Hi, Two-part security appears to be using an out-of-date (ie no longer owned ) mobile phone number to send a security check when logging in from a new device although the correct new mobile number has been set in my bt account. The only way the problem was solved (by a bit help assistant ) is to suggest turning off two-part security!!! What a ludicrous situation There appears to be no way to update the mobile number on the Security process itself! And Security is sending a message to an insecure location.
