Backround: FreeOTP is a Google Authenticator compatible open source Android app, made by Red Hat. Available at https://play.google.com/store/apps/details?id=org.fedorahosted.freeotp .
Google authenticator does not allow backuping the secrets with adb, to backup one needs a rooted phone. FreeOTP however allows adb backup. The backup file obviously can be restored to any android phone, but for easy transfer to other phones, you can create qr codes with this app. The app does all processing locally, no data is sent anywhere.

Make an adb backup of FreeOTP, (details on how to do this are currenly left as an excercise for the reader. While you are doing the backup, consider the above warning!). Open the adb backup file (.ab) with this app. Read the displayed qrcodes with the authenticator app on your other phone.
The author has tested the app with current Google Chrome and Mozilla Firefox on Ubuntu 14.04 in September 2015, generated qrcodes have been succesfully imported in FreeOTP and Google Authenticator on Android and Microsoft Authenticator on Windows Phone 8. Other browsers probably do not work.
