Input password into SSH without typing

sshpass does not have to show the password in the ps. It might read it an environment variable:

SSHPASS=12345 sshpass -e ssh user@host

or from a file:

sshpass -f /path/to/password_file ssh user@host

My sshpass has an option -f to read from a file. So with bash process substitution you can do

sshpass -f <(myscript_call_1password) ssh host
