# Technical Design Spec: Auth-Yes Mobile-First & Modern Minimalist UI Revamp
**Date:** 2026-08-24\
**Author:** Tyler Gillispie & Antigravity\
**Status:** Approved by User\
**Scope:** Frontend UI & SSR Layouts (`ui/`)
---
## 1. Executive Summary & Objectives
Auth-Yes provides an ultra-low-friction IAM and WebAuthn Passkey authority. The
goal of this technical revamp is to modernize the user interface with a
**mobile-first, modern minimalist design** that feels native and thumb-friendly
on smartphones while remaining clean, responsive, and spacious on desktop
browsers.
### Key Objectives:
1. **Ergonomic Mobile Navigation**: Implement a fixed, thumb-accessible bottom
navigation bar on mobile (`< 768px`) with `env(safe-area-inset-bottom)`
support.
2. **Instant Biometric Login**: Transform the login experience to prioritize
one-tap passkey biometric authentication with WebAuthn conditional UI
autofill, moving USB/username clutter behind progressive disclosure.
3. **Adaptive Card Decks**: Eliminate rigid desktop-style tables on mobile
devices for Sessions, Passkeys, and Admin screens in favor of responsive,
touch-friendly card lists.
4. **Zero-Dependency Purity**: Maintain 100% pure Hono SSR JSX and vanilla CSS
with zero client-side framework runtime bloat.

## 2. Visual Design System & Theme Foundation
### 2.1 CSS Custom Properties (Design Tokens)
The stylesheet will be embedded globally via the root layouts using standard CSS
custom properties:
```css

## 3. Shell Architecture & Navigation
### 3.1 Adaptive Layout Structure
```
+-------------------------------------------------------------+
| MOBILE VIEW (< 768px) |
+-------------------------------------------------------------+
| [⚡ Auth-Yes] Launchpad [tylerg] [🚪Logout] | <-- Compact Top Bar
+-------------------------------------------------------------+
| |
| (Main Content Area - Adaptive Cards & Tiles) |
| |
+-------------------------------------------------------------+
| [ 🚀 Launchpad ] [ 📱 Sessions ] [ 🔑 Passkeys ] [ 🛡️ Admin ] | <-- Fixed Bottom Nav
+-------------------------------------------------------------+
```
```
+-------------------------------------------------------------+
| DESKTOP VIEW (≥ 768px) |
+-------------------------------------------------------------+
| [⚡ Auth-Yes] Launchpad Sessions Passkeys [Admin] [Logout] | <-- Sticky Top Bar
+-------------------------------------------------------------+
| |
| (Main Content Area - Wide Container & Tables) |
| |
+-------------------------------------------------------------+
```
### 3.2 Navigation Components
1. **`ui/components/AuthenticatedLayout.tsx`**:
- On screens `< 768px`: Renders a fixed bottom navigation bar with 4 primary
targets:
- **Launchpad**: `/dashboard`
- **Sessions**: `/dashboard/sessions`
- **Passkeys**: `/dashboard/passkeys`
- **Admin Console**: `/admin/users` (visible when `isAdmin === true`)
- Bottom padding on `<main>` container dynamically set to
`calc(4rem + env(safe-area-inset-bottom))` to prevent content overlap.
- On screens `≥ 768px`: Hides the bottom navigation bar and renders the top
horizontal navigation pill strip.
2. **`ui/components/AdminLayout.tsx`**:
- Sub-navigation across Admin modules (_Users_, _Invites_, _Apps_, _Roles_,
_Audit Logs_, _AAGUIDs_) rendered as a horizontal scrollable pill bar on
mobile and clean tab bar on desktop.
---
## 4. Authentication Flow & Ergonomics
### 4.1 Login Screen (`ui/components/LoginPage.tsx`)
- **Primary Hero**: Large 52px button: **"Sign In with Passkey"** with biometric
fingerprint glyph.
- **Conditional UI / Autofill**: Script initializes
`SimpleWebAuthnBrowser.startAuthentication({ ... }, true)` with
`mediation: 'conditional'` if supported by browser.
- **Progressive Disclosure**: USB instructions and optional username input
collapsed behind an expandable trigger: _"Need to specify a username or use
account recovery?"_.
- **Live State**: Smooth spinner and subtle pulsing aura while authenticator
prompt is active.
### 4.2 Registration Screen (`ui/components/RegisterPage.tsx`)
- Clean 2-step onboarding card for invite-code validation + 1-tap passkey
enrollment.
- 12-word recovery phrase presented with single-tap "Copy Seed Phrase" button.
### 4.3 Recovery Screen (`ui/components/RecoveryPage.tsx`)
- Mobile-friendly 12-box input matrix supporting paste-all and auto-focus
advance.
---
## 5. Adaptive Data Views
### 5.1 Application Launchpad (`ui/components/AppLaunchpadPage.tsx`)
- Responsive grid (1 column on mobile, minmax(320px, 1fr) on desktop).
- Card elements: App Name, Domain link, Role Badge (`Admin` / `Member` /
`Viewer`), description, and prominent 48px **"Launch App ↗"** button.
### 5.2 Sessions Management (`ui/components/SessionsPage.tsx`)
- **Mobile Cards**: Replaces rigid table with session cards showing:
- Device type icon (📱 Phone / 💻 Laptop).
- Emerald **"Current Device"** pill.
- IP Address and formatted date.
- Dedicated **"Revoke Session"** button.
- Top Action: **"Revoke All Other Sessions"** danger button.
### 5.3 Passkeys Management (`ui/components/PasskeysPage.tsx`)
- **Mobile Cards**: Replaces rigid table with passkey cards showing:
- Authenticator vendor brand chip (Google Password Manager, Apple Keychain,
YubiKey).
- Nickname and Credential ID preview.
- Creation and last-used dates.
- 1-tap "Add New Passkey" hero action button.
- Revoke / Delete action.
### 5.4 Admin Screens (`ui/components/Admin*.tsx`)
- Responsive cards for Users, Apps, Invites, and Audit Logs on mobile with
search filters and expandable details.

## 6. Implementation & Quality Gates
1. **Pure SSR JSX**: All changes strictly implemented in Hono SSR JSX without
React runtime.
2. **Quality Gates**:
- `deno fmt`
- `deno task lint`
- `deno task check`
- `deno task test`
