# What is the Tunnel Code in Bridge?

The Tunnel Code is a six-digit number that appears on both your Mac and the other device after you pair. If the two numbers match, you know you're linked to the right device and nobody is sitting in the middle of the connection.

Check it every time you pair. On the Bridge app, choose **Codes match — Confirm** when they agree. You can also see a paired device's Tunnel Code later on its row in the Devices tab and on the Devices card on Home.

If the numbers differ, don't confirm.
