How do you know if you need a replacement? See the image above? If your Bluetooth Titan Security key has a “T1” or a “T2” on the bottom of it, you need a replacement. To get a replacement, you should head to Just make sure you are signed-in with the Google account used when you purchased the Titan Security Key and that link will recognize that you are eligible for a replacement.

What should you do if you have a bad key? Google recommends using your bad key to sign-in one last time from a secure space where no one is within 30 feet, and then immediately unpairing it.
