Can anyone who has used and understands Gnome-keyring please tell me how it works before I install it?

I've got one program that always says it wont save any passwords because Gnome-keyring is not installed or is not accessible.

But I am a little weary because the LIMITED info on the net says that it might also store SSH passwords and I really don't want to do that.

So one question is, does Gnome-keyring have some sort of GUI where you can configure it?

Another is, can I configure it to not accept password requests from certain programs?

Will it interfere with KDE Wallet?
