Personal media libraries frequently contain highly confidential snapshots—such as scans of passport documents, tax records, or private family moments—that should not appear while casually scrolling through the primary photo gallery. Google Photos provides a dedicated Locked Folder feature protected by device screen lock, fingerprint authentication, or face unlock. With modern cloud synchronisation, users can securely back up Locked Folder media across devices without exposing files to third-party photo pickers.
Architectural Overview of Locked Folder Isolation
Google Photos enforces strict local and cloud sandbox boundaries around Locked Folder assets:
- Gallery Omission: Items stored in Locked Folder are suppressed from the main photo grid, memory montages, shared albums, and search indexing.
- Application Sandbox Restrictions: Third-party apps possessing broad storage permissions cannot view, index, or access files residing within the encrypted Locked Folder directory.
- Encrypted Cloud Sync: Media backed up to Google Photos cloud is protected by industry-standard encryption protocols and tied strictly to your authenticated Google account credentials.
Setting Up Locked Folder on Android and iOS
To initialise and configure the Protected Locked Folder:
- Open the Google Photos application on your mobile device.
- Navigate to the Library tab (or Collections in updated UI layouts).
- Select Utilities and tap Locked Folder.
- Tap Set up Locked Folder.
- Authenticate using your biometric credentials (fingerprint, Face ID) or device screen PIN/pattern.
Enabling Encrypted Cloud Backup for Locked Folder
By default, Locked Folder contents remain strictly local to the originating device unless cloud backup is explicitly enabled:
- Open Locked Folder and authenticate.
- Tap the Cloud Settings icon in the upper-right corner.
- Toggle Locked Folder backup to the active position.
- Verify that your designated backup Google account has sufficient Google One storage quota available.
- Cloud synchronization immediately begins. You can now access your Locked Folder securely on photos.google.com and secondary linked devices.
Moving Photos and Videos into Locked Folder
Migrate sensitive media into isolated storage:
- Select the target images or video clips in your primary Google Photos timeline.
- Tap the More (three dots) menu in the upper toolbar or bottom action drawer.
- Select Move to Locked Folder.
- Review the prompt confirming that cloud copies in standard albums and shared albums will be deleted or transferred.
- Tap Move. The media disappears from your public gallery and resides exclusively inside Locked Folder.
