompts carefully.
Always store backup codes in a secure password manager or an encrypted file — not as plain text on your device.
Troubleshooting Common Problems
Can’t receive SMS codes
- Check mobile network and country code.
- Disable SMS blockers or apps that filter messages.
- Try the email verification option if available.
Verification email not arriving
- Search spam/junk/promotions folders.
- Ensure your email provider is not blocking messages from KuCoin.
- Request a new code — don’t click expired or suspicious links.
Account locked after multiple failed attempts
Wait the cooldown period shown on screen. If the lock persists beyond the stated wait time, use the self-service recovery options or contact official support with identity evidence.
Security Best Practices
- Use a strong, unique password and a reputable password manager.
- Enable 2FA with an authenticator app (e.g., Authy, Google Authenticator) instead of SMS where possible.
- Keep your recovery codes in an encrypted backup.
- Enable device verification and whitelist trusted devices when supported.
- Be vigilant about phishing: check sender addresses and never enter credentials via unknown links.
Example strong password pattern:
Adjective+Noun+Symbol+4digits → "CrimsonTiger!4729"
When to Use Support
Self-service handles most routine issues. Contact official support only if:
- You cannot access the registered email or phone.
- Your account shows unauthorized transactions.
- 2FA recovery options are exhausted and you lack backup codes.
When contacting support, provide clear evidence: screenshots, transaction IDs, deposit timestamps, and original device info — never share your password or full private keys in messages.
FAQ
How long does a password reset take?
Typically minutes — but it depends on email/SMS delivery. If messages are delayed, check spam and request a new code after the expiry window.
Can I use Google Authenticator on multiple devices?
Authenticator apps generate codes from a shared secret. You can set up multiple devices by scanning the same QR code during initial 2FA setup — but do this only from secure, trusted devices.
Is SMS 2FA safe?
SMS 2FA is better than nothing but is vulnerable to SIM-swap attacks. Prefer authenticator apps or hardware keys for stronger protection.
Checklist — Before You Start
- Access to the registered email or phone.
