Seriously, it’s no more insecure than the checkbox already present in Winbox.
These things are a convenience to keep outsiders from looking over your shoulder, or to keep passwords from showing up in screen shots and videos – not to keep passwords secret from the very administrators who originally set them.

Run Notepad, next run Dude.
On device list or network map select interesting device, then click ‘Copy’ button on Dude toolbar.
Switch to Notepad and paste (Ctrl+V).
You should see whole device configuration including password as XML file. That’s all .
