LUKS password gets printed as stars

[root kea <rootkea@gmail.com>]

Hello!

I am using LUKS on LVM on Debian Stretch. I have encrypted /home and
swap partition. When initram gets loaded it asks for password to
decrypt swap partition. That passowrd doesn't get printed to screen.
No stars. Nothing.

But After which Kernel gets loaded (I think) and it asks password for
/home which gets printed as stars. I'm really worried about this. Here

How do I prevent those stars from getting printed on the screen?

PS - while replying please CC me as I'm not subscribed to debian-users.

Thank you.
