# User Authentication

It is often required to connect the user's wallet to your application in order to display other parts of the platform or fetch the state for the given user's wallet address.

With the SDK, you don't have to take care of integrating wallet support inside your project.

Simply obtain the SDK instance as explained in [Broken mention](broken://pages/q6IhQCjblvu1bF0ovRgu) section and run following:

{% embed url="<https://codesandbox.io/embed/confident-snow-st5mwn?fontsize=14&hidenavigation=1&theme=dark&view=editor>" %}
Authorization code
{% endembed %}

{% embed url="<https://codesandbox.io/embed/confident-snow-st5mwn?fontsize=14&hidenavigation=1&theme=dark&view=preview>" %}
Authorization example
{% endembed %}

This will return the User object with the wallet address he has connected with. The User returned by our framework has also **proved to own the address** he had connected with.

A full list of the allowed options to configure before an authorization request is generated is explained in the [authorization options docs](/welcome-to-dev3/sdk/user-authentication/options.md).
