Authentication: passwordless-id/connect
Pavlos Vinieratos
https://github.com/passwordless-id/connect is using the new safari thing where it can auth a user using face id, touch id, etc.
https://dev.to/dagnelies/passwordless-authentication-for-your-website-in-5-minutes-1c31 heres a good example of it.
PS. its still not a production ready thing.
