Backup and Restore FreeOTPhttps://github.com/freeotp/freeotp-android/issues/20#issuecomment-255749734
Connect your phone and run:
adb backup -f freeotp.bak org.fedorahosted.freeotp
That will store the FreeOTP data to the file freeotp.bak (on your computer).
To restore this data, just run (maybe you need to reinstall FreeOTP first) :
adb restore freeotp.bak
