The best way that I know to "clean slate" a profile is; 1) determine which login methods you currently have 2) determine which ones you wish to keep for your new profile 3) Create a "dummy" or disposable login method (preferrably of a type that you don't have linked to your current profile) 4) Link that "dummy" login method to the current account that you intend to walk away from. 5) Unlink the logins/accounts that you plan on keeping/using with your new profile. 6) Create a new Bungie.Net account with those now unlinked accounts 7) Make sure that the account you are "walking away from" only has your new and disposable "dummy" account linked. 8) Use your new Bungie.Net account (with the proper linked methods that you want) and ignore the old Bungie.Net account & the disposable login that you created for this process.
