On Linux you can auth using the hash instead of the password. Other OSs probably have something similar.

Yes, but I suppose GPs question was "is that enough to authenticate?" – and given that as you say Linux and iOS/macOS (for Wi-Fi "password" sharing with nearby devices) do support that, and my other comment, the answer is "yes".
