I don't know why but this email didn't get delivered to my mailbox even after I'm being in "To" field. I couldn't even find this email in spam. Thankfully, I decided to check debian-users archives and found this mail there!

I went through the links you provided and ended up on systemd-ask-password [0]. As its manpage says, I tried pressing TAB and voila! echo is turned off! Here is the screenshot with echo off [1] BTW, pressing backspace as a very first char worked too (as mentioned in the same manpage). Now I just need to find out from where this `systemd-ask-password` is executed and then edit it's command by omitting the `--echo` flag thereby turning off the echo by default. (A sane default!) Though I'm searching for the `systemd-ask-password` command location; any further help would be really appreciated! Thanks!
