How to input SSH password in batch file

Question

I am trying to make a batch file which connects to my router via SSH and executes some commands. The batch file currently looks like:

ssh [email protected]
configure
etc.....

When I run the batch file the first line executes, and then the command window asks

[email protected]'s password:

After inputting the password, the second line does not execute (I imagine this is obvious to someone who knows what they're doing)

I'm looking for a solution that either lets me manually enter the password and then lets the script continue, or one where the script enters the password itself.

How would the remote host (which is not running the script) know what commands are in the script? — SomethingDark

Also, that question may be a duplicate of the question in the title, but it is certainly not a duplicate of the question in the contents. — SomethingDark

Please edit your question to show the relevant parts of your script. I.e., how it invokes ssh and then invokes the commands on the remote system. — Kenster

Try this, which doesn't require any 3rd party tools:

$env:TMPPW=Get-Content -Path 'secure_file.txt'
$j=Start-Job -ScriptBlock{Start-Sleep -Seconds 1;
(New-Object -ComObject wscript.shell).SendKeys("$env:TMPPW{ENTER}")}
Get-Content -Path 'MyScript.txt' | & ssh.exe -q -4 -l user 192.168.1.1
$env:TMPPW=([guid]::NewGuid()).Guid ; $env:TMPPW=$null
