Use the [Google Assistant Service](/assistant/sdk/guides/service/python) instead.\n\n\u003cbr /\u003e\n\nHere are some security and privacy guidelines for developers using the Google\nAssistant API in their projects.\n\nAPI and application authorization\n---------------------------------\n\nAny application that uses the Google Assistant API must have authorization\ncredentials that identify the application to Google's authentication server.\nTypically, these credentials are stored in a downloaded `client_secret_\u003cclient-id\u003e.json`\nfile. Make sure to store this file in a location that only your application\ncan access.\n\nYour application may prompt the user to grant it access to their Google account.\nIf granted, your application can request an access token for that user. These\ntokens expire, but can be refreshed.\n\nUnprotected refresh tokens on a device pose a significant security risk. Make\nsure your application:\n\n- Stores the refresh tokens in a secure place.\n- Provides an easy way to clear tokens from the device. For example, provide a \"Sign out\" button that clears a token (if the application has a UI) or a command line script that the user can execute.\n- Informs users that they can [deauthorize access](https://myaccount.google.com/permissions) to their Google account. This revokes the refresh token; to use the application again, the user would need to re-authorize access.\n\nWhen you are done using the device permanently, you should clear all of the\ntokens from it.\n\nFor more information, see [Using OAuth 2.0 to Access Google APIs](https://developers.google.com/identity/protocols/OAuth2)."]]
