Re: [JSch-users] Quick question about getting authentication questions

[Cardician <car...@gm...>]

Sorry for a double reply. I had one other question.

Is there any way for me to not have it use this authentication or need the
keys? I've got a username and password on the system I'm SFTPing into so I
don't see why I also need an SSH key. Especially because I just hit enter
and don't actually answer the two Kerberos questions when they're asked. I
just want to SFTP in, provide the username and password, and do my thing.
Not even sure if I'll be able to get access to add keys.

Regardless, thanks for your help.
