Yubico Authenticator is a desktop and Android companion app for managing YubiKeys and accessing one-time passwords.
About Yubioath
Yubico Authenticator (yubioath-flutter) is a companion application for YubiKey hardware security keys, available for Windows, macOS, Linux, and Android. It lets users manage their YubiKey and access OATH one-time passwords stored directly on the device, with no internet connection required for OTP functionality. The app supports configuring YubiKey PINs, fingerprints, WebAuthn/FIDO passkeys, PIV private keys and certificates, slot-based credentials like Yubico OTP and static passwords, and factory resetting YubiKey data. It is compatible with any USB or NFC-enabled YubiKey, and stores credentials on the hardware key rather than the host device to reduce account takeover risk.
