I have key-pairs to ssh and scp into a server without entering my password. There are numerous tutorials on this, e.g.
I would like to now set up an environment whereby this key-pair doesn't exist for some debugging. I don't want to delete they key-pair I already have though, because that's a pain. It's requires much deleting/resetting of keys in
~/.ssh/id_rsa.pub, of which I have many.
Is it possible to ssh into the server in such a way such that the key-pair will be ignored? Is there a convenient way to enter in a "blank slate" for debugging connection issues?
