Hi Mozilla 😄
I was testing the WebAuthn functionality in Firefox via https://webauthn.io/. When I filled my user name and click "Register", Firefox popped an message saying: webauthn.io wants to register an account with one of your security keys. You can connect and authorize one now, or cancel.
If you are an repeated user, this message may come obvious to you, but as a first timer, it's quite confusing.
If possible, I would like to suggest at least a change of wording, so it says something like: Please plugin a security key to continue, or click Cancel to cancel the process.
Or even better, show a list of all connected security key and let the user select which one they want to use, and also show a message somewhere near the list explaining how to connect a new security key.
That's all, thanks!
