Is Microsoft Edge supposed to work with U2F ?

Question

Is the Microsoft Edge browser supposed to work with the Nextcloud U2F ?

Summary

Since build 17723 - see https://www.yubico.com/2018/08/one-step-closer-to-passwordless-login-with-microsoft-edge-support-for-fido2-webauthn/ - Microsoft edge is supporting U2F, what works with i.e. an Yubico U2F key and i.e. a Microsoft Login.

Trying to access a Nextcloud instance with Microsoft Edge on a 1809 Version of Windows 10-64 (didn´t test other versions now) that is configured for U2F does not work "out of the box". The Nexcloud login page asks for a chrome-extension.

Regarding the documentation, Microsoft Edge of course is not listed. But documentation states about "a browser that supports the U2F standard", what Edge is doing in some way..

Maybe this issue is just relevant for Nextcloud Enterprise environment.

We use the u2f.isSupported() helper from https://github.com/grantila/u2f-api. If that returns false there is no support for the u2f standard, apparently. Is there a global u2f variable in the browser console?

You should probably use the WebAuthn APIs https://docs.microsoft.com/en-us/microsoft-edge/dev-guide/windows-integration/web-authentication
In Edge, this enables Windows Hello/FIDO2/U2F devices to work.
Generally, WebAuthn is the (backwards-compatible) successor to U2F and is supported by more browsers: https://developer.microsoft.com/en-us/microsoft-edge/platform/status/webauthenticationapi/?q=u2f

Awesome, @g6094199. Mind sending a PR to update https://github.com/nextcloud/twofactor_u2f#requirements? :)
