If you have already enabled two-step authentication via SMS or a mobile app, you have the additional option of adding one or more hardware security keys. Security keys are devices that connect to your computer via USB, Bluetooth, or NFC, and provide an additional form of two-step authentication.
If you have not yet done so, first set up two-step authentication by SMS or mobile app.
In your Profile settings under the Two-step Authentication section, click Add.
Select Add security key.
When prompted by the browser, plug in and tap your security key.
(The interface might look different depending on your browser.)
Next, enter a name for your security key. This will help you tell them apart if you add multiple security keys.
Next time you sign in, you can use this security key for two-step authentication instead of using receiving a verification code over SMS or through a phone app.
We support security keys through WebAuthn. This requires a modern browser.
