Mender-cli login failure

Hi!

when I try to login to mender using the mender-cli It fails (No request for password was asked)

   $ mender-cli login --server https://hosted.mender.io --username $USERNAME          
   No configuration file found
   FAILURE: No password set

I need to explicitly add the password like this

$ mender-cli login --server https://hosted.mender.io --username $MENDER_IO_USERNAME --password $PASSWORD
  No configuration file found
  login successful

Is this behavior normal since in the doc it doesn’t mention the need to add --password in the command line?
