How can I transfer security software token to another phone?

iphone full backup and then restore to your new phone should copy all the required stuff that was missing... Also make sure clould backup is enabled per app it will save the settings etc from the auth if that doesnt work you did write down your origonal install code for the auth right?

The original install code won't do you any good since they expire after an hour. The only way I could figure to do it when I needed to wipe my phone was to just disable my current token with the emergency removal code (found on security token page of account management, you will have to answer a security question and put in this code when you do the removal) and then set up a new token as soon as you have the new phone set up. Yes this leaves your account vulnerable for 30-60min while you wipe/set up a new phone, but I figure that is a small chance to take, highly unlikely you are gonna get spammed the same exact time you are doing that.
