Agreed; using a password that's embedded into the script is worse than
useless. The same goes for sudo passwords, if that's a thing; arrange
it so the user that you SSH in as has the power to run that command
without a password (you can do that in the sudoers file, even if it
needs a password for all other usage).

If necessary, create a dedicated SSH keypair *just* for this script.
It's still easier to protect an SSH private key than a password.
