    There are some opensource solutions that are trying to solve this issue; one of them is Keycloak. Keycloak solves this problem well but introduces some other problems: It is very complex and custom styling is everything but easy if you want to use something like Next.js to fully integrate the Login/Registration into your webapp.

    In order to get an idea how to create an authenticator (or any other class you might need that leverages SPI for that matter) I recommend taking a look at Keycloak source code hosted on GitHub - As you might expect Keycloak has a very large codebase therefore it would be easier to use GitHub search to find the class you might need. In our case you may find authenticators directory interesting - I will not go into detail about existing Keycloak authenticators and their implementations and rather start scaffolding our own authenticator.

    Keycloak is an open-source Identity and Access Management solution. I find it very useful for small to large teams that need to implement their own authentication system but do not have the capacity to develop a secure service themselves. It is written in Java and offers an SPI (Service Provider Interface). This means that it is easily extendable with custom implementations of existing classes and new additions via plugins.
