If you need to change the phone number at which you receive 2FA codes or switch your 2FA method to Authenticator app, there are two ways to do that:

  • Disconnect your previous phone number on the Security page.

  • Request 2FA disable for your account.

I have access to my previous phone number/device

If you have access to the phone number that’s currently registered for receiving 2FA codes, you can change it in the Profile menu, under the Security tab. The same way users can add 2FA method using the Authenticator app method.

How to change the phone number for 2FA codes

  • Click Disable next to the Text Message option for 2FA

  • Read the security warning and click Confirm to proceed.

  • Authorize 2FA disable with the code sent to your phone number

Click Confirm to continue.

To re-enable 2FA with your new phone number:

  • Click Enable next to Text Message option for 2FA

  • Enter your new phone number

  • Enter the 2FA code sent to your new phone number

That’s it! Now you’ll receive 2FA codes delivered to your new phone number.

Lost access to previous phone number/device

If you need to change the phone number that delivers 2FA codes, submit 2FA disable request. Log in to your CEX.IO account using your email address and password and click Lost authentication device.

After that, provide the necessary information and photos. Once we receive and verify your request, 2FA will be disabled on your account so you can enable it again with the new phone number.
