How to force ssh client to use only password auth?
I recently needed this too, and came up with this:
ssh -o PreferredAuthentications=password -o PubkeyAuthentication=no example.com
You need to make sure that the client isn't configured to disallow password authentication.
I've discovered a shortcut for this purpose:
Note the colon (
:) and the empty password after it.
As well as the method posted by scoopr, you can set per host options in your ssh client configuration file.
.ssh directory, create a file called
config (if it doesn't already exist) and set the permissions to
600, you can then create sections which start with
host <some hostname or pattern>
and then set per host options after that, for example,
host bob.specific.foo user fred host *.home.example user billy port 9191
so you could have
host server.to.test PubkeyAuthentication no
in that file, and then simply
and the option will get picked up.
