Alternative: Step-by-Step Manual Check

If you prefer to run each check manually:

Check 1: Do you have cookies?

console.log(document.cookie);

Expected: Should include accessToken= and refreshToken=

Check 2: Does backend receive cookies?

fetch('/api/auth/debug-cookies', { credentials: 'include' })
  .then(r => r.json())
  .then(d => console.log(d));

Expected: hasAccessToken: true and hasRefreshToken: true

Check 3: Can you authenticate?

fetch('/api/auth/me', { credentials: 'include' })
  .then(r => r.json())
  .then(d => console.log(d));

Expected: Your user object with username, steamId, etc.

Check 4: Can you get sessions?

fetch('/api/user/sessions', { credentials: 'include' })
  .then(r => r.json())
  .then(d => console.log(d));

Expected: Array of your active sessions

Check 5: Can you setup 2FA?

fetch('/api/user/2fa/setup', { 
  method: 'POST',
  credentials: 'include' 
})
  .then(r => r.json())
  .then(d => console.log(d));

Expected: QR code and secret for 2FA setup

Common Patterns

❌ PATTERN 1: Browser has cookies, backend doesn't receive them

document.cookie → "accessToken=eyJ...; refreshToken=eyJ..."
/api/auth/debug-cookies → hasAccessToken: false

Cause: Cookie domain/secure/samesite mismatch
Fix: Update backend cookie config

❌ PATTERN 2: Everything works except 2FA and sessions

/api/auth/me → ✅ Works
/api/user/sessions → ❌ 401 Unauthorized
/api/user/2fa/setup → ❌ 401 Unauthorized

Cause: Routes not using cookies OR cookie not sent with specific requests
Fix: Check axios config has withCredentials: true

❌ PATTERN 3: Works in DevTools but not in app

fetch('/api/user/sessions', {credentials: 'include'}) → ✅ Works
Vue app call to same endpoint → ❌ Fails

Cause: Axios instance missing withCredentials: true
Fix: Check frontend/src/utils/axios.js

✅ PATTERN: Everything works!

document.cookie → Has accessToken
/api/auth/debug-cookies → hasAccessToken: true
/api/auth/me → ✅ User data
/api/user/sessions → ✅ Sessions array
/api/user/2fa/setup → ✅ QR code

Status: All good! 🎉

What Each Error Means

Error	Meaning	Solution
`No access token provided`	Backend didn't receive cookie	Check cookie domain/secure/samesite
`Access token has expired`	Token timed out (15 min default)	Login again or implement auto-refresh
`User not found`	Token valid but user deleted	Clear cookies and login again
`Invalid access token`	Token corrupted or wrong secret	Clear cookies and login again
`Network Error`	Can't reach backend	Check backend is running on :3000
`CORS Error`	Origin mismatch	Check backend CORS_ORIGIN=http://localhost:5173

Next Steps

Run the main diagnostic script (copy the big script above)
Read the output and identify which check failed
Follow the specific fix for that failure
If still stuck, see TROUBLESHOOTING_AUTH.md for detailed guide
Run backend test: node test-auth.js

Good luck! 🚀
