GPT Auth

GPT Auth is an authentication framework designed specifically for GPT-based and LLM-powered applications, enabling developers to add secure, AI-aware user authentication and access control with minimal effort. It provides a structured way to identify users, manage sessions, and enforce permissions directly within conversational or agent-based workflows. The primary purpose of GPT Auth is to bridge traditional auth mechanisms with AI-native interfaces, so authentication becomes a first-class part of your GPT app logic rather than an external afterthought.

GPT Auth typically supports standard authentication flows (such as API key, token, or OAuth-based identity) and exposes them in a form that GPTs and agents can reliably use. It can handle user verification, role and scope assignment, and secure token handling, letting your GPT application know who is speaking and what they are allowed to do before executing sensitive actions. The tool emphasizes consistent, machine-readable responses so that LLMs can interpret auth states (authenticated, unauthorized, insufficient permissions) without ambiguity. This reduces custom glue code and makes it easier to centralize security policies across multiple GPT endpoints or tools.
