How to Enable Two-Factor Authentication (2FA) for Your CEX.IO Account

Two-factor authentication (2FA) adds a critical security layer to protect your account and funds. When enabled, 2FA requires a one-time password (OTP) during login, ensuring only authorized users can access your account.

Why 2FA Matters

• Enhanced Security: Combats hacking, phishing, and unauthorized access.
• Multi-Factor Protection: Combines knowledge (password), possession (OTP), or biometrics.
• Mandatory for Withdrawals: CEX.IO requires 2FA for withdrawal transactions.

Methods to Enable 2FA

CEX.IO supports two 2FA methods:

1. Authenticator Apps (e.g., Google Authenticator)
2. SMS Verification
   👉 Boost your security with both methods

Enabling 2FA via the CEX.IO Mobile App

1. Open the CEX.IO App: Log in and tap the Profile icon.
2. Navigate to Security > Two-Factor Authentication.

Yes! Enabling both methods provides backup options if one fails.

Use the saved secret code to recover access.

3. Is 2FA mandatory for all transactions?
Only withdrawals require 2FA; logins and deposits do not.

Authenticator apps are safer as SMS can be intercepted.

Pro Tips
