How to log in to your CommBox OS Account

Applies To

There are three ways you can log into your CommBox OS Account:

3. Tap on the NFC card reader with your enrolled NFC device

Step-by-Step Instructions

Log in with QR Code

Step 1

On your CommBox screen, tap the Login button from the sidemenu.

Step 2

This will pop the Account pop-up. Scan the QR code using your mobile device.

Step 3

Choose a login method:

💡 Tip: The login process uses a secure device code flow—ideal for shared classroom or staffroom devices.

Step 4

Set your session time. You can choose from:

• 10 minutes

• 15 minutes

• 30 minutes

• 1 hour

• Custom duration

This gives you control over how long your login stays active.

3. Enter the on-screen code into the browser at CommBox Exp and then follow the prompts.

Log into via NFC card

1. Tap your enrolled NFC device on the NRC reader in the bezel of the CommBox Classic S5 or on the sensor box of the Classic S4 or S4+. The senor box is purchased separately. 
2. Enter the PIN you set when you enrolled your NFC device

Troubleshooting / What to Do If It Doesn’t Work

  Try adjusting the angle or lighting

• Can’t see the Login button?
  Make sure your CommBox OS Accounts are enabled on your screen. On a Classic S5, they can be disabled by your IT Manager. 

• Session expired quickly?
  Choose a longer session time during login or log in again using the same method.
