What is HENNGE OTP Generator?

HENNGE OTP Generator is a free and open-source software application for generating one-time passwords (OTPs) for two-factor authentication security. It allows users to easily generate TOTP (time-based) and HOTP (counter-based) codes that are compatible with Google Authenticator, Authy, and other OTP authenticator apps.

As an open-source OTP generator, HENNGE offers full transparency into its code and cryptography. It uses industry standard algorithms like HMAC-SHA1 and SHA256 to securely generate unpredictable 6-digit and 8-digit OTP codes based on the current time or an event counter. Users can customize the OTP code length and hashing algorithm to meet the requirements of the service they are authenticating to.

HENNGE has a simple and intuitive graphical interface for quickly generating OTP codes even when offline. It can export the OTP secret in a QR code to easily set up OTP integration with a mobile authenticator app by scanning the code. The software also includes advanced options like manually specifying the OTP counter value.

By providing an easy way to enable two-factor authentication, HENNGE OTP Generator improves account security and prevents unauthorized access. It is available free of cost for Windows, Linux, and macOS platforms.
