# LLM Keys

> How to create, manage, and revoke LLM Keys for the AI Gateway.

## Overview

LLM Keys are API keys that authenticate requests to the Aptible AI Gateway. Each key is scoped to an environment, so you can organize usage across applications, teams, and deployment stages and apply model access policies and cost controls at that level.

A single key gives you access to all models available in that environment. You don't need separate keys per provider. See [Model Access Policies](/ai-gateway/model-access-policies) for more info.

## Creating a Key

Go to the [AI Gateway Dashboard](https://app.aptible.com/llm-keys) and select **Create LLM Key**.

If you're getting set up for the first time, see the [Create your first LLM key](/getting-started/create-your-first-llm-key) guide for a full walkthrough.

## Managing Keys

Keys are managed from the [AI Gateway Dashboard](https://app.aptible.com/llm-keys) in the Aptible dashboard. From the key list you can see each key's name, environment, current period spend, and last used date.

Click into any key to view its details, including request history for the past 7 days, token usage, and per-request costs.

## Revoking a Key

Keys can be revoked from the [AI Gateway Dashboard](https://app.aptible.com/llm-keys). Revoking a key immediately invalidates it. Use this if a key is compromised or you need to permanently cut off access for a specific application or team.
