HDE 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).

HDE 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:
- Amazon Web Services (AWS Multi-Factor Authentication)
- App.net (Two-Factor Authentication)
- Dropbox (Two-step verification)
- Facebook (Login Approvals)
- Google Accounts (2-step verification)
- Google Apps for Business (2-step verification)
- HDE Mail Service (HDE Access Control OTP verification)

Additional instant security with PIN
==============================
HDE OTP Generator is equiped with it's own PIN screen which prevents strangers or children from casually accessing your OTPs, even when you are physically away from your phone.

Limitations
==============================
- To make OTP work, make sure your clock is in sync.
- Only supports 6-digits/30 seconds OTPs.
- Does not support pure HOTP codes.
