Huh? The password is displayed right below the QR code, at least on my Pixel. Must be a difference between Android versions or vendor customizations, which is why I asked.

Apple used to play that security-by-obscurity game too in their implementation of password sharing with nearby devices, and by not allowing users to view passwords in the Wi-Fi settings (even passwords they hand-entered themselves, as if they can't also make a copy of that in a much less secure place at that point). Fortunately, they've come around in the newer iOS versions.
But which Android feature are you referring to? On my Pixel, I can share the PSK as a QR code – not just the hash as far as I can tell.
