What did I just write...

check_set_password.sh

#!/usr/bin/expect -f
set password "PASSWORDGOESHERE"
set r 0

spawn ssh -oStrictHostKeyChecking=no admin@localhost exit
expect "assword:" {
    send "$password\r"
    expect "assword:" {
        set r 1
    }
}

# If we didn't get prompted twice the password should be correct
if {$r == 0} {
    send_user "Password Set Correctly"
    exit 0
}

# If we got prompted twice go ahead and check the other possible account
if {$r == 1} {
    set r 0
    spawn ssh -oStrictHostKeyChecking=no administrator@localhost exit
    expect "assword:" {
        send "$password\r"
        expect "assword:" {
            set r 1
        }
    }
}

# If we didn't get prompted twice the password should be correct
if {$r == 0} {
    send_user "Password Set Correctly"
    exit 0
}

send_user "Password Not Set"
exit 1
