Authentication

The huggingface_hub library allows users to programmatically manage authentication to the Hub. This includes logging in, logging out, switching between tokens, and listing available tokens.

For more details about authentication, check out this section.

login

huggingface_hub.login

< >

( token: str | None = None add_to_git_credential: bool = False skip_if_logged_in: bool = True )

Parameters

  • token (str, optional) — User access token to generate from https://huggingface.co/settings/token.
  • add_to_git_credential (bool, defaults to False) — If True, token will be set as git credential. If no git credential helper is configured, a warning will be displayed to the user. Only used when token is provided; ignored by the browser-based flow.
  • skip_if_logged_in (bool, defaults to True) — If True, do not prompt for token if user is already logged in. Set to False to force re-login. In CLI, use --force instead.

Raises

ValueError or DeviceCodeError

  • ValueError — If an organization token is passed. Only personal account tokens are valid to log in.
  • ValueError — If token is invalid.
  • DeviceCodeError — If the browser-based login fails (authorization denied, code expired, …).

Login the machine to access the Hub.

The token is persisted in cache and set as a git credential. Once done, the machine is logged in and the access token will be available across all huggingface_hub components. If token is not provided, a browser-based OAuth flow is used to authenticate: open a URL, enter a short code, and the token is retrieved and saved. In a terminal, you can also choose to paste an existing access token instead.

To log in from outside of a script, one can also use hf auth login which is a cli command that wraps login().

When the token is not passed, login() will automatically detect if the script runs in a notebook or not. However, this detection might not be accurate due to the variety of notebooks that exists nowadays. If that is the case, you can always force the UI by using notebook_login() or interpreter_login().

interpreter_login

huggingface_hub.interpreter_login

< >

( skip_if_logged_in: bool = True )

Parameters

  • skip_if_logged_in (bool, defaults to True) — If True, do not prompt for token if user is already logged in. Set to False to force re-login. In CLI, use --force instead.

Displays a prompt to log in to the HF website and store the token.

This is equivalent to login() without passing a token when not run in a notebook. interpreter_login() is useful if you want to force the use of the terminal prompt instead of a notebook flow.

For more details, see login().

notebook_login

huggingface_hub.notebook_login

< >

( skip_if_logged_in: bool = True )

Parameters

  • skip_if_logged_in (bool, defaults to True) — If True, do not prompt for token if user is already logged in. Set to False to force re-login. In CLI, use --force instead.

Displays a prompt to log in to the HF website and store the token.

This is equivalent to login() without passing a token when run in a notebook. notebook_login() is useful if you want to force the use of the notebook flow instead of a prompt in the terminal.

For more details, see login().

logout

huggingface_hub.logout

< >

( token_name: str | None = None )

Parameters

  • token_name (str, optional) — Name of the access token to logout from. If None, will log out from all saved access tokens.

Raises

ValueError

  • ValueError — If the access token name is not found.

Logout the machine from the Hub.

Token is deleted from the machine and removed from git credential.

auth_switch

huggingface_hub.auth_switch

< >

( token_name: str add_to_git_credential: bool = False )

Parameters

  • token_name (str) — Name of the access token to switch to.
  • add_to_git_credential (bool, defaults to False) — If True, token will be set as git credential. If no git credential helper is configured, a warning will be displayed to the user. If token is None, the value of add_to_git_credential is ignored and will be prompted again to the end user.

Raises

ValueError

  • ValueError — If the access token name is not found.

Switch to a different access token.

auth_list

huggingface_hub.auth_list

< >

( )

List all stored access tokens.
