Fortinet: How can you view the decrypted passwords in a config? (Open)

Once in a while you configure a device with some passwords for HA, pre-shared keys and more and you did not correctly apply the passwords that you did generate before actually configuring the device. But it's running and then you need to know what it is. With Fortinet I do not understand how to view the configuration with the passwords in clear. With Cisco you can just run a more startup-config (with either flash:/ or disk:/ prefix).
