Ah, I see; yes, one of the benefits of this system over the current IBR system is that multiple different types of challenges can be issued during a registration flow. So a server might present a POW function, then it might present a login form where the user enters their desired username and an email, then it might send an email with a unique code and present another form where they have to enter that code. Or they could do some other combintaion; this would all be a matter of server preference. —Sam _______________________________________________ Standards mailing list Info: https://mail.jabber.org/mailman/listinfo/standards Unsubscribe: [email protected] _______________________________________________
