How to disable Splashdot saving passwords?

I'm confused by why Splashdot automatically saves passwords.

I don't want passwords saved, i want to be given my remote computer's login screen, and enter my password directly.

While the "You can log in to this account without entering a password" prompt is handy, I don't want any interim service holding on to my password.

How can i disable this option?

Clicking "Cancel" on the prompt above is not the solution, the password is still there to conveniently log you in the next time you try to connect to the remote.
