Google today announced that its Titan Security Key kits are now available in Canada, France, Japan and the UK. Until now, these keys, which come in a kit with a Bluetooth key and a standard USB-A dongle, were only available in the U.S.

The keys provide an extra layer of security on top of your regular login credentials. They provide a second authentication factor to keep your account safe and replace more low-tech two-factor authentication systems like authentication apps or SMS messages. When you use those methods, you still have to type the code into a form, after all. That’s all good and well until you end up on a well-designed phishing page. Then, somebody could easily intercept your code and quickly reuse it to breach your account — and getting a second factor over SMS isn’t exactly a great idea to begin with, but that’s a different story.
