| 26 | * A conservative <code>UIKeyboardInteractive</code> that avoids real | |
| 27 | * user interaction :). This implementation expects only one prompt with the | |
| 28 | * word password in it. | |
| 29 | * <p/> | |
| 30 | * <code>UIKeyboardInteractive</code> are useful when you don't use user with | |
| 31 | * password authentication with a server that use keyboard-interactive and | |
| 32 | * doesn't allow password method <code>PasswordAuthentication no</code>. | |
