19. The MSISDN is not good but sometimes it is requested, at least to be used as a partial user id because the real email (and other customer details) may not be shared due to contract reasons. I understood that in IPification the MobileID would be changed as although MSISDN is the same, the IMEI would be different and hence trigger a user verification to assign a new MobileID, correct? If yes, in this case, we will receive a request to start a new OAUTH authentication, correct?
Exactly like that. Whatever is changed, IMSI (sim change) or IMEI (device change) the MobileID will be different and you won’t be able to resolve user based on MobileID. So, you need to handle this scenario like account recovery, so the user must confirm his identity by some other channel (email, or username/password). After confirmation, you will just assign a new MobileID to that account.
