This command logs you out. In practice, it will delete all tokens stored on your machine. If you want to remove a specific token, you can specify the token name as an argument.  
This command will not log you out if you are logged in using the `HF_TOKEN` environment variable (see [reference](../package_reference/environment_variables#hftoken)). If that is the case, you must unset the environment variable in your machine configuration.
