You could easily mistake Alec Harris for a spy or an escaped prisoner, given all of the tradecraft he devotes to being unfindable. Mail addressed to him goes to a UPS Store. To buy things online, he uses a YubiKey, a small piece of hardware resembling a thumb drive, to open Bitwarden, a password manager that stores his hundreds of unique, long, random passwords. Then he logs in to Privacy.com, a subscription service that lets him open virtual debit cards under as many different names as he wishes; Harris has 191 cards at this point, each specific to a single vendor but all linked to the same bank account. This isolates risk: If any vendor is breached, whatever information it has about him won’t be exploitable anywhere else.
