To create a private app on NotionApps, you need to follow these steps:

### #1 Create a Users database

First, you need to create a Users database. You can skip this step if you've already created one.&#x20;

A users database should have at least two properties. A name property and an email address property.  Every email address present in the Users database can log in to the app.

{% hint style="success" %}
You can duplicate this [Sample Users Database](https://utilizeapp.notion.site/Users-Database-NotionApps-7af55a9e8f33415d93fb0c39134d9a85) to get started.
{% endhint %}

### #2 Link your database to the application

If your Users database is already linked to the application, you may move to step #3. &#x20;

To link your Users database to the application,&#x20;

1. Go to the "Databases" tab in the app builder.
2. Select the desired database.

Newly linked databases could take up to a minute to show up.&#x20;
{% endhint %}

### #3 Configure Users Database for the app

Now, you need to configure your application to select the database your users are pulled from.

1. Go to the "Users" tab.
2. Click on "Select Users Database".
