# Getting started

### Creating a tenant

If you already have a tenant to be used, you can skip to the [next section](https://www.notion.so/Setting-up-Auth0-8b9d86fabcb14bbdbf4b8848a3458793?pvs=21).

After signing in to your Auth0 account, on the top left corner click on the dropdown button and select <mark style="color:red;">`Create tenant`</mark>

Once it’s created, it should redirect to your app’s <mark style="color:red;">Quick Start</mark> tab. Go to the <mark style="color:red;">Settings</mark> tab of your application and fill the following fields under <mark style="color:red;">`Application URIs`</mark>.

### Additional customizations

Still under the <mark style="color:red;">`Settings`</mark> tab, you can add a logo that will be used on the default pages used by Auth0 (Login, Reset Password, etc.).

A link from an asset uploaded to BF could be used here.
