Xbox 360 (passord)

You would need to contact xbox support by going to support.xbox.com/contact-us and they would be able to give you a series of button pushes to put in on your controller on the system info screen that will reset your console including the family passcode

Have you double checked the email is spelt correctly. and that there no errors in the passord on trying to sign in ?

Hi there,

in order to reset a family passcode you will need to contact Xbox Support, They will need the serial ID of the console and will do something on their end, after which they will guide you through the steps to reset it on your end.

To contact Xbox Support (Phone or Microsoft Support Chat) via http://support.xbox.com/contact-us

i need help to reset my japan account passord and rewrite backup email address , i had already follow the ms homepage step ,they dont give me code to reset account ,[Mod Removed - Please don't post personal information]

If you have not yet purchased your new slim, I would change the passord ASAP here at Xbox.com, and then also at the Xbox.com site, you might want to go to "My Account," and then
Xbox Profile Protection (in case the link does not work, it can be found under the "Settings and Preferences" column). From there, you will see a list of your consoles that do not
require a password for sign-in. If your old console is listed there, you should click "require profile download" for that console. Then if access to your profile is attempted on the old console, it should prompt them for the WLID and password.
