This document discusses various ways to secure digital assets and web applications using Latch, an open source tool for pairing and enforcing access controls. It provides overviews of Latch plugins for Windows, WordPress, Docker, IoT devices, and other platforms. Examples are given for configuring Latch on servers, WordPress sites, and Joomla in "paranoid mode." Later sections discuss using Latch smart contracts on blockchains to control access to decentralized applications and manage pairing/status changes directly on the blockchain. The conclusion emphasizes the need to harden and pentest Web3 applications to protect users from emerging hacking threats.
