Platforms and Requirements
Yubico Authenticator is developed for both desktop and mobile platforms and is designed to work with USB, Lightning, and NFC-enabled YubiKeys.
YubiKey compatibility
Broadly speaking, YubiKeys from the following series are compatible with Yubico Authenticator:
- YubiKey Bio Series FIDO Edition
- YubiKey Bio Series Multi-protocol Edition
- YubiKey 5 Series
- YubiKey 5 FIPS Series
- YubiKey 5 CSPN Series
- Security Key Series
- YubiKey 4 Series
- YubiKey NEO
HOWEVER, not every Yubico Authenticator feature is supported on every platform, for every YubiKey model, or over every interface.
For example, Security Key Series keys only support FIDO2 and FIDO U2F. Therefore, none of the Yubico Authenticator features for PIV, OATH, and Yubico OTP are available for Security Key Series keys, regardless of platform and interface. Additionally, the iOS/iPadOS version of Yubico Authenticator does not support the full suite of FIDO2 features (compared to the desktop and Android versions of the app). The USB-C interface is also not supported for YubiKeys on iOS/iPadOS, and not all Android devices have a built-in NFC reader.
These are just a few examples — there are many other compatibility nuances.
To verify whether certain Yubico Authenticator features are available for your particular YubiKey and the device platform and interface you intend to use it with, refer to the Yubico Authenticator Functionality table, which contains full compatibility details and additional caveats.
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, x64 | Windows 10 or later, x64 |
| macOS | macOS 13 (Ventura) or later | macOS 10.15 (Catalina) or later |
| Linux | Ubuntu 22.04 or later | Ubuntu 20.04 or later (or equivalent) |
| Android | Android 13 (Tiramisu) or later | Android 5.0 (Lollipop) or later |
| iOS | iOS 15.0 or later | iOS 15.0 or later |
| iPadOS | iPadOS 15.0 or later | iPadOS 15.0 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 biometrics (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.
