Hi Michael and thanks for your research,

I had a look at this PR and it proposed to integrate a patch from
upstream doas (which is into the OpenBSD tree) that dates back to
september 2021.  I'm using TRAMP to access recent OpenBSD systems (7.3)
and this patch is already here.  Here's what I get by default (doas asks
for password 3 times):

$ doas -s
doas (manuel@computer) password: 
doas: Authentication failed
doas (manuel@computer) password: 
doas: Authentication failed
doas (manuel@computer) password: 
doas: Authentication failed
$

So I think that TRAMP needs to take this into account.

Best regards,
