Yubico Authenticator 3.1

Yubico Authenticator is a companion application from Yubico AB that lets you generate one-time passcodes for two-factor authentication using a YubiKey. Instead of storing secrets on your phone or computer, it keeps them securely on the hardware key, helping protect your accounts if a device is lost, stolen, or compromised.

The app supports OATH TOTP and HOTP, works across platforms, and connects to your YubiKey over USB or NFC (on compatible devices). You can add accounts by scanning a QR code or entering details manually, then view time-based or counter-based codes whenever you need to sign in. It’s suitable for personal and enterprise use and works with most services that support standard authenticator apps.

Key benefits:

• Hardware-backed storage of OTP secrets on the YubiKey
• Cross-platform support with USB or NFC connectivity
• Easy enrollment via QR code scanning or manual entry
• Manage multiple accounts and multiple YubiKeys

Requirements: A compatible YubiKey with OATH functionality.
