Platforms and Requirements 
==========================

Using the YubiKey Passkey Enabler requires a compatible Android device, security key, WebAuthn-enabled app, and WebAuthn-enabled website. Refer to the following sections for more information on these requirements.

.. _platforms-device-reqs:

Device requirements
===================

The YubiKey Passkey Enabler is supported for Android devices (mobile and tablet) running Android 14 and later.

To perform FIDO2 operations wirelessly over NFC, your Android device must have a built-in NFC reader. To verify device functionality, go to your device settings and search "NFC". If your search results return a mention of NFC connectivity settings, your device is NFC-capable.

.. note:: During device and app configuration, you will need to ensure that :ref:`NFC connectivity is toggled on <configuration-toggle-nfc>`.

Security key requirements 
=========================

Generally speaking, the app is compatible with FIDO2-capable security keys over USB and NFC connections. For Yubico products, this translates to the following YubiKey series:

- YubiKey 5 Series (standard, Enhanced PIN, FIPS, CCN, and CSPN)
- YubiKey Bio Series (FIDO Edition and Multi-protocol Edition)
- Security Key Series (standard and Enterprise Edition)

.. note:: To physically connect a USB-A YubiKey to an Android device with a USB-C or Micro-USB port, use a USB-A to USB-C adapter or a USB-A to Micro-USB adapter, respectively.

Some YubiKey Passkey Enabler features are dependent on security key capabilities. For example, the app will only prompt for a fingerprint if you have a security key that supports fingerprint biometrics, such as the YubiKey Bio Series.

Security keys from other vendors may work with the YubiKey Passkey Enabler, but complete compatibility is not guaranteed by Yubico.

.. tip:: To confirm if your security key supports NFC, connect your key to your Android device via USB and open the YubiKey Passkey Enabler app. Look for **Supported interfaces** on the home screen; if your security key supports NFC, you will see **NFC** listed here.

.. _platforms-browsers:

Compatible WebAuthn-enabled apps
================================

Performing FIDO2 operations with the YubiKey Passkey Enabler requires a compatible WebAuthn-enabled app, such as a browser. The following apps have been tested and confirmed to be compatible by Yubico:

- Google Chrome
- Mozilla Firefox
- Microsoft Edge
- Samsung Internet
- Microsoft Teams
- Booking.com
- Roblox
- Uber
- Amazon Shopping

If you run into issues using the YubiKey Passkey Enabler with any of the compatible apps listed here, please report the issue by `submitting a request <https://support.yubico.com/s/requests>`_ with our customer support team.

Other apps may be compatible but have not been thoroughly tested by Yubico. WebAuthn implementation differs across apps, and nonstandard WebAuthn operations may affect compatibility with the YubiKey Passkey Enabler. 

WebAuthn/FIDO2 website support
==============================

Once you have a compatible Android device, security key, and WebAuthn-enabled browser, using the YubiKey Passkey Enabler to perform FIDO2 operations (such as registering or authenticating with a passkey) requires a WebAuthn-enabled website. 

To verify whether a site supports WebAuthn, look for terms like "passkey", "security key", and "FIDO2". For an example of a WebAuthn-enabled site, see `passkey.org <https://passkey.org/>`_.
