The difference is between the sudo and doas programs. sudo does the
following:
--8<---------------cut here---------------start------------->8---
# sudo command
[sudo] password for albinus:
Sorry, try again.
[sudo] password for albinus:
--8<---------------cut here---------------end--------------->8---
And doas does:
--8<---------------cut here---------------start------------->8---
# doas command
doas (albinus@gandalf) password:
doas: Authentication failed
#
--8<---------------cut here---------------end--------------->8---
While sudo asks to reenter the password, doas simply gives up after the
first error. This is what you see in Tramp.
Well, there is a doas issue in its bug tracker to change this behaviour:
<https://github.com/Duncaen/OpenDoas/pull/102>. Once this has arrived
our systems, doas (in Tramp) shall be have like sudo wrt reentering a
wrong password.
I guess we can close this (Tramp) bug.
