Two-factor authentication, or 2FA, is an extra layer of security that helps keep your account and funds protected. When 2fa is enabled, you should log in to the account using a one-time password that is only valid for 30 seconds. So, no one except you can access your account and funds. We at CEX.IO are working to ensure that all accounts are protected from any possible attacks, and by default we suggest adding 2FA.
You can enable 2FA on your CEX.IO account in two methods: by using your phone number or a special Google Authenticator app. We recommend the Google app method, as it doesn't require a good network connection. Besides, the Google app is more secure for receiving 2FA codes compared to the SMS/phone calls since there are SIM swaps and other phone number-based hacks.
To enable 2FA on your CEX.IO account:
Log in to your account
Go to your Profile and select the Security tab
Click Enable 2FA
Then you should choose the method you want to receive your 2FA codes.
This type of 2FA provides a code via SMS messages or phone calls. You should have a valid and actual phone number to activate this option.
To enable 2FA via the SMS or call option:
Enter your phone number
Click on either SMS or Call Request
Enter the 2FA code you receive via text message or phone call
Smartphone app method
To enable 2FA using the smartphone app, install the Google Authenticator app on your smartphone. Then, go to your CEX.IO account and choose this method on the Security tab of the Profile menu.
Download and save your 2FA backup key. With this key, you can change the device for receiving 2FA codes or restore access to your account if you lose your phone.
Scan the QR code with the Google Authenticator app to link your CEX.IO account.
Enter the 6-digit code generated by Google Authenticator and enable 2FA.
