FIDO not working with Yubikey 5

[CubicrootXYZ]

Hey,

I am using the PlugIn now for a few years with the TOTP-Option. Now I got a Yubikey 5, registering it worked (console error: setting getter-only property "u2f"), but if I want to login it shows the page but my Key doesn't light up, pressing the key doesn't do anything.

I am Using WordPress 5.1.1 and https, also tried to delete the key and set it up a few times. Tried Chrome, Edge and Firefox.

Thanks for reporting the issue!

Which browser did you use for registering the device? Could you please paste the full error message you got when registering the device?

I suspect it didn't actually register the device due to that error.

Registered it with Firefox 66.0.2 and got this error:

TypeError: setting getter-only property "u2f"[Weitere Informationen] u2f-api.js:17:5
    <anonym> https://[mydomain]/wp-content/plugins/two-factor/includes/Google/u2f-api.js?ver=0.1.0-dev.2:17

Registered it with Chrome 73.0.3683.103 => no error => also not working

Sounds really similar to #211.

Did you enable the U2F feature flag?

Yeah I enabled it

Here is a video showing key registration on Firefox 67 with the U2F feature flag enabled:

I've opened #283 to address the JS warning in the browser console but that isn't impacting the registration and sign processes.
