By default, the juju login command logs the user into a controller. The argument to the command can be a public controller host name or alias (see Aliases below).

If no argument is provided, the controller specified with the -c argument will be used, or the current controller if that’s not provided.

On success, the current controller is switched to the logged-in controller.

If the user is already logged in, the juju login command does nothing except verify that fact.

If the -u option is provided, the juju login command will attempt to log into the controller as that user.

After login, a token (“macaroon”) will become active. It has an expiration time of 24 hours. Upon expiration, no further Juju commands can be issued and the user will be prompted to log in again.


Public controller aliases are provided by a directory service that is queried to find the host name for a given alias. The URL for the directory service may be configured by setting the environment variable JUJU_DIRECTORY.
