Perfect way to secure your online logins


After having tried about a half-dozen similar apps, stumbled upon this simple authenticator that works great. I like the ability of adding an entry one one of my iOS devices, and have it sync to all my other iOS devices. Another nice feature is that I can sort my entries, and add categories (folders) to put them in, so I can have a folder for home (personal) sites, another for work ones, and yet another one for rarely-used sites, etc. It is capable also of allowing me to change the icon of each entry with an icon of my choosing, and I can rename the name of each entry, as well as the email address associated with each entry. As for support, the author was quick to reply to my requests for help on a couple of occasions (when I had issues due to my own stupidity, I might add). The icing-on-the-cake of this app, is that I can also see all of my entries on my Apple Watch, with the press of an icon on my watch face. Well-worth the cost of the Pro version of this app!

Great 2-Factor App!


I’ve been combing through two factor apps to find one that is responsive and well designed. I’ve found it!

Apps like Google, Microsoft and Lastpass Authenticator are all responsive but fairly simple in their functionality (only an app view). And the other highly recommended app out there, Authy falls short in its responsiveness and it’s poor design and formatting of both the app and widget leave a lot to be desired.

This app hits it all out of the park. It’s fast to load, full of features including iCloud syncing, a very responsive Watch app (on a 1st gen watch) simple widget and is all formatted and designed very cleanly. I wish this app got as much press as the major names. It blows away the competition.

One big drawback


I like the app, it is simple, user friendly and polished. I’m not a fan of syncing second factor codes to the cloud, but this feature can be turned off. TouchID support is great and adds an additional layer of security. Touch ID can also be turned off in favor of password auth. However the one big drawback in my opinion is that the app can reveal the secrets. If anyone ever gets access to the phone it might be possible to not only get single codes but the secrets from which the codes are generated. That’s not good. Nowadays certain third parties might force a finger on Touch ID to access secrets. It would be better if app just could not reveal them. But of course this puts the responsibility on the user to backup their QR codes offline.

Developer Response

Hi there!

First, let me thank you for your positive feedback :).

About being able to show the secrets of an account: I did this so that a user is never locked to OTP Auth and can always switch to another app. To make sure of this, you have to implement a common account format that every app understands. In case of OTP Auth, this is the QR code we always scan to configure new accounts. However, the QR code contains the secret in plaintext as well. Thus, if OTP Auth can generate and show those QR codes it might as well show the secret.

I do not like how every app tries to force and keep you in his environment nowadays. Thus, I wanted to be a good example :).
