About HENNGE OTP Generator
HENNGE OTP Generator is a virtual device application for multi-factor authentication (MFA), so-called two-step verification, which generates time-based one-time passwords (OTP) complying with RFC 6238 (TOTP: Time-Based One-Time Password Algorithm).
HENNGE OTP Generator supports multiple authentication source. You may use QR codes, or URLs copied onto the clipboard to add authentication config.
Tested for various platforms

We tested TOTP QR codes from, and believe it works with:

- Dropbox (Two-step verification)
- Evernote (Two-step verification)
- Facebook (Login Approvals)
- Gandi (Two-factor Authentication)

- HENNGE One (HENNGE Access Control OTP verification)

Additional security
==============================

Limitations
==============================
- To make OTP work, make sure your clock is in sync
- Only supports 6-digits
