# Password Protection Setup (No HF Account Required)

## ✅ Solution: Gradio Built-in Authentication

**Good news**: You don't need to build your own frontend! Gradio has built-in password protection that works without Hugging Face accounts.

## How It Works

- Users visit your Space URL
- They see a login screen (username/password)
- No Hugging Face account needed!
- Simple and secure

## Setup Steps

### Step 1: Update app.py

The code is already updated! Just change the password:

```python
demo.launch(
    auth=("starflow", "your-password-here"),  # Change this!
    share=False
)
```

### Step 2: Set Your Password

1. **Edit app.py** in your Space (or locally and push)
2. **Change**: `"your-password-here"` to your actual password
3. **Save and push**

### Step 3: Share Access

**Option A: Single Username/Password**
```python
auth=("starflow", "my-secure-password")
```
- Everyone uses same login
- Simple to share

**Option B: Multiple Users**
```python
auth=[
    ("user1", "password1"),
    ("user2", "password2"),
    ("user3", "password3")
]
```
- Different login for each person
- More control

## Usage

1. **Make Space Public** (so anyone can access the URL)
   - Settings → Visibility → Public
   - Or keep Private (only collaborators see it)

2. **Share the Space URL**:
   - https://huggingface.co/spaces/GlobalStudio/starflow

3. **Users visit URL**:
   - See login screen
   - Enter username/password
   - No HF account needed!
   - Access granted ✅

## Security Tips

- ✅ Use strong passwords
- ✅ Change password regularly
- ✅ Don't share password publicly
- ✅ Use different passwords for different users (if using multiple)

## Alternative: Environment Variables (More Secure)

For better security, use environment variables:

```python
import os

username = os.getenv("STARFLOW_USERNAME", "starflow")
password = os.getenv("STARFLOW_PASSWORD", "default-password")

demo.launch(auth=(username, password))
```

Then set in Space Settings → Variables:
- `STARFLOW_USERNAME` = your-username
- `STARFLOW_PASSWORD` = your-password

## Benefits

✅ **No HF account needed** - Users just need password
✅ **Simple** - Built into Gradio
✅ **Secure** - Password protected
✅ **Easy to manage** - Change password anytime
✅ **No custom frontend** - Uses existing Gradio UI

## Summary

**You DON'T need to build your own frontend!**

Just:
1. Add password to app.py
2. Make Space Public (or keep Private + share URL)
3. Share URL + password with users
4. Done! ✅
