Authentication using Azure Databricks personal access tokens

In this article

To authenticate to and access Databricks REST APIs, you can use Azure Databricks personal access tokens or Azure Active Directory (Azure AD) tokens.

This article discusses how to use Azure Databricks personal access tokens. For Azure AD tokens, see Authenticate using Azure Active Directory tokens.

Important

Tokens take the place of passwords in an authentication flow, and like passwords, they should always be treated with care. To protect tokens, Databricks recommends that you store tokens in:

Requirements

Token-based authentication is enabled by default for all Azure Databricks accounts launched after January 2018. If it is disabled, your administrator must enable it before you can perform the tasks described in this article. See Manage personal access tokens.

Generate a personal access token

This section describes how to generate a personal access token in the Azure Databricks UI. You can also generate and revoke tokens using the Token API.

  1. Click the user profile icon User Profile in the upper right corner of your Azure Databricks workspace.

  2. Click User Settings.

  3. Go to the Access Tokens tab.

    List_Tokens

  4. Click the Generate New Token button.

  5. Optionally enter a description (comment) and expiration period.

    Generate_Token

  6. Click the Generate button.

  7. Copy the generated token and store in a secure location.

Revoke a personal access token

This section describes how to revoke personal access tokens using the Azure Databricks UI. You can also generate and revoke access tokens using the Token API.

  1. Click the user profile icon User Profile in the upper right corner of your Azure Databricks workspace.
  2. Click User Settings.
  3. Go to the Access Tokens tab.
  4. Click x for the token you want to revoke.
  5. On the Revoke Token dialog, click the Revoke Token button.

Use a personal access token to access the Databricks REST API

You can store a personal access token in .netrc and use in curl or pass it to the Authorization: Bearer header.

Store token in .netrc file and use in curl

Create a .netrc file with machine, login, and password properties:

machine <databricks-instance>
login token
password <personal-access-token>

where:

  • <databricks-instance> is the workspace URL of your Azure Databricks deployment.
  • token is the literal string token
  • <personal-access-token> is the value of your personal access token.

To invoke the .netrc file, use -n in your curl command:

curl -n -X GET https://<databricks-instance>/api/2.0/clusters/list

Pass token to Bearer authentication

You can include the token in the header using Bearer authentication. You can use this approach with curl or any client that you build. For the latter, see Upload a big file into DBFS.

curl -X GET -H 'Authorization: Bearer <personal-access-token>' https://<databricks-instance>/api/2.0/clusters/list
