Pretty cool. Just a heads up, the links in the section: "build your own login, registration, account settings, account verification (e.g. email, phone, activate account), account verification (e.g. reset password) user interfaces and user flows using dead-simple APIs" all are broken, except the 'login' link.

I'm interested in how you allow folks to customize the login flows (probably because my employer, FusionAuth, offers a competitive product :) ). Is this UX customization solely through custom react components?

Is there any ability to customize the actual login sequence, like Azure ADB2C allows? For example: for install A, I want to ask for login, then password, then MFA. for install B, I want to ask for email domain first, then login and password.
