# Access from the Internet Learn how to expose a local FusionAuth instance to the internet. > For the index of this section of the site, see [llms.txt](https://fusionauth.io/docs/llms.txt) FusionAuth lets you develop locally with a full featured auth system. To do so, [install FusionAuth](https://fusionauth.io/docs/get-started/install.md) using one of the options, such as Homebrew or a .deb file. There are situations where you want to expose your local FusionAuth instance to the internet. Some examples include: * debugging an integration with an external system * trying to show your custom themes to a developer on your team in a different office * verifying the behavior of cookies over a secure connection without setting up certificates * testing your login pages on a different device such as a phone or tablet To help with these situations, use `ngrok`. This tool exposes your local FusionAuth instance and gives it a publicly accessible URL. To set up `ngrok`, do the following: * [download and install ngrok](https://ngrok.com/download) (free registration required) * start your FusionAuth instance * run `ngrok`: `ngrok http --request-header-add 'X-Forwarded-Port:443' 9011` You need the request header argument to avoid proxy issues from FusionAuth. You'll then see a screen similar to this. ```plaintext ngrok (Ctrl+C to quit) Add Okta or Azure to protect your ngrok dashboard with SSO: https://ngrok.com/dashSSO Session Status online Session Expires 1 hour, 59 minutes Terms of Service https://ngrok.com/tos Version 3.1.0 Region United States (us) Latency 58ms Web Interface http://127.0.0.1:4040 Forwarding https://627d-131-226-35-36.ngrok.io -> http://localhost:9011 Connections ttl opn rt1 rt5 p50 p90 0 0 0.00 0.00 0.00 0.00 ``` If you are exposing a local web application as well as FusionAuth using `ngrok`, make sure you update your **Authorized redirect URLs** in the Application configuration. ## Security Considerations Doing this gives anyone on the internet a path to your local machine, if they know the URL. Shut this down when it has served its purpose.
