# Whitelist System Explained HWID is short for hardware ID, it is a code that represents your computer and is unique. Every time you use Versatile, your HWID is sent to our servers. We use this data to ensure that Versatile isn't being shared among multiple PCs as Versatile can only be used on one PC **at a time.** To allow another PC to run Versatile, you need to **reset your HWID** which you can read in another page below. Currently, we only allow you to reset your HWID every **24 hours**, meaning you can only switch PCs once every day. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
