Two-factor authentication, or 2FA, is an extra layer of security that helps keep your account and funds secure. When 2FA is enabled, you are required to enter a one-time password to log into your account. This extra layer of security prevents anyone except you from accessing your account and funds.

2FA is a security measure that protects users from security leaks. By default, the first factor used to authenticate a person’s identity is a username and password. 2FA works like another line of defense against hackers, phishers, and bad actors by requiring another piece of information after using the right username and password. The second factor can include something you know (security questions), something you have (a temporary pin number texted to your phone), or something you are (biometric devices).

We at CEX.IO are working diligently to ensure that all accounts are protected. For this reason, we recommend all of our users implement 2FA into their CEX.IO account. Please note that 2FA is mandatory when making withdrawals with your CEX.IO account.

You can enable 2FA on your CEX.IO account by using your phone number or a special authenticator app (iOS, Android). You can choose one of the two methods to activate 2FA. But we recommend enabling both phone and authenticator methods at the same time to make your account even more secure. When both 2FA methods are enabled simultaneously, you can choose which method you would like to use to authenticate your login.

1. Open the CEX.IO mobile app. Log in to your account and tap the profile icon in the upper left.

2. Scroll down the page and select the Two-Factor Authentication option.

For Android Devices: Open the Google Play Store on your Android device > Search for "Google Authenticator" > Tap "Install" to download and install the app.

This type of 2FA provides a code via text messages. You should have a valid phone number to activate this option.

To enable 2FA via the text message option, repeat the same steps:

1. Go to the CEX.IO website, log in to your account using your email and password, and enter the 2FA code from your Google Authenticator.

2. Once logged in, click on your account profile icon and select the "Security" tab from the dropdown menu.

6. Choose your country, enter your phone number, and click Next. A verification code will be sent to your phone number via SMS.

7. Enter the code from the SMS message into the "Verification code" field and click Next.

8. The second method 2FA via the Text message is enabled on your account.

After enabling the desired methods, ensure both are working by logging out and attempting to log back in.

This process allows you to have an additional layer of security with the flexibility of using either Google Authenticator or Text Message for two-factor authentication.

However, we recommend using both text messages and the authenticator app to enhance your account's security.
