[keycloak-dev] Customising Keycloak Authentication flow

[Stian Thorgersen]

Afraid at the moment we don't have any proper way to hook into this, but we are planning to add this in the future.

I'm assuming you're authenticating clients, not users? If so that's something we plan to add support for at some point.

We'll probably add two extension points, one for adding custom login for users (for example a hardware multi-factor auth or even fingerprint scanner) and another for authenticating clients (certificate, jwt, etc.).
