Testing Tips

• Add your own Facebook account as a test user under: Roles → Testers
• Make sure your Facebook App is in Live mode (not "In Development") for real users
• Check the browser console or Facebook logs for detailed error messages if login fails

Security Notes

• WuWei uses the official OAuth 2.0 redirect flow
• Passwords are never shared — only Facebook id, email, and name are used
• All data transfer occurs over HTTPS
