Hi there, Thank you for reaching out to us. If you're seeking to change your username, then be advised that players have a limited number of name changes available. As such, if you've changed your name in the past, then it may not be currently possible. For more information about changing your Bungie Name, please refer to our [url=https://help.bungie.net/hc/en-us/articles/7648312251284-Bungie-Name-Guide]Bungie Name Guide[/url]. If, however, you're referring to the credentials for your platform accounts, then please clarify if you mean to say their names won't update on your Bungie account. We'll then review.
