Overview
CEX.io is a cryptocurrency exchange used by traders and investors around the world. This guide explains the standard login process, how to set up and use two-factor authentication (2FA), steps to recover access if you’re locked out, common troubleshooting tips, and recommended security best practices to protect your account.
How to sign in (step-by-step)
- Open the CEX.io website or the official mobile app.
- Click Sign In (or tap the profile icon on mobile).
- Enter the email address associated with your account and your password.
- If prompted, complete two-factor authentication (2FA) using your chosen method (authenticator app or SMS when available).
- After successful authentication you’ll land on your dashboard — confirm recent activity and balances before trading.
Two-factor authentication (2FA)
2FA significantly reduces the risk of unauthorized access. Prefer an authenticator app (Google Authenticator, Authy, etc.) over SMS where possible.
- Enable 2FA from Security settings after you log in.
- Save backup/recovery codes in a secure place (offline password manager or physical safe).
- If you change phones, transfer your authenticator accounts or use the backup codes to re-enable 2FA.
Troubleshooting common login issues
If you cannot sign in, try these steps first:
- Confirm you’re entering the correct email and password; check for extra spaces or Caps Lock.
- Use the Forgot password flow to reset a lost password — follow the email instructions carefully.
- If 2FA codes are failing, check that your device time is set to automatic (authenticator apps require correct device time).
- Clear browser cache/cookies or try an incognito/private window.
- Disable browser extensions temporarily that might interfere with the site.
Account recovery
If you lose access to your email or 2FA, use the platform’s account recovery procedures. Expect identity verification steps (photo ID, selfie, and additional documentation). Keep copies of identity documents ready to speed up recovery.
Security best practices
- Use a long, unique password and a reputable password manager.
- Enable 2FA with an authenticator app and store backup codes offline.
- Keep software and OS up to date; avoid public Wi-Fi for account access.
- Monitor account activity and enable notifications for logins and withdrawals.
- Beware of phishing: check the URL carefully and never share passwords or 2FA codes with anyone.
FAQ
- Q: I didn’t receive a password reset email — what now?
- A: Check spam folders, ensure the email is the one registered with CEX.io, and confirm your mail server isn’t blocking automated messages.
- Q: My authenticator app shows an invalid code.
- A: Sync your device time to automatic and try again. If still failing, use saved recovery codes or the platform’s recovery flow.
- Q: Is SMS 2FA secure?
- A: SMS is better than nothing but vulnerable to SIM swap attacks — authenticator apps or hardware keys are safer.
