Description of App
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) - Evernote (Two-step verification) - Facebook (Login Approvals) - GitHub (Two-factor Authentication) - Google Accounts (2-step verification) - Google Apps for Business (2-step verification) - HDE Mail Service (HDE Access Control OTP verification) - Yahoo! JAPAN (Yahoo! JAPAN one time password) 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.
