Second Factor - Hardware OTP

Designed with security in mind this 100% native application lets you generate OTP codes for all services with TOTP second factor. This application uses Sandboxing feature, and not requires network access - so it is guaranteed by operating system that your keys or authentication codes will not leak anywhere via network. * NOTE: You need to have Yubikey device to generate codes. This app does not provide storage for your OTP keys! * NOTE: Application supports only modern yubikeys with TOTP CCID support (for example Yubikey 4, refer to manufacturer documentation). Main features of application: * Fast and stable 100% native application * TOTP with SHA1, SHA256, SHA 512 (if supported by you hardware) * Both 6 and 8 digits codes * PIN * Sandboxed app - you dont have to trust me. Your keys and codes are protected from leakage by OS * Adding OTPs from QA codes by drag-drop image files or by scanning screen (although app is able to capture image from screen, it is processed locally and not sent anywhere - it is guaranteed by Sandox function of macOS) Features not yet supported (planned for future releases): * Codes protected with hardware button touch * HOTP codes * Codes with non-standard period. At this time only codes with 30 seconds period (used by almost all popular services) are supported Please note: if yours hardware key contains any of not-yet-supported OTPs - they will not be shown in this application. --- Yubico and YubiKey are registered trademarks of Yubico Inc.
