Intuit, tax and quickbooks. In addition to quickbooks online not being great, Just an example: I own the gmail for my name, somebody used it by mistake on turbo tax so I get their emails. I called their support and explained it to them but I have to give personal info on the account but I don’t own the account. It was like that for years until recently they fix it, although I already had created a filter for it. Similar happened with mint.
