Sorry for the double post, this is not an issue, if you can get locked out of WoW because of a factory reset/reflash it made wrong.

Every phone has a unique identifier called and IMEI, this is unique to each phone, app devs can access this IMEI number and for an authenticator app it can be used in the algorithm to work out the OTP.

This will protect users against accout lockouts because of a factory reset or reflash, the only problem will be when you get a new phone, which needs a workaround, its not a problem you will see every day, seeing as (atleast in UK) people are on 2yr contracts so they have to keep their phone for at least 2 years.


The work around could be using a code based on your phone's IMEI, which you can copy over to a new one if needed and it overwrites the default IMEI based algorithm.
