Adding a passkey makes it mandatory as MFA on other devices

I will add a toggle to make you opt-in to using it as two-factor authentication. I've tried to make it clear in the UI that it's a two-factor authentication method, but I haven't made it clear enough. I can also see why people would like to use it not as two-factor authentication, it's just a bit of work to ensure this change is rolled out safely. This fix will be available within the next few hours. For anyone currently having issues accessing their account, feel free to email support@fluxer.com and we'll get it sorted.
