Overview
CEX.io is a cryptocurrency exchange offering trading, staking, and fiat on/off ramps. This page explains how to sign in to your CEX.io account, what to do if you can’t log in, and how to secure access using two-factor authentication (2FA). Follow the steps below to avoid common pitfalls and keep your crypto safe.
How to Sign In (Step-by-step)
- Open your browser and go to the official CEX.io website (ensure the URL is correct and secure: starts with
https://).
- Click Sign In or Log In at the top-right corner.
- Enter your registered email address and password. Make sure there are no accidental spaces before or after your email.
- If you enabled Two-Factor Authentication (2FA), provide the code from your authenticator app (Google Authenticator, Authy, etc.) when prompted.
- After successful verification you’ll land on your CEX.io dashboard.
Tip: Use a password manager to autofill credentials securely and reduce mistyping.
Forgot Password & Account Recovery
If you forget your password:
- Click Forgot password? on the login page.
- Enter your registered email — CEX.io will send a password reset link. Follow the link and set a strong, unique password.
- If you don’t receive the email, check spam/junk folders and any email filters. Ensure your mailbox isn’t full.
- If you no longer have access to that email, contact CEX.io Support and be ready to verify identity (KYC documents, previous transaction details, etc.).
Two-Factor Authentication (2FA)
2FA adds an extra security layer. After entering your password, you’ll need a code from an authenticator app or an SMS code (if enabled).
- To enable 2FA: go to Security or Account Settings and follow the prompts to link your authenticator app.
- Save backup/recovery codes in a secure vault. These codes let you regain access if you lose your device.
- If you lose your 2FA device, use the recovery codes or contact support — expect identity verification before 2FA reset.
Common Login Issues & Troubleshooting
- Incorrect password: Reset it using the "Forgot password" flow.
- Authenticator codes not accepted: Make sure device time is correct (synchronized) and the app is set to the right account.
- Login email not recognized: Confirm the address you registered with. If you used a social login (Google, Apple), use that option instead.
- Blocked or limited access: CEX.io may temporarily block logins after suspicious activity; check your email for security alerts and follow instructions.
- Browser issues: Clear cache/cookies or try an incognito window. Disable ad blockers or browser extensions that may interfere.
Best Practices for Secure Login
- Always use a unique, strong password — consider passphrases of 12+ characters.
- Enable 2FA via an authenticator app rather than SMS when possible.
- Keep recovery codes in a safe place (offline or in an encrypted vault).
- Beware of phishing: never click email links unless you confirm the sender and URL. Type the CEX.io address directly into your browser.
- Use hardware wallets for large holdings and enable withdrawal whitelists where available.
