I know it is not recommended, but is it at all possible to pass the user's password to scp?
I'd like to copy a file via scp as part of a batch job and the receiving server does, of course, need a password and, no, I cannot easily change that to key-based authentication.

You can publish your docs via SSH through a Terminal window or more likely, via a shell script that you simply execute as part of the publishing process. However, you will be prompted for your password with each file transfer unless you configure passwordless SSH.
sshpass is a useful tool used for running ssh authentication in non-interactive mode. Using sshpass you can use passwords to ssh or scp command without interactions, which helps to utilize in shell scripts.
Use sshpass:
sshpass -p "password" scp -r [email protected]:/some/remote/path /some/local/path
or so the password does not show in the bash history
sshpass -f "/path/to/passwordfile" scp -r [email protected]:/some/remote/path /some/local/path
The above copies contents of path from the remote host to your local.
Install :
apt install sshpassyum install sshpassport install sshpassbrew install https://raw.githubusercontent.com/kadwanev/bigboybrew/master/Library/Formula/sshpass.rb

just generate a ssh key like:
ssh-keygen -t rsa -C "[email protected]"
copy the content of ~/.ssh/id_rsa.pub
and lastly add it to the remote machines ~/.ssh/authorized_keys
make sure remote machine have the permissions 0700 for ~./ssh folder and 0600 for ~/.ssh/authorized_keys

If you are connecting to the server from Windows, the Putty version of scp ("pscp") lets you pass the password with the -pw parameter.
This is mentioned in the documentation here.
