WebAuthn Provider for Two Factor

Thank you so much for this plugin!!  

In February 2022 Chrome changed things so hardware security keys would no longer work with the "Two Factor" plugin. Installing this add-on gets it working again. 

I had to change the "User Verification Requirement" to "Discouraged" in order to use my existing Yubikey (without re-adding it). Otherwise, it asked for a PIN but then wouldn't recognize my key.

Hopefully it can get merged directly into the Two Factor plugin soon? 😁🙏

Two Factor works with hardware keys again!

Thank you for bridging the gap while we wait for the PR. 
This is what Open Source is all about. 

FIDO U2F WebAuthn for Two Factor


This is helpful for evaluating purposes of the code. As this plugin is part of a security level all the code should be readable easily for auditors.



Besides that, well done.Thank you.


Works well for my use case but please provide unminified JS files.


This is great. You can literally log into WordPress with 2FA using one touch (password manager with auto-login combined with this for 2FA). Beats using an authenticator app any day.


One touch 2FA is a dream
