Yubico Authenticator

Yubico Authenticator generates two-step verification codes for online accounts on mobile and desktop. It supports TOTP and HOTP, and you can add credentials by scanning QR codes from services you want to protect. Credentials are kept in a YubiKey secure element; Yubico says they cannot be extracted. Since the portable YubiKey holds the credentials, the same codes are available through the desktop and mobile apps. The mobile app supports tap-and-go on NFC-enabled devices, and credentials can be added to a YubiKey with a touch or NFC tap. Yubico says users can unlock a YubiKey with Face ID or Touch ID. The app can display OATH codes, manage a YubiKey’s FIDO PIN, or perform a factory reset. It is free and open-source software, listed at 0.00 USD per free, and supports Windows, macOS, Linux, iOS/iPadOS, and Android. The desktop app requires a YubiKey to generate and display OATH credentials. Yubico provides a user guide in its product documentation.
