Yubico Authenticator is an open-source companion app for YubiKey hardware keys, published by Yubico. It runs on Windows, macOS, Linux, Android and iOS and manages the one-time password accounts stored on a YubiKey.

Yubico Authenticator is the companion app for YubiKey hardware keys, published by Yubico under the Apache 2.0 license. Its README describes it as a way to manage the YubiKey and access one-time passwords, with a desktop app for Windows, macOS and Linux and an Android app.

The supported systems listed in the project are Windows 10 and later, macOS 13 and later, Ubuntu 22.04 and later, and Android 13 and later. The iOS version is a separate app that the project links from its README. Because the app is built around a YubiKey, it is useful only if you own a compatible key.
