[Suggestion] Asking credentials in an interactive way

[GuillaumeLeclerc]

For the moment we can't say the script is super secure: we have either to put it in a file or to type it in the command line (which is by default saved to .bash_history). Could it be asked in an interactive way so it is not stored anywhere.

For the moment I'm clearing my history every time but I fear some day I will forget it.

Thank you
