How to Use Session Codes for Quick Guest Access

Session codes let you give a remote viewer temporary access to your machine without sharing your permanent VNC password. The code expires automatically.

When to use session codes

• A colleague needs one-time access to help you
• A support technician needs to connect but you don't want to give a permanent password
• You want to let someone in for a limited time window

Step 1: Configure the expiry

In Security → Session Codes, set the Code Expiry in seconds. The default is 120 seconds (2 minutes). You can set it from 30 seconds to 1 hour.

Step 2: Generate a code

On the Dashboard, find the Quick Session Code card. Click Generate Code.

A 6-character alphanumeric code appears — for example AX7K2M. Copy it with the copy button.

Step 3: Share the code

Send the code to the other person via phone, chat, or email. Tell them to:

1. Open their VNC viewer
2. Connect to your IP address and port (shown in Connection Info)
3. Enter the session code as the password

Step 4: The code expires

The code becomes invalid after the configured expiry time, or after use. You cannot reuse a session code. Generate a new one each time.

Tips

• Combine session codes with window-only sharing for maximum privacy — the viewer can only see one app and can only connect temporarily
• Generate the code right before the session to minimize the exposure window
• If you're not sure the viewer connected successfully, check Active Sessions on the Dashboard
