Modern smartphone camera rolls accumulate a diverse mix of family memories, confidential document snapshots, financial receipts, and collaborative media. Managing this variety inside a single unsorted photostream presents privacy risks when passing a handset to a friend or when sharing family archives with a partner. Google Photos provides two dedicated privacy and automation architectures to address these requirements: Locked Folder and Partner Sharing.
Locked Folder isolates sensitive images behind on-device biometric security (fingerprint, Face Unlock, or PIN), removing them from search results, shared memories, third-party apps, and standard cloud backup streams. In contrast, Partner Sharing automates cloud-to-cloud library synchronisation, automatically sharing designated photos (such as images containing specific family members or captures starting from a chosen date) with a trusted contact without manual album sharing. This technical guide covers setup steps, cloud backup encryption toggles, and operational caveats across Android, iOS, and the web.
Feature Comparison: Locked Folder vs. Partner Sharing
The two features serve fundamentally opposing security models within Google Photos:
| Feature | Primary Privacy Goal | Backup & Sync Architecture |
|---|---|---|
| Locked Folder | Isolates confidential photos and videos behind biometric authentication. | Stored in a private, encrypted cloud container or kept exclusively on-device; hidden from third-party gallery apps. |
| Partner Sharing | Automates ongoing photo sharing with a single designated Google account. | Direct account-to-account library sharing with selective face detection filters and date filters. |
Step 1: Setting Up and Accessing the Locked Folder
Locked Folder is natively supported on Android (Android 6+), iOS (via the Google Photos app), and on the web at photos.google.com:
- Open the Google Photos app on your Android or iPhone device.
- Tap the Library tab (or Collections in updated app layouts).
- Scroll down to the Utility section and tap Locked Folder.
- Tap Set up Locked Folder.
- Authenticate using your device screen lock (fingerprint, Face ID, or PIN).
- Cloud Backup Toggle: Google Photos offers an option to Back up Locked Folder to your Google Account. If enabled, locked items are encrypted and synchronised across all your authenticated devices while remaining hidden from your main photo grid. If disabled, items remain strictly local to that single physical handset.
Step 2: Moving Sensitive Media into the Locked Folder
Once initialised, you can move existing photos or capture images directly into the encrypted container:
Moving Existing Photos
- In your main Photos tab, tap and hold to select the images and videos you wish to protect.
- Tap the More icon (three vertical dots) or the horizontal action pill and select Move to Locked Folder.
- Tap Move to confirm. Google Photos removes the files from your main feed, memories, albums, and on-device gallery caches.
Capturing Directly to Locked Folder on Pixel Devices
- Open the native Google Camera app on a Pixel device.
- In the upper-right corner beside the shutter button, tap the gallery thumbnail icon.
- Select Locked Folder. All photos captured during that session save directly to the secure vault without appearing in the temporary camera cache.
Step 3: Configuring Automated Partner Sharing
Partner Sharing eliminates the need to manually build shared albums for shared household memories:
- In Google Photos, tap your profile avatar in the upper-right corner and select Photos settings.
- Tap Sharing, then select Partner sharing.
- Tap Get started.
- Enter the email address of your partner (must be a valid Google account).
- Select what photos to share:
- All photos: Shares your entire current and future photo library (excluding Locked Folder items).
- Photos of specific people: Uses facial recognition clusters to share only images containing designated individuals (e.g., your children).
- Since this day: Sets a date boundary, preventing older historical archives from sharing.
- Tap Next followed by Send invitation. Your partner receives an in-app prompt to accept the connection.
Step 4: Auto-Saving Partner Photos to Your Personal Library
By default, viewing partner photos does not consume your personal Google storage quota. However, if your partner deletes an image, you lose access unless you save it:
- As the receiving partner, open Google Photos and tap Sharing > Partner sharing.
- Tap the More menu (three dots) in the partner sharing view and select Settings.
- Under Save to your account, choose All photos or Photos of specific people.
- When auto-save is enabled, photos shared by your partner are duplicated into your personal library. Crucially, as long as the original owner keeps their photo stored, the auto-saved copy does not count against your Google One storage quota.
Security and Operational Guidelines
- Factory Reset Warning for Local Locked Folders: If you keep Back up Locked Folder disabled, performing a factory reset, clearing app storage, or uninstalling Google Photos permanently deletes all media residing in the Locked Folder. Always back up or export locked media before device wipes.
- Exporting Media from Locked Folder: To restore an item to your normal gallery, authenticate into the Locked Folder, select the image, and tap Move. The image reappears in its chronological date position on the primary grid.
- Partner Revocation: You can disconnect Partner Sharing at any time from Photos settings > Partner sharing > Remove partner. Previously auto-saved photos remain safe in your partner’s library.
