store passwords for SSH logins?

[Jeremy C. Reed]

I frequently use ssh-agent to store passwords associated with SSH keys.

But does anyone know of a tool or way to store passwords for SSH logins 
without a key?

I use a SSH server for frequent manual transactions and it is an 
inconvenience for me to re-enter password every time. It is not an option 
for me to setup an SSH key on the server (I don't control it).
