This app is used to calculate one-time passwords required to log into your accounts after you enabled two factor authentication. It works with many popular services like Google Mail, Amazon, GitHub, Dropbox and many more.
OTP Auth can be used with any service that uses one time passwords. This includes popular services like Google Mail, Dropbox, Evernote and many more. You only have to enable two factor authentication. For a list of services that support two factor authentication you may want to take a look at twofactorauth.org.
OTP Auth supports synchronize all your accounts between your devices. This allows you to add a new account on your iPhone and later request a code on your iPad. This feature is powered by Apples iCloud to make it as reliable as possible and can be turned on and off at any time.
To make using OTP Auth as easy as possible, it includes a widget for the Notification Center. Swipe down, tap an account in the widget and your code is copied into the pasteboard. From there you can paste it where ever you need it.
If you are browsing the web using Safari, OTP Auth has something special for you: A Safari extension. Just launch this extension, choose an account and the code of the chosen account will be inserted into the website right where you need it.
OTP Auth is the only app out there that allows you to export accounts. They are saved in an encrypted file using AES-128, one of the strongest encryption algorithms out there. If you have apps like Dropbox, Google Drive or Microsoft OneDrive installed you can even export the files to these third party storage services.
Instead of exporting just one account, OTP Auth also supports exporting all accounts at once. This allows you to easily create backups of all your accounts. Backups are encrypted with the same AES-128 encryption algorithm used for exporting one account and can be saved to third party storage services, too.
To secure your accounts from unauthorized access, OTP Auth can be secured using Touch ID or a password if your device does not support Touch ID.
OTP Auth fully respects your privacy. Unlike other apps, your accounts are not sent to any server (except you enable iCloud Sync). Also OTP Auth does not show any ads and does not collect any usage data. The app works offline without any restrictions.
The issuer icons are maintained by myself and new icons require an app update. Drop me a mail with some suggestions and I will add your issuer icon to the next version of OTP Auth.
Attention: If your issuer icon is rather dark, I will also need a light version. This is due to the dark icon not looking very well in the notification center (where the background is dark as well). Of course, if your icon is rather light, I will also need a darker version which looks good in the app.
Unfortunately, there is not much that can be done about it besides remembering the password. The password is used to encrypt your accounts when saving them on disk. Thus, they cannot be restored without the password. Your only option is to restore the accounts using account backups (*.otpauth and *.otpauthdb files) whose password you know. In this case proceed as follows:
The support for app extensions in iOS 8 is known to be kind of buggy. There are some general problems with access to shared containers and such. There are some things you can try to solve the problem though:
It’s a little bit tricky. You need to hold the iPhone in a way such that the QR code is bigger than the marked area on the iPhone. The reason for this is, that Dropbox uses veeeery big QR codes. When holding the iPhone in a way such that the QR code is exactly in the marked area, the QR code is too small for the iPhone to be recognized.
