Title: fix auth small issue + in case you change your password on index.io

Currently if you change your password on index.docker.io, the only way to have docker working is to remove the *.dockercfg* file

I propose to always ask the password on `docker login`, even if it's the same username, like this you can update the .dockercfg file to the new password.
