Struct Login 

pub struct Login {
    pub label: String,
    pub start: String,
    pub door: Door,
    pub finish: Option<String>,
    pub next: Option<String>,
    pub enrol: Option<Enrolment>,
}

The door a browser can actually walk through, if there is one.

Fields

label: String

What the button says. The server’s word, not the page’s.

start: String

Where the button goes. A same-site rooted path; the page refuses anything else, so a misconfigured server cannot turn the button into an open redirect.

For Door::Here this is the ceremony’s START path, fetched rather than navigated to.

door: Door

Which of the two doors this is. Defaulted, so an older document still reads.

finish: Option<String>

Door::Here only: where the signed assertion is POSTed. None for a link, and the page treats a Here with no finish as a link, because a ceremony with nowhere to finish is not a ceremony.

next: Option<String>

Door::Here only: where the browser goes once the session cookie is set. A same-site rooted path like the others; None means /.

enrol: Option<Enrolment>

Door::Here only: where the FIRST key is enrolled, when this server offers enrolment on this page at all.

★ A ceremony with no way to enrol a key is one page short of useful. MEASURED on holger.rs 2026-09-20: the button worked, called the door, and the door answered “no passkey is registered yet” — true, and a dead end, because nothing was enrolled and the only place to enrol was a second page again.
