always focus passwords prompts

[Jaime Pérez]

Sometimes (when opening chromium and being asked for password) I start to type the password and I lose focus sudently by another app. This can be used to steal passwords making an application to gain focus when a password prompt is opened. It would be better to allow change focus only clicking twice on another place, so it can't be changed by accident, what would make that password became visible on the terminal, for example.
