Hi,
When I first started using sdb explorer I just saved my credential without password, it was working fine on that machine but when I used the same copy of sdb explorer on my another machine, it was giving wrong password message during authentication.
What to do? Any help?

You have saved your credential without password option on your machine that was encrypted with your machine name for the security issues. So you could not authenticate, as SDB Explorer is not getting the same machine name by which credential was encrypted.
