scp option to send password rather than key pair

I'm trying to scp a file from my ltm to solarwinds scp server (free one right now). It appears that solarwinds does not allow the key pair exchange as would be normal operation. So I'm curious if there is a way to pass the scp line the password. I'm doing this in a script so manual input is not an option. I see there is a [-F ssh_config] and [-o ssh_option] options, but i'm not able to find out what info is accepted here.

Thanks!
