> However, because we’re a regulated financial institution, we’re required by law to keep some core records about your account and activity (including certain identifiers tied to those records) even after a deletion request is processed.

But, for example, my understanding is that something like "password" is used for authentication/validation and NOT for identification of an account. It is only personal information because of its relationship with the account, and is not PII in itself. So this is why I want more specific information about which laws/regulations prevent you from deleting what information. My understanding is that information like this is not required to be retained by FINRA or GLBA.

How do I do this? I have not seen any information about how to permanently close an account.

Thanks for your help,
