登入畫面就係隨附嘅 signin 片段，按佢嘅各種狀態顯示。最後兩個係俾你複製嘅例子。
每個例子都真係用得，不過入面啲連結唔會帶你去邊度。
signin signin-title live-head
淨係突出一個主要嘅入口，其餘擺喺下面。唔好將註冊同登入分開：一個兩樣都得嘅按鈕，要解釋嘅少，會出錯嘅都少。
一個輸入格，一個掣。冇嘢要記，亦冇嘢可以偷。rastrillo 一開箱就做到。
{{ define "title" }} {{ template "signin-title" (dict "State" .Signin "Brand" .Brand )}} {{ end }}
{{ define "content" }} {{ template "signin" (dict "State" .Signin "Brand" .Brand )}} {{ end }} 瀏覽器會記住上次點樣入嚟。撳一下就會送出記住咗嘅地址，再由頭驗過。
{{ define "title" }} {{ template "signin-title" (dict "State" .Signin "Brand" .Brand )}} {{ end }}
{{ define "content" }} {{ template "signin" (dict "State" .Signin "Brand" .Brand )}} {{ end }} 地址就喺個掣上面，所以乜都唔使打。
{{ define "title" }} {{ template "signin-title" (dict "State" .Signin "Brand" .Brand )}} {{ end }}
{{ define "content" }} {{ template "signin" (dict "State" .Signin "Brand" .Brand )}} {{ end }} 對已經有嘅人嚟講係最快，亦冇嘢要打。但都要俾多一個方法：人會唔見咗部機，而一條用唔到嘅通行密鑰就係一道鎖死咗嘅門。
{{ define "title" }} {{ template "signin-title" (dict "State" .Signin "Brand" .Brand )}} {{ end }}
{{ define "content" }} {{ template "signin" (dict "State" .Signin "Brand" .Brand )}} {{ end }} 將個地址原樣顯示返。喺等一封永遠唔會嚟嘅電郵之前，呢個係唯一發現打錯字嘅機會。
{{ define "title" }} {{ template "signin-title" (dict "State" .Signin "Brand" .Brand )}} {{ end }}
{{ define "content" }} {{ template "signin" (dict "State" .Signin "Brand" .Brand )}} {{ end }} 如果個地址唔係呢個瀏覽器送出嘅，頁面就唔會估佢。
{{ define "title" }} {{ template "signin-title" (dict "State" .Signin "Brand" .Brand )}} {{ end }}
{{ define "content" }} {{ template "signin" (dict "State" .Signin "Brand" .Brand )}} {{ end }} 用一句話講今次寄咗連結，唔會估原因。
{{ define "title" }} {{ template "signin-title" (dict "State" .Signin "Brand" .Brand )}} {{ end }}
{{ define "content" }} {{ template "signin" (dict "State" .Signin "Brand" .Brand )}} {{ end }} 頁面會自己轉過去，萬一冇轉都有條連結。
{{ define "title" }} {{ template "signin-title" (dict "State" .Signin "Brand" .Brand )}} {{ end }}
{{ define "content" }} {{ template "signin" (dict "State" .Signin "Brand" .Brand )}} {{ end }} 個提示屬於嗰個欄位，焦點亦都由嗰度開始。
{{ define "title" }} {{ template "signin-title" (dict "State" .Signin "Brand" .Brand )}} {{ end }}
{{ define "content" }} {{ template "signin" (dict "State" .Signin "Brand" .Brand )}} {{ end }} 個掣會轉做改為寄連結，咁就冇人會卡住。
{{ define "title" }} {{ template "signin-title" (dict "State" .Signin "Brand" .Brand )}} {{ end }}
{{ define "content" }} {{ template "signin" (dict "State" .Signin "Brand" .Brand )}} {{ end }} 我哋俾按鈕你，按每間公司嘅要求畫好。登入本身我哋唔提供：嗰部分你自己接去所用嘅供應商。

rastrillo 冇帶呢個畫面。人會重複用密碼，密碼會外洩，而安全保存嘅工作就落喺你身上。請用電郵連結加通行密鑰，或者淨用通行密鑰。呢度有標記，係因為有啲產品仲需要佢。
