Starting from September 15, Xbox now requires users to sign in at least once every 5 years to keep their Gamertag associated to their Microsoft account. As seen in Microsoft’s Services Agreement, the most notable change will require users to sign in once in a 5 year period so as to maintain this unique username on Microsoft’s Xbox Live.
In the Microsoft Account or Skype Account section, we’ve added a requirement that you must sign into the Xbox Services at least once in a 5-year period to keep the Xbox gamertag associated with your Microsoft account. We’ve also added that if your account is compromised, we may be required to disable access to certain content.
As of now, the obligatory sign in applies only to a user’s Microsoft or Skype account. Users that fail to do this might lose access to the gamertag associated with their Microsoft account, and that gamertag may become available for use by other XBL users.
A Gamertag is the universal name for a player’s username on Microsoft’s Xbox Live. A Gamertag used online must be unique and can be up to fifteen characters in length, including numbers, letters, and spaces. Gamertags can be changed using an Xbox One or Xbox 360 console (first time is free, then for a price of $10), the Xbox 360 supports eight Xbox Live-enabled profiles per memory unit and thirty-two profiles on the hard drive.
A player’s Gamertag account status can be checked using a variety of online tools, which is useful especially when looking for a new Gamertag, or confirming that a Gamertag exists. Using a valid Gamertag, any player can be located and messaged from within Live. There are also several websites which allow users of Gamertags to upload photos and information about themselves..
