Maybe you are interested in this little PoC I made a while ago which instead sends a one-time-auth code using Matrix: https://loginwithmatrix.tiktalk.space/
It does prove that you own the specific matrix id you are logging in with to the website. It can for example be used as an alternative everywhere where "Sign in with Google" is used, so I don't understand why it should be useless for applications.
