You have 2 ways to transfer app data to other devices:
Enable synchronization with Google Drive or DropBox, in this way the data transfer will be automatic on all your devices, including the desktop version.
Enable synchronization on the first phone (the one where you have the data in Password Cloud),
> Settings > Automatic synchronization > click on a Cloud icon and continue to Login
On the second phone, at the first installation, click Restoring data from the Cloud, now select the Cloud and log in with the same account ..
Now the device data will always be synchronized.
**Remember to always use the same Google account on all devices, otherwise data synchronization will not be possible.
