When you enable 2-Step Verification on your smartphone or tablet, the generated codes remain tied to that device. This is to ensure the integrity of this security feature.
This means that there is no direct way to transfer the activated instance of 2-Step Verification.
To set up 2-Step Verification again, please disable the current instance using one of your verification or recovery codes first.
You can then enable it again on your new mobile device or email account.
If you are having trouble generating a valid verification code, or have lost access to your recovery codes, please do not hesitate to contact us for help with disabling 2-Step Verification.
