# 2. Using "webauthn.io" to register a new Yubikey PIN.

<https://webauthn.io> is a site that allows you to test Passkeys (also known as "Webauthn") on your device.    If you have a new,  unprotected Yubikey,  we can use <https://webauthn.io> to force the initialization to assign a PIN.&#x20;

1. Plug in your unprotected Yubikey
2. Go to <https://webauthn.io>
3. Once at the site,  enter a bogus username (it doesn't matter what) and click on "register".

5. At this point,  you should be prompted to select a device you wish to store your new "Passkey".  Select the "User a different phone, table, or *security key*".&#x20;

7. At this point,  your browser should detect that your Yubikey is not protected.   You should be prompted to PIN protect your Yubikey.
