## OAuth Providers

All providers show as buttons:

```
┌──────────────┬──────────────┐
│ 🔍 Google    │ 🐙 GitHub    │
└──────────────┴──────────────┘

┌──────────────┬──────────────┐
│ 👍 Facebook  │ 💬 Discord   │
└──────────────┴──────────────┘
```

Each button:
- Shows provider brand colors/logos
- 2-column grid layout
- Hover effects with border colors
- Click redirects to provider login

---

## Configuration

OAuth providers are configured via Admin:
- **URL**: `http://localhost:3001/admin/setup`
- **Section**: "OAuth Providers (BetterAuth)"
- Each provider can be enabled/disabled
- Enter Client ID and Client Secret

Once configured:
- OAuth buttons appear automatically
- No page refresh needed
- Users can immediately use them

## Troubleshooting

### Problem: OAuth buttons don't show
**Solution**: 
- Go to /admin/setup
- Check if providers are enabled
- Ensure Client ID/Secret are filled
- Refresh page

### Problem: "Sign In" button redirects wrong
**Solution**:
- Check redirect parameter in URL
- Default is /account/webinars
- Use `?redirect=/desired/url` to change

### Problem: Password validation fails
**Solution**:
- Must be 8-20 characters
- Need uppercase letter (A-Z)
- Need number (0-9)
- No spaces allowed

### Problem: OAuth redirects to blank page
**Solution**:
- OAuth might be processing in background
- Wait a few seconds
- Check browser console for errors
