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).

- Yahoo! JAPAN (Yahoo! JAPAN one time password)

Additional security

Slick design, Solid App

Does just what it needs to, and has a Watch extension to boot! Thanks! My only request would be that the Watch component include a Complication for quick from-the-watch-face access.

Works ok, but I got it for the watch integration which kinda sorta almost works if you hold it right.

If you change the configuration, you have to reinstall the watch app to see the updates. Sometimes it works and it's magical when it does... but I wish it was less magical and more consistent.

Nice Google Authenticator replacement

I was looking for a Google Authenticator replacement, and this app was recommended on the Security Now podcast. It's straightforward and non-gimmicky, nicely laid out and easy to use.

My only minor complaint is that I find the faux LCD calculator numbers a little hard to read. I'd prefer just a plain, unadorned font.
