Support for many Services

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.

iCloud Synchronization

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 Mac. This feature is powered by Apples iCloud to make it as reliable as possible and can be turned on and off at any time.

Notification Center Widget

To make using OTP Auth as easy as possible, it includes a widget for the macOS Notification Center. Tap the notification center button in the top right, 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.

Safari Extension

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 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.
