Hello Xbox Support,
Firstly, I apologise if this post is listed incorrectly on this forum, I was undecided on whether to use forum 2 (Connecting To Xbox LIVE) or Forum 3 (Managing My Xbox Live Account).
I am currently having a problem with an "Add Security" log-in prompt when connecting or attempting to connect to the Xbox LIVE service. I have been having this issue persistently for approximately one week now and I believe I have exhausted all possible solutions available to me, unfortunately to no avail.
Before I begin to detail the problem; for your information I do have two step verification enabled on my Microsoft Account, I also have two working and verified email addresses listed as security proofs plus a working and verified telephone number. In addition I have a working and verified application password for my Xbox 360 console as "some apps... or devices can't prompt you to enter a security proof when you try to sign in" - http://support.xbox.com/en-GB/billing-and-subscriptions/account-security/no-prompt-security-proof
Please note that all of the proofs listed above are validated and are listed accurately within the security section(s) of my Microsoft Account.
Now, as mentioned previously, every time I connect to the Xbox LIVE service I am being presented with an "Add Security" log-in prompt that asks me to enter my email address and password/application password in order for me to check and confirm the security proofs listed under my Microsoft/Xbox LIVE Account. I have absolutely no problem doing this. If my log-in is successful the following screens will list my security proofs correctly and I am able to successfully sign-in to the service. When I sign-out, power down or restart the console I am presented with this same "Add Security" log-in prompt.
I suppose that I could live with this situation, however, many times after I input my security information in to the "Add Security" log-in prompt, the system loads/buffers over the "do you want your password to be remembered" window, shortly afterwards I am presented with error code 80151103 which suggests that there is a temporary problem with the Xbox LIVE service or that my account is blocked. If I am presented with this error message I am physically unable to connect to the Xbox LIVE service. In order to rectify this problem I have to delete my profile (only) and re-download my profile with the exact same log-in credentials, this always works and eventually I am able to sign-in successfully, only to be presented with the "Add Security" log-in prompt the next time I attempt to sign in.
I have done many things in order to stop this "Add Security" log-in prompt from appearing unnecessarily on my Xbox 360 console. I have deleted and re-downloaded my profile more times in this last week than I have in my entire 6/7 year tenure with Xbox LIVE. I have followed some possible solutions to the letter, many of which are detailed within these support forums:
- Clearing the cache 3 times in-between deleting and downloading my Xbox LIVE profile
- Logging in to my Microsoft Account and confirming/verifying my security proofs
- Disabling and Re-enabling two-step verification on my Microsoft Account
All of the above fails. I do feel as though this is harsh price to pay for in today's world having a sufficient level of security installed on my Xbox LIVE/Microsoft Account, and this for me is a real last ditch attempt and trying to get this issue resolved. Obviously I would appreciate any support in regard to this matter, but I do believe official assistance will be required in order to fix this problem.
