To avoid confusion, I shall use the original example provided by Debian Wiki (https://wiki.debian.org/WiFi/HowToUse) which is:

su -l -c "wpa_passphrase myssid my_very_secret_passphrase > /etc/wpa_supplicant/wpa_supplicant.conf"

In a terminal, I typed:

username@hostname:~$ su -l -c "wpa_passphrase JupiterRising 1234567890 > /etc/wpa_supplicant/wpa_supplicant.conf"
Password:
su: Authentication failure

The output is Authentication failure

Best regards.
