Hi there, Thank you for reaching out. To be able to remove your Twitch account from your Bungie profile, you must be able to authenticate it. If you cannot, then unfortunately the account in question will remain linked. Further, as Bungie entrusts players with the security and management regarding linking their accounts, we do not unlink any accounts on players' behalf. Thus, your only recourse is to reach out to Twitch's support team in the hope of recovering the account in question, then unlinking it following recovery.
