# How to authenticate in Nebius AI Cloud interfaces

After you [sign up for Nebius AI Cloud](/signup-billing/sign-up), you can work with your resources by using the web console, CLI, Terraform provider or API.

<Tip>
  To get started with the CLI, Terraform and the API, create an [access token](/iam/authorization/access-tokens) for authentication.
</Tip>

## How to sign in to the web console

1. Open the [Nebius AI Cloud web console](https://console.nebius.com).
2. Select the Google, GitHub or Microsoft account that you used to sign up.

   Alternatively, click **Get started with SSO** and specify your [federation ID](/iam/overview#federations).

## How to get started with the CLI

[Install](/cli/install) the Nebius AI Cloud CLI and then [configure it](/cli/configure).

## How to work with Terraform

Follow the [Quickstart](/terraform-provider/quickstart) guide to install and configure the Nebius AI Cloud Terraform provider.

## How to authenticate in the API

Authentication in the API depends on whether you use a service account or a user account. In both cases, you create an access token and include it in the `Authorization` HTTP header. For more information, follow the [authentication guide](/grpc-api/auth).
