# Remember Me Feature Removal - Implementation Summary
**Date:** 2026-01-12
**Task:** Remove Remember Me feature and implement profile_timeouts priority
**Status:** ✅ **COMPLETE**

---

## Overview

Successfully removed the Remember Me functionality from the application and implemented profile-based session timeouts that override the SESSION_LIFETIME environment variable. This provides better security with granular control over session expiration for different profile types.

---

## Changes Made

### 1. Removed Remember Me Checkbox from Login Views ✅

**Files Modified:**

#### `/resources/views/auth/login.blade.php` (lines 87-94)
**Before:**
```blade
<div class="block mt-4">
    <label for="remember_me" class="flex items-center">
        <x-jetstream.checkbox id="remember_me" name="remember" />
        <span class="ml-2 text-sm text-theme-primary">
            {{ __('Remember me for :period', ['period' => daysToHumanReadable(timebank_config('auth.remember_me_days', 90))]) }}
        </span>
    </label>
</div>

<div class="flex items-center justify-end mt-4 mb-8">
```

**After:**
```blade
<div class="flex items-center justify-end mt-8 mb-8">
```

#### `/resources/views/livewire/login.blade.php` (line 42)
**Before:**
```blade
<form class="mt-8" wire:submit="login">
    <input type="hidden" name="remember" value="true">
    <div class="rounded-md shadow-sm">
```

**After:**
```blade
<form class="mt-8" wire:submit="login">
    <div class="rounded-md shadow-sm">
```

#### `/resources/views/livewire/registration.blade.php` (line 83)
**Before:**
```blade
<form wire:submit="create">
    <input name="remember" type="hidden" value="true">
    @csrf
```

**After:**
```blade
<form wire:submit="create">
    @csrf
```

### 2. Removed remember_me_days from All Config Files ✅

**Files Modified:**

1. `config/timebank_cc.php` - Removed `'remember_me_days' => 90,` from auth section
2. `config/timebank_cc.php.example` - Removed from auth section
3. `config/timebank-default.php` - Removed from auth section
4. `config/timebank-default.php.example` - Removed from auth section

**Before:**
```php
'auth' => [
    'remember_me_days' => 90, // Number of days the "Remember me" checkbox will keep users logged in
    'minimum_registration_age' => 18,
],
```

**After:**
```php
'auth' => [
    'minimum_registration_age' => 18, // Minimum age for registration (GDPR Article 8 compliance)
],
```

---

### 3. Created ProfileSessionTimeout Middleware ✅

**New File:** `app/Http/Middleware/ProfileSessionTimeout.php`

**Purpose:** Enforces profile-specific session timeouts that override SESSION_LIFETIME from .env

**Key Features:**
- Tracks last activity timestamp in session
- Calculates idle time and compares against profile-specific timeout
- Automatically logs out users when timeout is exceeded
- Uses profile_timeouts from platform config
- Falls back to profile_timeout_default if profile type not configured
- Logs timeout events for debugging

**Implementation Highlights:**
```php
// Get profile-specific timeout
$timeoutMinutes = $this->getProfileTimeout($activeProfileType);

// Calculate idle time
$idleMinutes = (now()->timestamp - $lastActivity) / 60;

// Check timeout and logout if exceeded
if ($idleMinutes > $timeoutMinutes) {
    Auth::logout();
    $request->session()->invalidate();
    return redirect()->route('login')
        ->with('status', __('Your session has expired due to inactivity.'));
}
```

---

### 4. Registered Middleware in Kernel ✅

**File:** `app/Http/Kernel.php`

**Change:** Added ProfileSessionTimeout middleware to web middleware group

**Position:** After `StartSession` but before other auth-related middleware

```php
'web' => [
    \App\Http\Middleware\EncryptCookies::class,
    \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
    \Illuminate\Session\Middleware\StartSession::class,
    \App\Http\Middleware\ProfileSessionTimeout::class, // ← NEW
    \Illuminate\View\Middleware\ShareErrorsFromSession::class,
    // ...
],
```

---

### 5. Updated Session Configuration ✅

**File:** `config/session.php`

**Changes:**
1. Updated SESSION_LIFETIME default from 480 to 120 minutes
2. Added comment explaining profile_timeouts override this value

**Before:**
```php
'lifetime' => env('SESSION_LIFETIME', 480),
```

**After:**
```php
/*
| NOTE: This is overridden by profile_timeouts in platform config.
| See config/timebank_cc.php -> 'profile_timeouts' for actual timeouts.
| This value serves as a fallback only.
*/

'lifetime' => env('SESSION_LIFETIME', 120),
```

---

### 6. Updated Platform Config Documentation ✅

**Files:**
- `config/timebank_cc.php`
- `config/timebank_cc.php.example`
- `config/timebank-default.php`
- `config/timebank-default.php.example`

**Section Renamed:** "Profile Inactivity" → "Profile Session Timeouts"

**Enhanced Documentation:**
```php
/*
|--------------------------------------------------------------------------
| Profile Session Timeouts
|--------------------------------------------------------------------------
|
| Define the inactivity timeout in minutes for each profile type.
| After the specified timeout, the user's session will expire and they
| will be logged out automatically. This provides security by ensuring
| inactive sessions are terminated.
|
| IMPORTANT: These timeouts OVERRIDE the SESSION_LIFETIME setting from .env
| They are enforced by ProfileSessionTimeout middleware.
|
| Security Best Practices:
| - User profiles: Short timeout (10-30 min) for regular accounts
| - Organizations: Medium timeout (30-60 min) for community profiles
| - Banks: Short timeout (15-30 min) for financial operations
| - Admins: Very short timeout (15-30 min) for privileged access
|
*/
'profile_timeouts' => [
    App\Models\User::class => 10, // minutes
    App\Models\Organization::class => 60,
    App\Models\Bank::class => 30,
    App\Models\Admin::class => 360, // TODO: change to 30 for production
],
'profile_timeout_default' => 120, // minutes. Fallback default
```

## Current Session Timeout Configuration

### Profile-Specific Timeouts (config/timebank_cc.php)

| Profile Type | Timeout | Duration | Security Level |
|--------------|---------|----------|----------------|
| **User** | 10 min | 10 minutes | High (short for regular users) |
| **Organization** | 60 min | 1 hour | Medium (longer for community work) |
| **Bank** | 30 min | 30 minutes | High (financial operations) |
| **Admin** | 360 min | 6 hours | LOW ⚠️ (TODO: reduce to 30 min) |
| **Default** | 120 min | 2 hours | Fallback |

### Environment Configuration

**File:** `.env`
```
SESSION_LIFETIME=120
```

**Note:** This value is now overridden by profile_timeouts. It serves only as a fallback for the ProfileSessionTimeout middleware.

## Security Improvements

### Before (With Remember Me)

❌ **Problems:**
- Sessions lasted 90 days with Remember Me checkbox
- Users could remain logged in for months
- Increased risk on shared computers
- Privacy policy didn't disclose long sessions
- Single timeout for all profile types

### After (Profile-Based Timeouts)

✅ **Improvements:**
- No long-term authentication tokens
- Profile-specific timeouts (10-360 minutes)
- Automatic logout after inactivity
- Clear session expiration messages
- Better security for financial transactions
- Granular control per profile type

---

## Testing Required

### Test 1: User Session Timeout (10 minutes)
```bash
# 1. Log in as regular user (e.g., user 161)
# 2. Wait 10 minutes without activity
# 3. Try to navigate to any page
# Expected: Automatic logout with "session expired" message
```

### Test 2: Organization Session Timeout (60 minutes)
```bash
# 1. Log in as user, switch to organization profile
# 2. Wait 60 minutes without activity
# 3. Try to navigate to any page
# Expected: Automatic logout after 60 minutes
```

### Test 3: Profile Switch Timeout Behavior
```bash
# 1. Log in as user (10 min timeout)
# 2. Wait 5 minutes
# 3. Switch to organization (60 min timeout)
# 4. Wait 10 more minutes (15 total since login)
# Expected: Still logged in (organization has 60 min timeout)
```

### Test 4: Activity Keeps Session Alive
```bash
# 1. Log in as user (10 min timeout)
# 2. Every 5 minutes, navigate to a page
# 3. Continue for 30 minutes
# Expected: Session remains active because of continuous activity
```

### Test 5: Logout Clears Last Activity
```bash
# 1. Log in as user
# 2. Navigate around (establishes last_activity_at)
# 3. Log out
# 4. Log in again immediately
# Expected: New session starts, last_activity_at reset
```

---

## Database Impact

### Sessions Table

No schema changes required. The middleware stores `last_activity_at` in the session data:

```php
session(['last_activity_at' => now()->timestamp]);
```

### Remember Tokens

The `remember_token` column in the users table will no longer be used by authentication, but doesn't need to be removed (Laravel may use it for other purposes).

## Backward Compatibility

### Breaking Changes ⚠️

1. **Users with active Remember Me tokens** will be logged out after their profile timeout expires (10-360 minutes depending on profile type)

2. **No more 90-day sessions** - Maximum session is now determined by profile_timeouts (currently max 360 minutes for Admins)

3. **Session expiration behavior changed** - Users will experience more frequent logouts based on inactivity

### Migration Notes

**For Users:**
- No data loss
- Will need to log in more frequently
- Better security for their accounts

**For Admins:**
- Update privacy policy to remove Remember Me disclosure
- Monitor user feedback about session timeouts
- Consider adjusting profile_timeouts if needed

---

## Privacy Policy Updates Required

### Remove from Privacy Policy ⚠️

The following sections were added in the previous session and should now be REMOVED:

**From Section 3.4 (Technical Data):**
```markdown
- **Online presence data** (for real-time messaging features)
  - Online/offline status
  - Last seen timestamp
  - Recent activity for presence detection (within 5-minute threshold)
  - Data is automatically deleted after inactivity or when you log out
- **Authentication tokens** (for "Remember Me" feature)  ← REMOVE THIS
  - Optional remember me token (stored for 90 days if enabled)  ← REMOVE THIS
  - Automatically deleted when you log out or token expires  ← REMOVE THIS
```

**From Section 9 (Security):**
```markdown
## Session Security
- Regular sessions expire after 2 hours of inactivity  ← UPDATE THIS
- "Remember Me" feature (optional) keeps you logged in for 90 days  ← REMOVE THIS
  - Use only on trusted personal devices  ← REMOVE THIS
  - Always log out on shared or public computers  ← REMOVE THIS
```

### Update to Say Instead:

**Section 9 (Security):**
```markdown
## Session Security
- Sessions expire automatically based on profile type and inactivity:
  - User profiles: 10 minutes of inactivity
  - Organization profiles: 60 minutes of inactivity
  - Bank profiles: 30 minutes of inactivity
  - Admin profiles: 6 hours of inactivity (to be reduced to 30 minutes)
- Sessions are encrypted and stored securely
- Automatic logout protects your account on shared computers
```

## Known Issues / TODO

### 1. Admin Timeout Too Long ⚠️

**Current:** 360 minutes (6 hours)
**Recommended:** 30 minutes

**File:** `config/timebank_cc.php` line 1413
```php
App\Models\Admin::class => 360, // TODO: change to 30 for production
```

**Action Required:** Update to 30 minutes before production deployment

### 2. User Timeout Very Short

**Current:** 10 minutes
**Consideration:** May be too aggressive for regular users

**Recommendation:** Consider increasing to 30 minutes based on user feedback

### 3. Session Sweep Lottery

The `sessions` table needs periodic cleanup. Laravel's session sweeper runs with lottery odds of 2/100.

**Verify this is running:**
```bash
# Check if old sessions are being cleaned up
mysql -u root -p timebank_cc -e "SELECT COUNT(*) as old_sessions FROM sessions WHERE last_activity < UNIX_TIMESTAMP(DATE_SUB(NOW(), INTERVAL 2 HOUR));"
```
