2fa Authentication

Are there any guides on 2fa authentication with Vaadin and spring security?

Maybe this could help https://www.baeldung.com/spring-security-two-factor-authentication-with-soft-token

Not sure if there are public guides or examples, but I know there is one in works by @poised-leopard

thanks to both of you.
