+# Deployment Checklist - Security Fix
+
+## Pre-Deployment
+
+- [ ] Review all changes in `SECURITY_FIX_SUMMARY.md`
+- [ ] Verify backend is setting httpOnly cookies on login
+- [ ] Test login flow in development environment
+- [ ] Test 2FA flow in development environment
+- [ ] Test wallet operations (mint, burn, send)
+- [ ] Verify no API keys in sessionStorage (DevTools)
+- [ ] Check CSP headers in browser DevTools Network tab
+
+## Deployment Steps
+
+1. [ ] Deploy backend changes first (if any cookie configuration needed)
+2. [ ] Deploy frontend changes
+3. [ ] Clear all user sessions (users will need to re-login)
+4. [ ] Monitor error logs for authentication issues
+
+## Post-Deployment Verification
+
+- [ ] Login works correctly
+- [ ] Logout clears session
+- [ ] 2FA flow works
+- [ ] Wallet operations work
+- [ ] API requests succeed with cookies
+- [ ] CSP headers are present
+- [ ] No console errors related to auth
+- [ ] Check sessionStorage in DevTools - should NOT contain:
+  - `acbu_api_key`
+  - `acbu_passcode`
+
+## Rollback Plan
+
+If issues occur:
+1. Revert frontend deployment
+2. Users may need to clear cookies and re-login
+3. Check backend logs for cookie-related errors
+
+## Security Verification
+
+Run these checks in browser DevTools:
+
+```javascript
+// Should return null (no API key in sessionStorage)
+sessionStorage.getItem('acbu_api_key')
+
+// Should return null (no passcode in sessionStorage)
+sessionStorage.getItem('acbu_passcode')
+
+// Check cookies in DevTools:
+// - Open DevTools > Application > Cookies
+// - Or check Network tab > Headers > Set-Cookie
+// - Look for httpOnly session cookie (cannot be read via document.cookie)
+```
+
+## Files Changed
+
+- `contexts/auth-context.tsx` - Removed API key storage
+- `lib/api/client.ts` - Removed Bearer token auth
+- `app/auth/signin/page.tsx` - Updated login flow
+- `app/auth/2fa/page.tsx` - Updated 2FA flow
+- `lib/passcode-manager.ts` - NEW: In-memory passcode storage
+- `lib/wallet-storage.ts` - Use in-memory passcode
+- `middleware.ts` - NEW: CSP and security headers
+
+## Support
+
+If users report issues:
+1. Ask them to clear cookies and sessionStorage
+2. Ask them to log in again
+3. Check if they can complete wallet operations
+4. Verify CSP isn't blocking legitimate scripts
