Safe is relevant to how secure you need your environment/data to be. It's "safer" or more secure to use keys only, but if you don't have stringent security requirements then password authentication might be acceptable. If somebody is going to brute force you, then it's easier to break an eight character password than a potentially much longer passphrase. Other options also are relevant to your security requirements. Therefore, you need to weight the usage effect of being more secure versus the need for the security. Bo Jacobsen wrote:
I think it's much more convinient to use "Password Authentication" then using keys, but how safe is it.
Also should I use ChallengeResponseAuthentication" or not.
I use SuSE 8.2.
Thanks in advance Bo Jacobsen
