Passwords are often entered in HTML pages with a special password field,
derived from text fields. On HTML pages, TAB is applied to jump to the
next text field or anchor. See
<https://en.wikipedia.org/wiki/Tabbing_navigation>. So I doubt that TABs
can be used in passwords.

See also the discussion in the sytemd issue
<https://github.com/systemd/systemd/issues/10100>, where Lennart
Poettering has said something similar about systemd-ask-password.

Yep.
