How to Open a Locked Folder in Google Photos 2024 (Quick & Easy)
No, Google Photos does not offer a way to lock photo albums with a password. All photos added to your account, whether they are in an album or not, are accessible via search, appear when you choose an image from another app, and are otherwise freely available when browsing your Google Photos account.
The only exception is if you use the Locked Folder feature. It's a single folder stored on your device that hides any videos or photos you put in it. It's only available in the mobile app because it's a local feature: nothing you put in it is backed up online or stored anywhere else.
Importing albums is not allowed, but you can move as many photos and videos as you like to this password-protected folder, provided you have enough local storage space.
