+# Quick Guide: Activate Authentication V2 Fixes
+
+## Step 1: Install Dependency
+```bash
+cd backend
+npm install [email protected]
+```
+
+## Step 2: Add to Docker & Run Migration
+```bash
+# Rebuild Docker with new dependency
+docker-compose down
+docker-compose up -d --build
+
+# Run migration for token revocation
+docker exec wedding-photo-sharing-backend-1 node /app/scripts/add-token-revocation-tables.js
+```
+
+## Step 3: Update server.js
+
+### 3.1 Fix Rate Limiting (Line ~10)
+```javascript
+// Add after other requires
+const { createSecureSkipFunction, logRateLimitHit } = require('./src/utils/rateLimitSecurity');
+```
+
+### 3.2 Update Rate Limiter (Line ~59)
+```javascript
+const limiter = rateLimit({
+  windowMs: 15 * 60 * 1000,
+  max: process.env.NODE_ENV === 'development' ? 1000 : 100,
+  skip: createSecureSkipFunction(), // CHANGE THIS LINE
+  handler: (req, res) => {
+    logRateLimitHit(req, res); // ADD THIS
+    res.status(429).json({
+      error: 'Too many requests from this IP, please try again later.'
+    });
+  }
+});
+```
+
+### 3.3 Update Auth Limiter (Line ~81)
+```javascript
+const authLimiter = rateLimit({
+  windowMs: 15 * 60 * 1000,
+  max: 5,
+  skipSuccessfulRequests: true, // ADD THIS
+  handler: (req, res) => {
+    logRateLimitHit(req, res); // ADD THIS
+    res.status(429).json({
+      error: 'Too many login attempts, please try again later.',
+      retryAfter: res.getHeader('Retry-After')
+    });
+  }
+});
+```
+
+### 3.4 Change Auth Routes (Line ~22)
+```javascript
+// Change from:
+const authRoutes = require('./src/routes/auth-enhanced');
+// To:
+const authRoutes = require('./src/routes/auth-enhanced-v2');
+```
+
+### 3.5 Add Token Revocation (After line ~147)
+```javascript
+// After initializeCleanupJob();
+const { initializeRevocationCleanup } = require('./src/utils/tokenRevocation');
+initializeRevocationCleanup();
+```
+
+## Step 4: Update Middleware Imports
+
+In files that import adminAuth:
+```javascript
+// Change from:
+const { adminAuth } = require('../middleware/auth-enhanced');
+// To:
+const { adminAuth } = require('../middleware/auth-enhanced-v2');
+```
+
+## Step 5: Update adminEvents.js
+
+Add password validation to event creation:
+```javascript
+// At top of file
+const { validatePasswordInContext, getBcryptRounds } = require('../utils/passwordValidation');
+
+// In POST route, after extracting password, add:
+const passwordValidation = validatePasswordInContext(password, 'gallery', {
+  eventName: event_name
+});
+
+if (!passwordValidation.valid) {
+  return res.status(400).json({ 
+    error: 'Password does not meet security requirements',
+    details: passwordValidation.errors,
+    score: passwordValidation.score,
+    feedback: passwordValidation.feedback
+  });
+}
+
+// Change password hashing to:
+const password_hash = await bcrypt.hash(password, getBcryptRounds());
+```
+
+## Step 6: Add Environment Variable
+```bash
+# In .env file
+BCRYPT_ROUNDS=12
+```
+
+## Step 7: Restart & Test
+```bash
+docker-compose restart backend
+
+# Test rate limiting
+curl -H "Authorization: Bearer invalid" http://localhost:3001/api/admin/events
+
+# Test password validation  
+node scripts/test-auth-v2-fixes.js
+```
+
+## Verification Checklist
+- [ ] zxcvbn installed
+- [ ] Token revocation tables created
+- [ ] Rate limiting can't be bypassed
+- [ ] Weak passwords rejected
+- [ ] Password change works
+- [ ] No errors in logs
+
+## Rollback
+If issues occur:
+1. Revert server.js changes
+2. Restart backend
+3. All new features are additive, so existing functionality remains
