Re: [FIDO-DEV] Chrome on Android support of security keys

[John Bradley]

CTAP 2 works on android over USB.  I have it on good authority that work has recently started on NFC in play services.  

I have been waiting years for this,  I expect positive news in months not years.

Hello all,

According to the release notes at this page https://support.google.com/product-documentation/answer/14343500#zippy=%2Cearlier-version-release-notes%2Cjanuary , NFC Authentication is meant to work natively for CTAP2. Do a search for "nfc" or look at Security & Privacy under January 2026. It states authentication via NFC should work for CTAP2 now.

Of course, it still doesn't show an NFC option. And no response from Google either about this.

Hello everyone,

just went through an update of our old U2F+CTAP2.1_PRE authenticator code and some platform

interoperability tests:

As a result (on Android 16, PlayServices 25.44.35) I can tell Android still does not support UV and

discoverable credentials via NFC. If selected you can't use NFC, if not selected Android falls back

to U2F. 

It's a real shame not supporting UV in 2025 on Android. iOS/macOS/Windows works.

I'm now going to tell users to move away from Android, if they want authenticated credentials.

Best,

Christian

Hello,

That are great news, thanks!

I take the opportunity to also ask if there is somewhere good material for implementing NFC support on an authenticator.

As of now I know there are:

- a dedicated part in the FIDO2 spec (https://fidoalliance.org/specs/fido-v2.1-ps-20210615/fido-client-to-authenticator-protocol-v2.1-ps-errata-20220621.html#nfc)

- a dedicated spec for U2F https://fidoalliance.org/specs/fido-u2f-v1.2-ps-20170411/fido-u2f-nfc-protocol-v1.2-ps-20170411.html

But I'm looking for a more extensive specification, and maybe some tooling, like a debug application or something?

Thanks again,

Xavier
