Troubleshooting KuCoin Login Issues — Step-by-Step Help

If you’re having trouble signing in to KuCoin — forgotten password, 2FA failure, locked account, app error, or suspected compromise — this guide walks you through safe, ordered steps to diagnose and fix the problem. Follow the steps below carefully, use only KuCoin’s verified support channels for sensitive actions, and avoid entering credentials on untrusted pages.

Important: This is an educational guide and not the official KuCoin login page. For account actions always use KuCoin’s verified site, official app, or support center links in the Resources panel.

Quick checklist — what to try first

Many login problems are simple to fix. Try these quick checks before moving to recovery steps:

  • Confirm you opened KuCoin via a bookmark or by typing kucoin.com — avoid clicking links in email or chat.
  • Check keyboard layout and caps lock; paste your password from a password manager rather than retyping it.
  • Restart the KuCoin app or browser, and reboot your device — sometimes stale sessions or temporary glitches cause sign-in failures.
  • Try an incognito/private browser window to rule out interfering extensions or cached sessions.
  • If many users are reporting issues, check KuCoin’s status page before making repeated reset attempts.

Step 1 — Use the official password-reset flow

If you forgot your password or suspect it was changed, use KuCoin’s official “Forgot password” flow. Request a reset link to the email associated with the account and follow KuCoin’s instructions. If the reset email doesn't arrive, check your spam/junk folder and ensure you used the correct email address. If a reset link expires, request a new one rather than reusing old links.

Important security tips while resetting:

  • Only click the reset link that comes from KuCoin’s official domain and email address.
  • Never provide passwords or 2FA codes to anyone who contacts you saying they’re support. KuCoin will not ask for your password via email or chat.
  • If you do not control the recovery email or can’t access it, you’ll need to use KuCoin’s verified support/recovery process.

Step 2 — Troubleshoot two-factor authentication (2FA)

Two-factor authentication (2FA) protects your account but can also block you if a code or device is lost. KuCoin supports authenticator apps and other 2FA options — check their help center for exact setup steps. If you use Google Authenticator, Authy, or a similar app, the most common 2FA problems are:

  • Time drift: TOTP codes depend on correct device time. If codes are rejected, ensure your phone’s clock is set to automatic network time.
  • Lost device: If you lost the phone with your authenticator, use any saved backup/one-time codes you stored offline. If you don’t have backups, you’ll need to follow KuCoin’s account recovery procedures.
  • SMS delays: SMS-based codes may be delayed or blocked; also note SMS is less secure and vulnerable to SIM-swap attacks.
Tip: When enabling 2FA, save the backup codes KuCoin provides and store them in a safe, offline location (paper safe or encrypted vault).

Step 3 — Account recovery & identity flows (when automated flows fail)

If password reset and 2FA recovery don’t work — for example, if you cannot access your email or lost MFA — KuCoin may require identity verification. Commonly this involves submitting ID photos, a selfie with a handwritten note, or other verifiable documents through KuCoin’s official support portal. Follow KuCoin’s ARP (Account Recovery) instructions exactly — they typically specify what documents, photo formats, and note wording are acceptable.

Practical ARP tips:

  • Take clear photos in good light showing both your face and the ID document simultaneously if requested.
  • Write the exact phrase KuCoin asks for on a piece of paper (do not improvise), and include the current date if required.
  • Only upload documents via KuCoin’s secure support portal; never email sensitive documents to unknown addresses.

Step 4 — App and browser troubleshooting

If the KuCoin app or website behaves inconsistently (frozen screen, errors, or Cloudflare/anti-bot pages), try these device-level steps:

  1. Force-quit the app and reopen it. Reboot your phone or computer.
  2. Ensure you’re running the latest app version from the official store (App Store / Google Play) or the latest browser version.
  3. Clear site cookies and cache or try an incognito/private browsing window to rule out extensions.
  4. If you see access-limiting messages (rate-limited, blocked), consult KuCoin’s status or support pages for guidance rather than repeatedly reloading.

Step 5 — Check status & platform incidents

Before escalating by opening support tickets or repeatedly resetting credentials, verify whether KuCoin is experiencing a known outage or incident. Check KuCoin’s system status page and official announcements; if there’s a platform-wide issue, you’ll likely save time by waiting for an official fix rather than repeating recovery attempts that may be impacted by the outage.

Step 6 — Be sure it’s not phishing

Phishing is incredibly common. Attackers will send fake emails or texts that appear to come from KuCoin and link to counterfeit login pages. To avoid phishing:

  • Never click login links in unsolicited messages; type kucoin.com manually or use a trusted bookmark.
  • Inspect the sender’s email address for subtle misspellings or extra words.
  • Use a password manager — it will only autofill on exact domains, so if it won’t fill, the page may be fake.
  • Report suspicious emails to KuCoin via their official support contact rather than engaging with the sender.

If you suspect your account was compromised — immediate steps

If you believe someone else has access to your account, act promptly and safely:

  1. From a known-secure device and network, change your KuCoin password and revoke any active sessions if the account remains accessible.
  2. Disable or reset any MFA methods that may be exposed and re-register stronger options (hardware security key / passkey) where supported.
  3. Open a support ticket through KuCoin’s verified support portal and report the suspected unauthorized activity — include timestamps and transaction IDs if available.
  4. Contact your bank/payment provider if funds were moved or there is risk to linked accounts, and consider fraud alerts with credit bureaus when appropriate.

Prevention & good habits to avoid future lockouts

  • Use a reputable password manager and unique passwords for every service.
  • Enable 2FA (authenticator app or hardware key) and keep offline backups of recovery codes.
  • Secure your recovery email with MFA and a unique password.
  • Bookmark KuCoin and avoid entering credentials after following links in unsolicited messages.
  • Consider registering a spare hardware key and storing it securely if you rely on hardware-based 2FA.
  • Regularly review KuCoin’s official support pages so you know official recovery procedures ahead of time.

When to contact KuCoin support

Contact KuCoin support through their verified support center when:

  • Automated password reset and 2FA recovery methods fail.
  • Your account shows unauthorized trades or withdrawals.
  • You need manual review for identity verification (ARP) or other special recovery steps.

This guide is educational and intentionally generic. For account-specific instructions (resets, ARP submissions, or suspected fraud), use KuCoin’s verified support pages and the official app — never share passwords or one-time codes with anyone claiming to be support via unsolicited messages.
