I think this only works in limited versions of these auth systems. If that’s what you want, great. Some packages for various languages already exist for this purpose. They’re incomplete auth systems, though. There are more modes of authentication than logging a user into a system or referencing their proof of authentication after login. It’s certainly the most common use case, but authentication can occur using other forms of proof that you’re willing to trust. For example, someone in your system invites people to do something via email. Once these people authenticate by entering a code sent to their email address, you trust that they can access a file based on a cookie you’ve set. However, they are not logged in because they don’t have an account. You would not do this with a login system. You’d do it with an authentication system.
