Hi, Is it possible to have an application completely open so anyone can log on but uses Passwordless to create user. This is so I don’t have to add them as a user prior to them logging on
Yes you can, by default the passwordless connections allow sign ups, so the users can simply enter their details (email or phone number depending on the type of passwordless connection you are using).
This will create an account for them automatically and they will be given access to your application.
There are some additional steps you will need to carry out to configure the login screen for use with Passwordless too, please see here for more detail - https://auth0.com/docs/dashboard/guides/universal-login/configure-login-page-passwordless
