+**🚨 WARNING 🚨**
+
+Disabling authentication with `DANGEROUSLY_OMIT_AUTH` is incredibly dangerous! Disabling auth leaves your machine open to attack not just when exposed to the public internet, but also **via your web browser**. Meaning, visiting a malicious website OR viewing a malicious advertizement could allow an attacker to remotely compromise your computer. Do not disable this feature unless you truly understand the risks.
