Sharing photos between two accounts My wife and I use Google Photos to share pictures between our devices. We like it because it has Auto Backup and automatically syncs pictures between our two phones. 

To make this work, though, she has had to add my Google account to her phone, which comes with a host of annoyances. Even when we turn off sync for everything but Photos, many Google apps automatically switch her over to my account. The worst is Hangouts -- because I use Google Voice, she gets all of my text messages and voicemail, and I can't find a way to stop that.

Does anybody have some advice for either:


A way to sync photos using Google Photos, but without my wife getting all of my messages in Hangouts?
A non-Google app that will give us similar functionality for photos (automatic backup and syncing)?
Me and my wife use Picspro android app for Google photos.  It allows browser authentification to sign into any amount of Google Photo accounts without having to add the full Google account to the phone itself.  Personally,  We keep all our photos on her account,  using this app I can be logged in and view them and also upload to it so our photo collection is unified.  We also use this to upload to our Mum's accounts too and it works a treat. Settings>accounts>add account.  Untick the box next to "Use phones account" 

To fully back up all your Google photos to your PC, just go to Google Takeout and you can download any or all of your photos whenever you like. 

Hope this helps :)
