Platforms and Requirements
Yubico Authenticator is developed for both desktop and mobile platforms and designed to work with USB, Lightning, and NFC-enabled YubiKeys.
However, not every Authenticator feature is supported on every platform. Similarly, not every Authenticator feature is supported for every YubiKey model. For example, the iOS/iPadOS versions of the app do not currently support any FIDO2 features (regardless of YubiKey used), and Bio Series YubiKeys do not support any OATH features (regardless of app platform).
Compatibility between YubiKey interface (USB, NFC, Lightning) and platform is also device-dependent. For example, USB-C is currently not supported on iOS/iPadOS, and not all Android devices have a built-in NFC reader.
For a complete breakdown of Yubico Authenticator functionality by platform and connection type for each YubiKey model, see the Yubico Authenticator Functionality table.

Supported platforms
Fully Supported - the platform versions that Yubico builds and tests on and commits to supporting.
Best Effort - the app is expected to work, but development is supported through community testing and full functionality cannot be guaranteed.

| Windows | Windows 10 or later | Windows 10 or later |
| macOS | macOS 11 or later | macOS 10.15 or later |

WebAuthn browser support
The Web Authentication API (also known as WebAuthn) is a specification that enables FIDO-based authentication to websites.
WebAuthn support is not uniform across browsers. This does NOT affect your ability to manage FIDO credentials (passkeys and fingerprints) within the Yubico Authenticator app, but your ability to use your YubiKey’s FIDO credentials for authentication will be dependent on your specific browser and device.
For a complete list of browser support for various authentication features across desktop and mobile platforms, please see the WebAuthn Compatibility page.
